Previously, various steroidal glycosides were reported from plants of Cestrum species.
However, phytochemical investigation has not been conducted on Cestrum newellii. A …

Phytochemical analyses have been carried out on the fresh bulbs of Ornithogalum
thyrsoides with particular attention to the steroidal glycoside constituents, resulting in the …

Two natural steroidal glycosides, diosgenin 3-O-α-l-rhamnopyranosyl-(1→ 2)-[β-d-
glucopyranosyl-(1→ 4)]-β-d-glucopyranoside (1) and laxogenin 3-O-α-l-rhamnopyranosyl …

Further studies by means of preparative HPLC led to the isolation of two new furostanol
saponins, macrostemonosides G (1) and I (3), along with an artifact, macrostemonoside H …

As mentioned above, although the sugar linkage was deduced based on the 13C-NMR
data, it was additionally verified based on the HMBC spectrum. That is, correlations were …
