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

Dengue is an endemic disease with a high incidence in almost all Southeast Asian countries, including Indonesia. This infectious disease is caused by a virus transmitted by the bite of Aedes aegypti mosquito as the main vector. Effective mosquito vector control is a crucial step in stopping the spread of this virus. Of the several methods available, the use of larvicides is considered one of the most successful treatments in reducing the number of mosquito vectors. However, widely used synthetic larvicides can have undesirable side effects on the environment and non-target organisms including human health. The aim of this study was to discover a new biolarvicide from natural materials that is relatively safer. In this study, the biolarvicidal activity of mangrove plant species that are commonly found in Ngurah Rai Mangrove Forest Bali was tested, namely Sonneratia alba. Mangrove root simplicia was extracted by reflux method using three different solvents namely methanol, chloroform, and n-hexane. The content of compounds in the extract were analyzed using GC/MS method. The larvicidal activity of the extracts were tested on A. aegypti instar III/IV larvae with concentrations of 0.1, 1, 10, 100, and 1000 ppm for 24 hours. Subsequently, the average value of larval mortality was used to calculate the LC50 of each extract. The results showed that S. alba methanol extract provided the best larvicidal activity compared to chloroform and n-hexane extracts, with mortality of 69.33% at a concentration of 1000 ppm and LC50 of 1265 ppm. GC-MS analysis showed that the methanol extract of S. alba contained five dominant compounds namely Methyl 2-hydroxy-eicosanoate (19.55%); 4H-1-Benzopyran-4-one, 3,5-dihydroxy-2-(4-hydroxy-3-methoxyphenyl)-7-methoxy (16.48%); 4-((1E)-3-Hydroxy-1-propenyl)-2-methoxyphenol (10.06%); Benzamide, N-[4-(2-naphtyl)-2-thiazolyl]- (9.40%); and 2,3-Dihydro-3,5-bis(3-methoxyphenyl)-1H-inden-1-one (6.52%). The results of this study provide a preliminary result on larvicide activity from mangrove S. alba in order to develop bio larvicides from nature which is safer for human health and environment.

Abstract

Mangroves are plants that contain various secondary metabolites with various potential pharmacological activities, one of which is cytotoxic activity. However, researchers have not extensively explored the evidence of secondary metabolite compounds and their toxicity effects in mangrove plants. This research aims to determine the content of secondary metabolite compounds and the toxicity of the leaf extract of the Sonneratia alba mangrove plant in the Ngurah Rai Grand Forest Park (TAHURA), Bali. In this experimental research, compound extraction was carried out using a maceration technique for 2x24 hours using two types of solvents, namely methanol and n-hexane. Phytochemical tests were carried out using qualitative methods and gas chromatography-mass spectrometry (GC-MS), while the toxicity test used was the brine shrimp lethality test (BSLT) method. Potassium dichromate and sea water without extract were used as positive and negative controls, respectively. The LC50 value was calculated using probit analysis in Microsoft Excel. Phytochemical test results showed that the methanol extract contains phenol, saponin, tannin, and steroid compounds. Meanwhile, n-hexane extract only contains steroid compounds. GC-MS analysis showed that the compounds with the largest area percentages in the methanol and n-hexane extracts were 1,2,3-benzenetriol (3.94%) and n-hexadecenoic acid (2.41%), respectively. Based on the LC50 value, the methanol extract of S. alba mangrove leaves was moderately toxic (178.17 ppm), while the n-hexane extract was weakly toxic (567.23 ppm). The results of this study provide information that the type of chemical solvent has a major influence on the level of toxicity of S. alba leaf extract, with polar methanol solvent providing the highest toxicity effect compared to nonpolar n-hexane solvent.

Abstract

The emergence of antibiotic resistance as one of the global public health threats makes research on new antibacterial compounds urgently needed. Among natural resources, the Impatiens balsamina plant has the potential to be explored as the new source of antibacterial agents. This study aimed to identify the phytochemical composition and evaluate the antibacterial activity of I. balsamina leaf extracts against Gram-positive and Gram-negative bacteria. Extracts were prepared using the maceration method with methanol, chloroform, and n-hexane solvents at a 1:5 sample-to-solvent ratio. Phytochemical screening was performed qualitatively, and antibacterial activity was evaluated using the disc diffusion assay. Analysis of methanol extract detected the presence of flavonoids, saponins, tannins, phenols, steroids, and glycosides, while chloroform extract consisted of tannins, phenols, and steroids. On the other hand, steroids were the only compounds detected qualitatively in n-hexane extract. Antibacterial testing revealed that methanol extract exhibited the highest activity, with zones of inhibition (ZOI) of 15.10±0.18 mm, 9.40±0.30 mm, 14.75±1.28 mm, and 8.67±0.50 mm against Streptococcus mutans FNCC 0405, Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Klebsiella pneumoniae ATCC 700603, respectively. A concentration-dependent ZOI was observed in the methanol extract, with activity increasing at higher concentrations. GC-MS analysis of the methanol extract identified 32 compounds, including n-hexadecanoic acid (12.12%), 2-acetylbenzoic acid (8.26%), 5-hydroxymethylfurfural (8.21%), and 2-methoxy-4-vinylphenol (4.67%), which are known to possess antimicrobial, antioxidant, and anti-inflammatory activities. Chloroform extract showed moderate activity against S. mutans (7.04±0.15 mm) and S. aureus (7.10±0.31 mm), while n-hexane extract exhibited no antibacterial activity. The significant antibacterial activity of methanol extract is likely due to its rich phytochemical composition, highlighting methanol as an effective solvent for extracting bioactive compounds. These findings provide a strong foundation for further exploration of I. balsamina leaf extracts as a source of antibacterial agents.
