- Abstract:
- ... The lipid composition of soft tissues of the Far-East bivalve mollusk Spisula sachalinensis was studied. Differences in the contents of individual lipid components, i.e., free and bound lipids including neutral lipids, sterols, glyceroglyco- and phospholipids, and cholesterol and its esters, were found. Bound lipids made up 84.2–90% of the lipid mass and were the major component of all soft tissue ...

- Abstract:
- ... Phytochemical investigation of the ethanol extract from the rhizomes of Paris polyphylla var. yunnanensis led to the isolation of three steroid saponins (1–3) and two triterpenoid saponins (4, 5). Among them, compound 1 is a new steroid saponin, and 3–5 were obtained for the first time from the genus Paris. Their structures were elucidated on the basis of extensive analyses of spectroscopic data i ...
