berchemia polyphylla/flavonoid

Five new prenylated flavonoids (1-5) were isolated from the root bark of Berchemia discolor, collected in Tanzania, along with 10 known compounds, by bioactivity-guided fractionation. The structures of compounds 1-5 were elucidated using various spectroscopic techniques. Of these isolates, compound

Investigations were performed on the determination of the main components in Berchemia lineata (L.) DC. (BL) and its metabolism with human liver microsomes (HLM). A total of 35 compounds were detected in BL extracts and 25 of them including 6 naphthopyrones, 10 flavonoids, 2 phenolic acids, 2

Two new alpha-tetralone (=3,4-dihydronaphthalen-1(2H)-one) derivatives, berchemiaside A and B (1 and 2, resp.), and one new flavonoid, quercetin-3-O-(2-acetyl-alpha-L-arabinofuranoside (3), together with ten known flavonoids compounds, eriodictyol (4), aromadendrin (5), trans-dihydroquercetin (6),

To study the chemical constituents from the root of Berchemia lineata (L.) DC., nine compounds were isolated from the EtOAc extract by using silica gel, RP-C18 silica gel column chromatography and preparative HPLC. Based on the spectroscopic analysis, their structures were identified as

Three compounds in a new class of 2-acetoxy-ω-phenylpentaene fatty acid triglycosides, berchemiosides A-C (1-3), and a biosynthetically related phenolic glycoside (4) were isolated from the unripe fruits of Berchemia berchemiifolia, along with three flavonoid 5-O-diglycosides (5-7) and three known
