the roots of Aletris farinosa that possesses an unusual malonate half-ester functional group …

A series of novel sesterterpenes (2–6) have been isolated from the roots of Aletris farinosa
and structurally characterized by MS, NMR, and X-ray crystallography in conjunction with …

The absolute stereochemistry of the steroidal saponins bethosides B and C was previously
assigned as (22 R, 25 R) on the basis of work that employed Horeau's method. Our studies …

Abstract Six new cholestane glycosides (1, 5, 6, 10, 12, and 13) and two new sterols (9 and
11), along with five known compounds (2–4, 7, and 8), were isolated from the underground …

The major phytochemical constituents of the widely used medicinal herb Chamaelirium
