Kanno M, Shibano T, Takido M, Kitanaka S
Antiallergic agent from natural sources. 2. Structures and leukotriene release-inhibitory effect of torososide B and torosachrysone 8-O-6"-malonyl β-gentiobioside from Cassia torosa Cav.
Chemical and Pharmaceutical Bulletin 47(7) (1999)
915-918
Two new anti-allergic compounds, torososide B and torosachrysone 8-O-6"-malonyl gentiobioside were isolated from the seeds of Cassia torosa Cav., and their structures were established as physcion 8-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl-(1→3)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranoside and torosachrysone 8-O-β-D-glucopyranosyl-(1→6)-6-malonyl β-D-glucopyranoside on the basis of spectral and chemical evidence. Torososide B and torosachrysone 8-O-6"-malonyl gentiobioside were found to inhibit the release of leucotrienes from rat peritoneal mast cells induced by calcium ionophore A 23187.

Kitanaka S, Takido M
Studies on the constituents of the leaves of Cassia torosa Cav. III. The structures of two new flavone glycosides
Chemical and Pharmaceutical Bulletin 40(1) (1992)
249-251
Two new flavone glycosides were isolated along with diosmetin, luteolin, and luteolin 7-O-glucoside, from the leaves of Cassia torosa CAV., and their structures were established as diosmetin 3'-O-β-D-glucopyranoside (1) and torosaflavone B 3'-O-β-D-glucopyranoside (2) (diosmetin 6-C-β-D-oliopyranosyl-3'-O-β-D-glucopyranoside) on the basis of spectroscopic and chemical evidence.
