Abstract

This research work aimed at isolation and characterisation of essential oils of Mangifera. indica (M. indica) leaves. Phytochemical screening was carried out to determine the bioactive components present in the leaf sample as well as the antimicrobial activity of the crude ethanolic extract. The percentage yield of essential oils (colourless) of the leaf was 0.19%. The phytochemical screening revealed the presence of alkaloid, glycoside, flavonoid, saponin and tannin.  Steroids was absent in the extract. The antimicrobial evaluation of the essential oil of M. indica leaf revealed a significant activity (zone of inhibition). The percentage (%) of Diphenyl picryl hydrazine (DPPH) scavenged of antioxidant activities for the essential oils of M. indica at different concentration of 5µl, 10µl, 25µl and 100 µl showed a significant antioxidant activity. In concluded results, it’s clearly observed that, when the concentration of both ethanolic extract and essential oils leaf sample increases, the antimicrobial and antioxidant properties increases when compared to the standard (Amoxicillin) and that of essential oils has a significant property than other extracts. Considering the results of phytochemical screening, it’s also a potential source of cost-effective food supplements, nutritive ingredients and antibacterial agent for improving human health and curing acute and chronic diseases. The GC-MS analysis of the essential oils for the leaf sample revealed fifty two (52) different chemical compounds which include Alloaromadendrene, Humulene, Bicyclo[4,4,0]dec-1-ene, 2-isopropyl-5-methyl-9-methylene, Bicyclo[7.2.0]undec-4-ene,4,11,11,-trimethyl 8-methylene-,[1R-(1R*,4Z,9S*)].

Abstract

Many medicinal plants and their essential oils are used to treat or prevent diseases without the risk of mutagenicity, carcinogenicity, or teratogenicity. Eucalyptus essential oils are commonly used as preservatives, flavoring agents, and various consumer goods. Eucalyptus leaves are being widely studied due to their volatile essential oils, including 1,8-cineole, p-cymene, α- and β-pinene, limonene, citronellal, citral, eudesmol, terpinen-4-ol, terpineol, α–phellanderene, and 9β-sitosterol. Among these compounds, 1,8-cineole is the most abundant. Eucalyptus leaves are rich in flavonoids and phenolic compounds and are thus a great source of antioxidants. 2,2-Diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays were used to measure antioxidant capacity. The antioxidant activity of Eucalyptus essential oil is stronger than that of standard antibiotics such as erythromycin, cefixime, and gentamicin due to the presence of significant terpenoids in addition to phenolic chemicals and flavonoids. A lower IC50 indicates greater antioxidant potential. Phenolic compounds and flavonoids are often associated with beneficial health outcomes, including anti-inflammatory and antioxidant effects, anticancer properties, reduced risk of cardiovascular diseases, prevention of age-related neurodegenerative diseases, and prevention of Alzheimer’s disease. Flavonoids also play essential roles in plants, including protecting against reduction, fertility, reproduction, and infection. Due to their anti-inflammatory, antioxidative, and immunomodulatory properties, flavonoids are crucial for pharmacological, medical, and nutraceutical applications.

Abstract

Epilepsy is a prevalent neurological condition characterized by repetitive seizures, necessitating the exploration of efficacious treatments. Justicia insularis, a plant with a historical use in treating convulsions and epilepsy, has garnered attention as a potential antiepileptic agent. This study aimed to investigate the antiepileptic properties of Justicia insularis leaf extract, focusing on generated seizure models in mice. The analysis of variance (ANOVA), specifically one-way ANOVA, was utilized to assess the statistical significance of the data. Seizure models were employed to evaluate the antiepileptic effects of Justicia insularis leaf extract. The p-values obtained from the one-way ANOVA were significant, with values of ap<0.005, bp<0.01, and cp<0.001. These results suggest the statistical significance of the observed effects in the seizure models. This study provides valuable insights into the therapeutic potential of Justicia insularis leaf extract as a treatment for epilepsy. The significant findings underscore the importance of further research into the use of natural medicines for managing epilepsy, potentially offering new avenues for treatment.

