The content of secondary metabolites in the rhizome Curcuma genus such as Black turmeric (Curcuma aeruginosa Roxb.), White zedoaria (Christm.) Roscoe) and Java xanthorrhiza Roxb.) play a role various pharmacological activities. One them is curcuminoid compounds which have been proved to antibacterial activity. This study aims screen metabolite compounds, determine verify activity extracts Roxb....

A new species of the Stegana (Steganina) ornatipes species group (Diptera: Drosophilidae) is described from Hainan, China, S. (S.) xipengi sp. nov. Based on the mitochondrial ND2 and COI gene sequences, the relationships among eight species from mainland China of the ornatipes group, and their relationships to the undulata, nigrolimbata and shirozui species groups of the same subgenus, are inve...

Parasitic infection can modify host mobility and consequently their dispersal capacity. We experimentally investigated this idea using the ciliate Paramecium caudatum and its bacterial parasite Holospora undulata. We compared the short-distance dispersal of infected and uninfected populations in interconnected microcosms. Infection reduced the proportion of hosts dispersing, with levels differi...

Boswellia serrata (Salai Guggal) is one of the most ancient and respected herbs in Ayurveda. “Gajabhakshya” a Sanskrit name sometimes used for Boswellia suggests that elephants enjoy this herb as a part of their diet. Historically Boswellia serrata is recommended for osteoarthritis, juvenile rheumatoid arthritis, soft tissue fibrosis and spondilytis without any side effect. Present review focus...

Three new prenylated 2-arylbenzofurans - artolakoochol, 4-hydroxy-artolakoochol and cycloartolakoochol - have been isolated from the root bark of Artocarpus lakoocha Roxb., Their structures were elucidated through analysis of their spectroscopic data, and their antiherpetic potential was evaluated by the plaque reduction assay.

Three monoterpenoid gluco-indole alkaloids, 3beta-isodihydrocadambine, cadambine, and 3alpha-dihydrocadambine, were isolated from Nauclea cadamba ROXB. growing in Thailand. The stereochemistry at C19 in 3beta-isodihydrocadambine was elucidated to be R by spectroscopic analysis. Treatment of 3alpha-dihydrocadambine with beta-glucosidase in aqueous ammonium acetate solution gave an indolopyridine...

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.
