Investigation on the anthelminthic bioactive compounds of the ethanol extract of Tadehagi triquetrum resulted in the isolation of three new prenylated isoflavones, triquetrumones A (1), B (2), and C (3), and one new prenylated biisoflavanone, (R)-triquetrumone D (4), along with 16 known compounds, cyclokievitone (5), yukovanol (6), aromadendrin (7), kaempferol (8), astragalin (9), 2-O-methyl-L-chiro-inositol (10), galactitol (11), p-hydroxycinnamic acid (12), ursolic acid (13), betulinic acid (14), β-sitosterol (15), daucosterol (16), stigmasterol (17), stigmasta-5,22-dien-3-O-β-D- glucopyranoside (18), saccharose (19), and docosanoic acid (20). The structures of 1-4 were elucidated on the basis of spectroscopic and spectrometric methods. Compounds 1-3 displayed mild anthelminthic bioactivity, and compound 3 showed a significant binding ability to the estrogen receptor.
