A New Flavonoid and other Two Flavonoids Isolated from Different Plant Parts of Selected Cassia Species

Cassia species have been of keen interest in phytochemical and pharmacological research due to their excellent medicinal values. Different classes of natural products, possessing potent physiological and pharmacological activities have been isolated from Cassia species, and they include anthracene derivatives, flavonoids and polysaccharides. Present study shows that various concentration of flavonoids in different plant parts of selected Cassia species. The higher levels of both kaempferol and qurecetin(F+B) were measured in flowers of Cassia nodosa (quercetin: 1.02 mg/gdw; kaempferol: 0.93 mg/gdw). Similarly higher levels of kaempferol-7-O-glucoside(F+B) was also measured in flowers of C. nodosa (0.42 mg/gdw) while minimum levels of kaempferol and qurecetin were measured in root of Cassia renigera (0.07 mg/gdw; 0.06 mg/gdw) respectively. The minimum levels of Kaempferol-7-O-glucoside was not measured in C. renigera.
