leontopodium sinense/triglyceride

Eight previously undescribed acyl atractyligenin and carboxyatractyligenin glycosides were isolated from whole Antennaria rosea subsp. confinis (Greene) R. J. Bayer (Compositae) [syn. Leontopodium leontopodioides (Willd.) Beauv. (Asteraceae)] plants and their structures were determined by

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

A phytochemical investigation to obtain new triglyceride (TG) accumulation inhibitors resulted in the isolation of six new isobenzofuranones, leontopodiols A (1), B (2), leontopodiosides C (3), D (4), E (5), F (6), together with three known ones (7-9) from the aerial parts of Leontopodium
