Protium is the main genus of the Burseraceae family and one of the most common genera in South America, with an important species called "breu." Gum and oil-resins of this species are used as tonic and stimulant and for the treatment of ulcers and inflammation. The present study aims to isolate and investigate the anti-inflammatory activity of triterpene compounds isolated from oil-resin of Pro...

The resin of Canarium strictum Roxb. is used for rheumatism and asthma; the bark as a mosquito repellent. major compounds in are triterpenoids, but no studies have been performed on bark, this study investigated economically important resource. Ten folk healers were interviewed about their medicinal uses C. strictum. Resin extracted with dichloromethane followed by methanol using accelerated so...

Isolation and GC/MS quantitative determination of ursolic acid in the herb of Nepeta cataria var. citriodora have been performed. The content of this compound was in the range 0.95 ñ 1.30%. Daucosterol (βsitosterol 3-O-β-D-glucoside) was also isolated from the plant, in addition to small amounts of β-sitosterol, campesterol, α-amyrin and β-amyrin. The content and composition of essential oil in...

Platostoma rotundifolium (Briq.) A. J. Paton aerial parts are widely used in Burundi traditional medicine to treat infectious diseases. In order to investigate their probable antibacterial activities, crude extracts from P. rotundifolium were assessed for their bactericidal and anti-virulence properties against an opportunistic bacterial model, Pseudomonas aeruginosa PAO1. Whereas none of the t...

Cirsium arvense (L.) Scop., commonly known as creeping thistle, is a weed of Asteraceae. This study was undertaken to explore various phytoconstituents present in flower this weed. To achieve goal, the dried flowers were soaked methanol for one week and filtered. methanolic extract subjected GC-MS analysis 7 compounds identified. These included olean-12-en-3-ol, acetate, (3β)- (63.87%), lanosta...

The relative distribution of several compounds identified in four samples of recently deposited sediments of the Itacorubi Mangrove located on the Santa Catarina Island, southern Brazil, was compared with similar data on compounds extracted from fresh leaves of three mangrove species (Avicennia schaueriana, the dominant species in the area, Rhizophora mangle and Laguncularia racemosa) and the G...

Euphorbia is a genus of flowering plants belonging to the family Euphorbiaceae. Consisting of 2008 species. The genus Euphorbia produces an irritant, which constitute a health hazard to humans and livestock. The genus Euphorbia is one of the largest and most complex genera of flowering plants, however, several botanists have made unsuccessful attempts to subdivide it to smaller genera.  Many Eu...

Apple (Malus × domestica) accumulates bioactive ursane-, oleanane-, and lupane-type triterpenes in its fruit cuticle, but their biosynthetic pathway is still poorly understood. We used a homology-based approach to identify and functionally characterize two new oxidosqualene cyclases (MdOSC4 and MdOSC5) and one cytochrome P450 (CYP716A175). The gene expression patterns of these enzymes and of pr...
