| Abstract | ||
| The phytochemical investigation of the leaves of Cassia notabilis Randell. revealed the isolation of two new glycosides, identified as 6-methoxyapigenin-4`-methyl ether 7- O-α-L-rhamnopyranoside-8-C-β-D-glucopyranoside (1) and 1,7,8-trihydroxyanthraquinone 3-O-β -D-glucopyranoside (7), along with apigenin 7-O- β-D-glucpyranosyl-(1→6)-β-D-glucopyranoside (2), acacetin 7- O-α-L-rhamnopyranoside (3), luteolin 7-O- β-D-glucpyranosyl-(1→6)-β-D-glucopyranoside (4), luteolin 7-O- β-D-glucpyranoside (5), diosmetin 7- O-α-L-rhamnopyranoside (6). The structures of the isolated compounds were established by chromatographic and spectroscopic evidences. Pharmacological studies showed that the three doses of 70% aqueous methanolic extract of C. notabilis leaves (125, 250 and 500 mg/kg) have antidiabetic, analgesic, anti-inflammatory and antioxidant activity. | ||
