A detailed chemical study on the stem bark of Garcinia nitida has led to the isolation of five xanthones. They are 1,6-dihydroxy-5-methoxy-6,6-dimethylpyrano[2',3':2,3]-xanthone (1), inophyllin B (2), osajaxanthone (3), 3-isomangostin (4) and rubraxanthone (5). The structures of these compounds were established using mainly 1-D and 2-D NMR spectroscopy ((1)H, (13)C, DEPT, COSY, HMBC and HMQC) w...

Tetraoxygenated xanthones, cowaxanthones A-E, together with 10 previously reported tetraoxygenated xanthones, were isolated from the crude hexane extract of the fruits of Garcinia cowa. Cowaxanthone B has previously been reported as a synthetic xanthone. Their structures were elucidated by analysis of spectroscopic data, especially by 1D and 2D NMR. The antibacterial activities of the isolated ...

A new flavanone-chromone biflavonoid, preussianone (1), has been isolated from the leaves of Garcinia preussii, along with four known biflavonoids. The absolute stereostructures were elucidated by chemical, spectroscopic, and chiroptical methods. The biological properties of the new biflavonoid against several bacterial strains were evaluated.

Mangosteen (Garcinia mangostana L.) has exceptional potential for commercial and pharmaceutical applications due to its delicious fruit and medicinal properties. Nevertheless, the molecular mechanism of mangosteen seed development is poorly understood. In this study, we performed transcriptomic analysis of four seed developmental stages; eight, ten, twelve and fourteen weeks after anthesis. Ill...

OBJECTIVE To assess the neuroprotective effects of aqueous extract of Garcinia kola on neurotoxin administered malnourished mice adopting histological procedure. METHODS The study was carried out using thirty-two adult malnourished mice which were randomly assigned into four groups (n=8): A, B, C and D. Group A served as control, while the other groups served as the experimental groups. Anima...

Commercial dietary supplements are marketed as a panacea for the morbidly obese seeking sustainable weight-loss. Unfortunately, many claims cited by supplements are unsupported and inadequately regulated. Most concerning, however, are the associated harmful side effects, often unrecognized by consumers. Garcinia cambogia extract and Garcinia cambogia containing products are some of the most pop...

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 undertaken to establish the diuretic activity of ethanol and aqueous extract of dried leaves of Garcinia cambogia in rats. Aqueous and ethanol extracts of leaves were administered to experimental rats orally at doses of 100 and 200 mg/kg and compared with furosemide (20 mg/kg, intraperitoneally) as the standard. The parameters measured for diuretic activity were total urin...