Abstract

The leukocyte count examination in tuberculosis infection serves to monitor the inflammation caused by Mycobacterium tuberculosis. An increasing leukocyte count can lead to complications such as pleuritis. The purpose of this study was to determine the total leukocyte count of pulmonary tuberculosis patients at RSUD Gambiran, Kediri City, based on gender and age. This research was a descriptive retrospective study. Data analysis was conducted using Microsoft Excel and presented in the form of tables and diagrams. The results of this study showed that pulmonary tuberculosis infection was more prevalent in males, with 26 individuals (62%) affected. In terms of age groups, the highest infection rate was in the 21-60 years age range, with 30 individuals (71%) affected. As for leukocyte count elevation (leukocytosis), it was more commonly observed in males with a count of 14.57 µL. In terms of age groups, leukocytosis was frequently observed in the 21-60 years age range, with a count of 48.66 µL. Out of the 42 samples, 19 individuals had a normal leukocyte count, while the remaining 23 individuals experienced leukocytosis. From the results of the study, it can be concluded that not all pulmonary tuberculosis patients experience leukocytosis; some patients maintain a normal leukocyte count.

Abstract

To ascertain the comparative effects of ripe and unripe Lime (Citrus aurantifolia) on spermatozoa and gonadosomatic index evaluation in matured male Wistar rats; exploring the idea that both ripe and unripe Lime (Citrus aurantifolia) might or might not positively affect semen quality, crucial for male fertility. Twenty-eight (28) sexually mature male Wister rats, aged 9–10 weeks and weighing between 211.50g and 217.00g, were divided equally into seven groups (1 to 7); with Group 1 serving as the control and Groups 2 to 7 receiving 25%, 50%, and 75% concentrations of ripe lime juice (RLJ) and unripe lime juice (ULJ) respectively. The findings indicated that ULJ had a higher concentration (0.1mg/ml) compared to ripe lime RLJ at 0.08mg/ml, although both had approximately the same LD50 value of 1581.138mg/kg. RLJ, at different concentrations, adversely impacted the reproductive performance of rats, leading to decreased progressive motility, livability, sperm count, testicular size, and sexual drive. However, ULJ did not exhibit these effects. A 75% concentration of RLJ showed anti-prostatic activity, causing a reduction in prostate size, which was more pronounced than that of the same ULJ concentration. Importantly, both RLJ and ULJ did not have a significant impact on the sizes of the liver, spleen, heart, kidneys, and lungs, with these visceral organs maintaining normal sizes comparable to the control group (statistically, p>0.05).The findings suggest that RLJ or ULJ consumption, particularly at the highest concentration, may lead to alterations in reproductive performance, hence such consumption should be discouraged.

Abstract

Lipase is one of hydrolase enzyme that catalyzed hydrolysis reaction of triacylglycerols into free fatty acids and monoglycerides or glycerol. These biocatalysts are widely used in several industries, namely food and pharmaceutical industry. The activity of lipase can increase significantly if the substrate forms an emulsion. Since biosurfactant has been known to have emulsification characteristic, the effect of biosurfactant addition into lipase is necessary to be investigated. It is the first report that evaluate the effect of microbial surfactant on lipase activity. The purpose of this research is to analyze the stability of biosurfactant emulsion under various conditions, such as salinity and pH as well as their potential to enhance lipase activity. Biosurfactant used was Halomonas elongata BK-AG18 from the collection of Biochemistry Research Group ITB, Bandung, Indonesia. It was found that after the addition of NaCl, there was no significant decrease in the emulsification activity of the biosurfactant. The emulsification index (IE24) of biosurfactant with several NaCl concentrations (2, 5, 10, 15, 20, and 25%) was obtained around 50%. Stability test of biosurfactant at pH range 4-10 showed the highest IE24 of biosurfactant was obtained at pH 6. The effect of biosurfactants on lipase hydrolysis activity is also discussed in this article. Lipase hydrolysis activity was tested using p-nitrophenyl palmitate substrate. The highest lipase activity was obtained after the addition of 70% biosurfactant (v/v) at 0.026 units. This study shows that biosurfactant from H. elongata BK-AG18 has the potential to increase lipase activity.

