In addition to two known compounds, 5,4'-di-O-methylalpinumisoflavone and cajanin, a new 3-phenylcoumarin metabolite, named indicanine B, and a new isoflavone derivative, named indicanine C, were isolated from the root bark of Erythrina indica. By means of spectroscopic analysis, the structures of the new compounds were characterized as 4-hydroxy-3-(4'-hydroxyphenyl)-5-methoxy-2",2"-dimethylpyrano [5",6":6,7] coumarin and 4'-hydroxy-5-methoxy-2",2"-dimethylpyrano [5",6":6,7] isoflavone… Expand

Bioactive constituents from the stems of Dalbergia parviflora.
From the stems of Dalbergia parviflora, three known flavonoids, six known isoflavonoids, a new isoflavone, dalparvone (2) and a new cinnamyl derivative, dalparvinene (6) were isolated andExpand
Anti-proliferative and anti-inflammatory prenylated isoflavones and coumaronochromones from the fruits of Ficus altissima.
TLDR
The phytochemical investigation of the fruits of F. altissima in this study could provide the evidence for the discovery of lead compounds in the tropics and subtropics of South and Southeast Asia. Expand
Flavonoids and isoflavonoids from Sophorae Flos improve glucose uptake in vitro.
TLDR
Findings demonstrate a potential to develop these flavonoids and isoflavonoids as hypoglycemic drugs, and Stimulating glucose uptake into peripheral cells may be responsible for reducing the level of blood glucose in the circulation. Expand
Coumarins and Related Compounds from the Medicinal Plants of Africa
TLDR
This chapter gives an overview of the isolation, structural features, and pharmacological actions of variety of coumarins produced by the African plants. Expand
Bioactive non-alkaloidal constituents from the genus Erythrina
TLDR
The survey showed furthermore that certain structural features were essential for certain activities and also that compounds that were found active were usually effective against not just one but several disease functions, since most used drugs especially antibiotics tend to produce resistance to certain strains of organisms.
