Abstract:
Three new glucosides of hydroquinone, monoterpene, and megastigmane, benzyl 2,5-dihydroxybenzoate 5-O-β-d-glucopyranoside (isotrichocarpin, 1), (2S,3R)-3,7-dimethyl-6-octene-1,2,3-triol 2-O-β-d-glucopyranoside (leontopodioside D, 4), and (6R,7R,8R,9S)-6,9-epoxy-7,8-dihydroxymegastigman-4-en-3-one 8-O-β-d-glucopyranoside (leontopodioside E, 7) were isolated from the whole herbs of Leontopodium leontopodioides (Willd.) Beauv. (Asteraceae), along with nebrodenside A (2), pungenin (3), betulalbuside A (5), geranyl O-β-d-glucopyranoside (6), and 3β-hydroxy-β-ionone 3-O-β-d-glucopyranoside (8). Their structure were determined by spectroscopic and chemical methods. All the known compounds were reported from this species for the first time. Compounds 2-6 showed potent in vitro pancreatic lipase inhibitory activity, suggesting their participation in the reductive effect of the herbs on triglyceride absorption.