Abstract

Justicia insularis (Family-Acanthaceae) is used in Ibibio ethnomedicine to treat malaria. The leaf extract and fractions of J. insularis were investigated for antioxidative stress and hepatoprotective activities in Plasmodium berghei-infected mice. The leaf extract (100-300 mg/kg, p.o.) exerted significant (p<0.05) antimalarial activity against P. berghei infection in curative test with ethyl acetate fraction demonstrating the highest activity.  The extract/fractions treatment caused significant (p<0.05) reductions in liver enzymes (ALT, AST and ALP), total and conjugated bilirubin of the treated infected mice and also decreased significantly (p<0.05) total protein and albumin levels of the treated mice relative to control. The leaf extract and fractions further improved significantly (p<0.05) the levels of oxidative stress markers enzymes and molecules (CAT, GPx, GST, SOD) of the treated infected mice with no significant (p>0.05) effect on GSH. The MDA levels in the livers of the treated infected mice were significantly (p<0.05) reduced relative to control. Histology of liver sections revealed absence or significant reductions in pathological features in infected mice treated with leaf extract (100 mg/kg), DCM and ethyl acetate fractions compared to untreated infected mice. These results suggest that the leaf extract/fractions of Justicia insularis possess antioxidative stress and hepatoprotective potentials, which is an added advantage to its antimalarial property.

Abstract

Mangrove plants have been widely used by people in various regions of Indonesia as traditional medicine for the treatment of wounds, fever, diarrhea, and others. Extreme habitat in coastal areas with high salinity and low oxygen level makes mangrove plants produce a variety of unique secondary metabolites and are rich in antioxidants. Although there have been studies on phytochemicals and antioxidant activity conducted, the study of mangroves in Bali, Indonesia, has not been widely explored. This study aims to determine the compounds contained in mangrove leaf extract and their antioxidant activity. The species to be studied is Sonneratia alba, which is commonly found in the Ngurah Rai Mangrove Forest, Bali, Indonesia. In this experimental study, compound extraction was carried out by maceration method using n-hexane solvent. Phytochemical screening using qualitative methods and GC-MS was carried out to determine the phytochemical compounds in the extract, while 1,1-diphenyl-2-picrylhydrazyl (DPPH) method was used to determine antioxidant activity. The result showed that the n-hexane S. alba mangrove leaves extract display strong antioxidant activity with IC50 value of 64.432 ± 7.675 ppm. The qualitative phytochemical tests showed that the extract contained phenol and steroid, which are known to have antioxidant properties. Moreover, GC-MS analysis showed that there are two compounds with the largest %area namely gamma-sitosterol and dl-alpha-tocopherol (52.88% and 7.77%, respectively), which have been reported to have antioxidant activities. To conclude, these findings demonstrate that n-hexane extract of S. alba mangrove leaves from Ngurah Rai Mangrove Forest, Bali, to have potential antioxidant activity.

Abstract

Effect of processing on the nutritional composition of groundnut seeds were carried out using standard analytical methods. Raw, boiled and fried groundnut seeds were analyzed for proximate composition, mineral contents, and phytochemical screening. The result reported that the raw, boiled, and fried contains (5.357±0.190%, 4.545±0.050% and 3.896±0.015%, moisture contents), (2.401±0.011%, 3.225±0.004% and 2.816±0.001%, ash contents), (46.591±0.001%, 25.333±0.003% and 48.012±0.953%, crude fat), (4.126±0.887%, 15.001±0.030% and 7.692±0.002%, crude fibre), (19.520±0.040%, 21.580±0.040% and 23.540±0.000%, crude protein), (22.005±0.587%, 30.316±0.056% and 14.044±0.939%, carbohydrate) respectively. A significant difference was observed. Processing has significant effects on the mineral components of the seeds. The results revealed that raw, boiled and fried contains (56.900mg/100g, 48.400mg/100g and 35.00mg/100g Sodium), (0.215mg/100g, 0.185mg/100g and 0.540mg/100g Zinc), (65.500mg/100g, 42.700mg/100g and 25.500mg/100g Magnesium), (0.218mg/100g, 0.230mg/100g and 0.230mg/100g Iron), (0.250mg/100g, 0.110mg/100g and 0.100mg/100g Manganese). The phytochemical screening shows the presence of alkaloids, carbohydrates and proteins in all the samples and the result reveals that processing does not really have effect on phytochemical constituents. The investigation shows that fresh groundnut is a good source of mineral content, while raw and processed groundnut is a good source of some phytochemical constituents and processed groundnut is a good source of protein, fat, and carbohydrate with high nutritional value.
