Cytotoxic Spirostane-Type Saponins from the Roots of Chlorophytum borivilianum

2009

Four new spirostane-type saponins named borivilianosides E-H (1-4) were isolated from an ethanol extract of the roots of Chlorophytum borivilianum together with two known steroid saponins (5 and 6). The structures of 1-4 were elucidated using mainly 2D NMR spectroscopic techniques and mass spectrometry. The cytotoxicity of borivilianosides F (2), G (3), and H (4) and three known compounds was evaluated using two human colon cancer cell lines (HT-29 and HCT 116).

Steroidal saponins from Chlorophytum deistelianum

2016

Abstract Phytochemical investigation of the aerial parts of Chlorophytum deistelianum led to the isolation of four previously undescribed steroidal saponins called chlorodeistelianosides A–D with five known ones. Their structures were established mainly by extensive 1D and 2D NMR spectroscopic techniques and mass spectrometry as (25R)-3β-[(β- d -glucopyranosyl-(1 → 3)-[α- l -rhamnopyranosyl-(1 → 4)]-β- d -xylopyranosyl-(1 → 3)-[β- d -glucopyranosyl-(1 → 2)]-β- d -glucopyranosyl-(1 → 4)-β- d -galactopyranosyl)oxy]-5α-spirostan-12-one, (24S,25S)-24-[(β- d -glucopyranosyl)oxy]-3β-[(β- d -glucopyranosyl-(1 → 2)-[β- d -xylopyranosyl-(1 → 3)]-β- d -glucopyranosyl-(1 → 4)-β- d -galactopyranosyl)ox…

Furostane-Type Steroidal Saponins from the Roots ofChlorophytum borivilianum

2008

Four new furostanol steroid saponins, borivilianosides A–D (1–4, resp.), corresponding to (3β,5α,22R,25R)-26-(β-D-glucopyranosyloxy)-22-hydroxyfurostan-3-yl O-β-D-xylopyranosyl-(13)-O-β-D-glucopyranosyl-(14)-O-[α-L-rhamnopyranosyl-(12)]-β-D-galactopyranoside (1), (3β,5α,22R,25R)- 26-(β-D-glucopyranosyloxy)-22-methoxyfurostan-3-yl O-β-D-xylopyranosyl-(13)-O-β-D-glucopyranosyl-(14)-O-[α-L-rhamnopyranosyl-(12)]-β-D-galactopyranoside (2), (3β,5α,22R,25R)-26-(β-D-glucopyranosyloxy)-22-methoxyfurostan-3-yl O-β-D-xylopyranosyl-(13)-O-[β-D-glucopyranosyl-(12)]-O-β-D-glucopyranosyl-(14)-β-D-galactopyranoside (3), and (3β,5α,25R)-26-(β-D-glucopyranosyloxy)furost-20(22)-en-3-yl O-β-D-xylopyranosyl-(13…
