Abstract

East Kalimantan is one of the areas that have the potential for various traditional medicinal plants. Melastoma malabathricum (known locally as karamunting, senduduk) is an invasive plant in the family of Melastomataceae with a potential medicinal plant. This study explored the potential of twigs and stem bark of Karamunting (Melastoma malabathricum) for its antioxidant and antibacterial activity. The twigs and stem bark of Karamunting were macerated to yield ethanolic extract. The phytochemical screening was evaluated by Harborne and Kokate methods. Antioxidant activity was evaluated by DPPH radical scavenging assay. Antibacterial activity was examined using agar well diffusion method against Propionibacterium acnes. The results showed that the ethanol extracts of twigs and stem bark samples display an ability to inhibit DPPH free radical by 82% and 88% at 50 ppm concentration. Antibacterial activity of the twigs and stem bark samples showed potent activity to inhibit the P. acnes growth with 11.3 mm and 11 mm inhibition activity. Based on the results, the twigs and stem bark of M. malabathricum plants display potential as a natural antioxidant and antibacterial agent.

Abstract

The Pecut kuda plant is one of the plants of the genus Stachytarpheta which is found in tropical regions, including Indonesia. In Indonesia this plant is found in East Kalimantan which grows wild. This study aims to determine the type of secondary metabolites and the level of toxicity of the leaves of horse whip (Stachytarpheta jamaicenesis (L.) Vahl). The research stages were sample drying, sample maceration, filtered, concentrated with a rotary evaporator, phytochemical and toxicity tests using linear regression values to determine the LC50 value with SAS probit analysis. Phytochemical test results showed that the pecut horse leaf extract in the n-hexane fraction contained flavonoids, quinones and steroids, the ethyl acetate fraction contained alkaloids, steroids, saponins, flavonoids and quinones and the methanol fraction contained phenolic flavonoids, quinones and saponins. The results of the toxicity test on Artemia salina L. shrimp larvae in the fraction of n-hexane, ethyl acetate and methanol obtained LC50 values of 0.036 ppm, 5.24 ppm and 29.51 ppm, respectively. Based on the LC50 value, it can be concluded that the three fractions are very toxic, but the most toxic is the n-hexane fraction (LC50 = 0.036 ppm).

Abstract

Antioxidant activity, total phenolic and total flavonoid contents of some traditional medicinal plants grown in East Kalimantan, Indonesia, were investigated. Plant sample are Macaranga gigantea leaf, Ceiba pentandra leaf, Ceiba pentandra bark, Blumea balsamifera leaf and Artocarpus altilis leaf. Natural antioxidants from plant species are considered safe. Therefore, people are now more interest in finding out the treatment through natural remedies. The plant's total phenolic content was determined by the Folin-Ciocalteu method, while total flavonoid content was determined by the Colorimetric assay method. Antioxidant activity was evaluated by DPPH radical scavenging assay. The results showed that plant samples tested contained 22.02 to 214.88 µg of gallic acid equivalents (GAE)/mg extract represented the total phenolic content. The flavonoid content of the samples was in range from 50.00 to 896.67 µg of catechin equivalents (CE)/mg extract. The plant samples displayed ability to inhibit DPPH free radical formation by 59-81% at 50 ppm concentration. These finding suggest that these plants could possess natural antioxidants and give a scientific basis to the traditional uses of the investigated plants.

Abstract

Calamus ornatus Bl., locally known as rotan mantang or rotan seuti is one of the commercial rattan species growing in the forests of East Borneo. Its fruit is edible, like the fruits of other species of rattan, and it has been used by the local people as traditional medicine to treat stomachache or toothache. Until recently, there has not been any study investigating the benefits of the fruit for medicinal or other purposes. This research aimed to discover the bio-activity potentials of Calamus ornatus Bl. fruits by identifying its toxicity level and antibacterial potentials. The parts of the fruit (pericarp, flesh, and seed) were extracted using ethanol as solvent to extract samples. The toxicity was analyzed by using the Brine Shrimp Lethality Test (BSLT) method while the antibacterial activity was tested using a well diffusion method. Low toxicity was found in the flesh, whereas the pericarp and the seed were non-toxic. Antibacterial activity against Escherichia coli was found in the pericarp and the seed, while antibacterial activity against Streptococcus mutans was found in the pericarp and the flesh.

