Propionibacterium acnes and Staphylococcus epidermidis have been recognized as pus-forming bacteria triggering an inflammation in acne. The present study was conducted to evaluate antimicrobial activities of Thai medicinal plants against these etiologic agents of acne vulgaris. Crude extracts were tested for antimicrobial activities by disc diffusion and broth dilution methods. The results from...

The present study was designed to evaluate antiosteoporotic activity of the fresh juice mixtures obtained from Actinidia deliciosa and Garcinia mangostana as well as the pericarp extract of Garcinia mangostana on postmenopausal osteoporosis. 3-month-old female Wistar rats were ovariectiomized and the treatment began 14 days after ovariectomy and continued for 40 days. Statistically significant ...

Garcinia mangostana L. (Mangosteen), of the family Clusiaceae, is one of the economically important tropical fruits in Indonesia. In the present study, we performed de novo transcriptomic analysis of Garcinia mangostana L. through RNA-Seq technology. We obtained the raw data from 12 libraries through Ion Proton System. Clean reads of 191,735,809 were obtained from 307,634,890 raw reads. The raw...

The present study was aimed to investigate the activity of Thai medicinal plants on inflammation caused by Propionibacterium acnes in terms of free radical scavenging and cytokine reducing properties. P. acnes have been recognized as pus-forming bacteria triggering an inflammation in acne. Antioxidant activity was determined by DPPH scavenging and NBT reduction assay. The result showed that Gar...

From the stem bark hexanic extract of Garcinia chapelieri, chapexanthone A, B were isolated using combinations of column and thin-layer chromatographic methods. Their structures were elucidated by NMR spectroscopic methods, mainly 1D and 2D NMR.

Twelve xanthones were isolated from the hexane extract of the heartwood of Garcinia mangostana from Myanmar. Their structures were determined using 1D and 2D NMR techniques

Garcinia mangostana is a tropical fruit plant rich in antioxidant and bears recalcitrant seeds. The extent of water loss and low temperature tolerable by recalcitrant seed varies from regular orthodox seeds. Present study generates transcriptome resources for G. mangostana to postulate potential transcriptome differences between recalcitrant and orthodox seeds during seed germination process. R...

From the stem bark of Garcinia benthami a new benzophenone, named Salimbenzophenone, was isolated. The structure was determined by means of spectroscopic analysis.

Five xanthones named cowagarcinone A-E and six previously reported xanthones were isolated from the latex of Garcinia cowa Roxb. Their structures were determined on the basis of spectroscopic analysis. The crude latex and the isolated compounds were investigated for their radical scavenging activities.
