The traditional medicine has been used in Indonesia since the days of the Ancient Mataram Kingdom (about 12 centuries ago). Indonesia is rich in medicinal plants. For this reason, it is necessary to inform the broader community regarding medicinal plants in Indonesia that have the potential as antigout. The prevalence of gout in Indonesia is in the range of 1.6-13.6 per 100,000 people and will increase with age. There are 25 species of Indonesian plants that have more than 50\% xanthine oxidase (XO) enzyme inhibitory activity. XO is responsible for catalyzing hypoxanthine to xanthine then producing uric acid, accompanied by the formation of reactive oxygen species (ROS) during catalysis. The magnitude of the inhibitory power to XO ranged from 50.00{\textpm}1.16\% to 97.53\%. The lowest inhibitory power of 50.00{\textpm}1.16\% was in Phaleria macrocarpa, while Orthosiphon aristatus had the highest inhibitory power of 97.53\%. The major compounds that inhibit xanthine oxidase are flavonoids. The structural similarity of flavonoids in rings A and C with xanthine as a substrate causes hydrophobic interactions, hydrogen bonds, and van der Waals forces between flavonoids and XO. It means that flavonoids bind to the XO active site, thereby preventing the formation of uric acid. The type of inhibitory kinetics that occurs between flavonoids and XO is competitive inhibition. Five plants with competitive inhibition kinetics against XO are Sida rhombifolia, Syzygium polyanthum, Cyperus rotundus, Ruellia tuberosa and Phaleria macrocarpa.

Wild edible mushrooms produce a variety of bioactive compounds that are known to have antioxidant properties. Natural antioxidants can protect against oxidative induced free radicals without any side effects. Thus, they are consumed by people for food and nutraceutical values. The purpose of this study was to evaluate the phytochemicals and antioxidant activity of three wild edible termite mushrooms (Termitomyces albuminosus, T. eurhizus and T. robustus). Different phytochemicals were screened in the 50\% ethanol, methanol and water extracts of three termite mushrooms. Total phenolic and flavonoid contents were determined by Folin-Ciocalteau and aluminium chloride method respectively. The antioxidant activity of three termite mushrooms was evaluated by DPPH assay. Qualitative screening of phytochemicals has revealed that alkaloid, steroid, fatty acid, flavonoid, saponin, tannin, carbohydrate and protein are found in the 50\% ethanol, methanol and water extracts of three species of termite mushroom. A high amount of total phenolic and flavonoid content was found in the 50\% ethanol extract of T. albuminosus, T. eurhizus and T. robustus (TPC: 50.28, 54.56 and 57.63 mg GAE/g extract; TFC: 16.30, 18.43 and 18.80 mg QE/g extract respectively). Due to high phenolic and flavonoid content, 50\% ethanol extract of three termite mushrooms has shown high antioxidant activity (i.e., lowest IC50: 710.00 - 714.05 μg/ml). These termite mushrooms have antioxidant properties due to the presence of bioactive secondary metabolites that can potentially be used as a source of natural antioxidants in the form of food and nutraceutical.

Background: Plectranthus scutellarioides is one of medicinal plants in Indonesia, which has several hundred varieties but only one is known by local people as medicine. Objective: Six varieties of Plectranthus scutellarioides were analyzed for their total flavonoid content, chemical compound, and moleculer genetic. Methods: TFCs were analyzed using AlCl3 colorimetric method, chemical compounds were identified using TLC-scanning densitometer, GC-MS, and FTIR, moleculer genetic were observed using DNA barcoding rbcL gene. Results: The TFCs of trailing psycholeus, and flamingo varieties were higher than the other varieties. TLC-scanner densitometer showed that color blaze dark star, trailing psycholeus, and trailing queen had similar profiles, as did beale street, trailing rose, and flamingo. The GCMS results showed notable difference in trailing psycholeus and trailing queen which have 2-oleoylglycerol and 9(E),11(E)-conjugated linoleic acid in larger amounts than others, respectively. Multivariate analysis of the FTIR spectra showed the closeness of all varieties, except for beale street which had the lowest similarity with the others. Despite that, genetic studies using the rbcL gene and comparing the results with the P. scutellarioides gene in the database (MW538954.1) showed beale street was the most similar (99.52\%). The phylogenetic analysis showed that beale street and trailing psycholeus have the highest similarity among others. Conclusions: There is a slight difference in chemical composition between varieties as well as the genetic. Therefore, quality control or standardisation is needed in the use of this plant as a traditional medicine.

Background: HIV continues to be a major global public health issue, having claimed more than 35 million lives so far. In 2016, 1 million people died from HIV-related causes globally. HIV-1 reverse transcriptase is one of HIV{\textquoteright}s vital enzymes for virus reproduction. If the enzyme is inhibited, the virus multiplication could be significantly decreased. There are currently many treatments for HIV, but more effective treatment is always needed because of the possibility of drug resistance and side effects for long-term use. Based on the previous study, there are some natural compounds with high affinity to the HIV-1 reverse transcriptase enzyme. Some of these compounds are flavonoid glycosides. Aims and Method: This study was aimed to learn more about in silico HIV-1 reverse transcriptase inhibitory activities of flavonoid glycosides using docking method. Results: The results showed that the most recommended flavonoid glycosides are those with the lowest binding energy, which were kaempferol-3-O-rhamnoside, myricetin-3-O-rhamnoside and quercetin-3-O-rhamnoside. This was due to the interactions of all three flavonoid rings and sugar moiety with key amino acid residues, which were Leu100, Lys101, Glu138, Tyr181, His235 and Tyr318. Conclusion: Flavonoid glycosides with rhamnose as glycone showed lower binding energy on HIV-1 reverse transcriptase.