Abstract

The aim of this study was to evaluate the antibacterial activity of ethanol concoction (mixed extract) of three herbs plants, such as: Boesenbergia pandurata, Solanum ferox and Zingimber zerumbet against Aeromonas hydrophila, Pseudomonas sp. and both bacteria. The Plant extracts were obtained by using ethanol and the concentration of the extract was 600 mgL-1 of B. pandurata, 900 mgL-1 of S. ferox and 200 mgL-1 of Z. zerumbet. The inhibition zone was measured after 6, 12, 18, 24 h incubation at 30o C. The ratios of concoction S. ferox and B. pandurata (for 100 mL solution) were 90:10; 80:20; 70:30; 60:40; 50:50; 40:60; 30:70; 20:80; 10:90. The same ratios were made on the concoction of S. ferox and Z. zerumbet. The concoctions of S. ferox and B. pandurata in the ratio of 50:50 and 60:40, and the concoction of S. ferox and Z. Zerumbet with ratio 60:40 had higher antibacterial activity against A. hydrophila single isolate compared to the other concoctions. Furthermore, the concoction extract of S. ferox and B. pandurate 50:50 and the combined of S. ferox and Z. zerumbet ratio 50:50 and 90:10 were the best combination to inhibit the growth of a single bacterium Pseudomonas sp. The combined S. ferox and B. pandurata ratio 50:50; 10:90 and S. ferox mixed with Z. zerumbet ratio 50:50 and 40:60 were the best combination against the combined bacteria between A. hydrophila and Pseudomonas sp. The conclusion of this research was the combined extract of S. ferox and B. pandurata and S. ferox with Z. zerumbet are effective to suppress the growth of single or combination of A. hydropila and Pseudomonas sp.

Abstract

This research evaluated a method involving provision of a concoction of Boesenbergia pandurata, Solanum ferox dan Zingimber zerumbet extracts for pathogen prevention in tilapia. The concentration of each extract was 600 ppm of Boesenbergia pandurata/BP, 900 ppm of Solanum ferox/SF and 200 ppm of Zingimber zerumbet/ZZ. The examination was performed by issuing two combinations of extracts (SF:BP, SF:ZZ) against Aeromonas hydrophila and Pseudomonas fluorescens (105 CFUmL-1). Preventive trials were carried out by providing a concoction of extracts through intraperitoneal injection (0.1 mL/fish) in tilapia (15±2 g) and the immersion method was performed by bathing the fish in the extracts for 20 minutes, with pathogen challenging during the following 24 h being carried out. The composition of the used extract was by SF60:ZZ40; SF50:ZZ50; BP90:SF10; BP50:SF50; and fish without being given the extract. Haematology and immunology parameters were observed at the 4th week after challanges with pathogenic bacteria. The number of white blood cells (WBCs) increased significantly (P <0.05) compared to controls without extract, with a similar increase observed for red blood cell (RBCs), but heamatocrit (Ht) and hemoglobin (Hb) values did not significantly increase compared to control. Phagocytic index, respiratory burst and lysozyme activities also experienced a significant increase in fish fed with combined extracts compared to controls. The numbers of pathogenic bacteria in the body of the fish given extract were also lower than the control and significantly different at the 4th week. The results of this study indicate that giving combined extracts of SF50:ZZ50 and BP90:SF10 provides the best protection (RPS) against infection of A. hydrophila and P. fluorescent by injection of 100%. This study indicates that providing combined extracts by injection and immersion in the ratio of SF50:ZZ50 has a positive effect in increasing the non-specific immune system of tilapia and increasing protection against bacterial infections.
