Study on Flavonoids in Buddleja lindleyana Fruits

To study the flavonoids in the fruits of Buddleja lindleyana.The compounds were separated by repeated silica gel, RP-18 and Sephadex LH-20. Their structures were elucidated on the basis of chemical evidence and spectral data.Five flavonoids were isolated and identified as luteolin (1), tricin (2), acacetin (3), acacetin-7-O-β-D-glucopyranoside (4) and linarin(5).Compounds 3,4 and 5 are isolated from fruits of Buddleja lindleyana for the first time. Compound 2 is isolated from fruits of Buddleja lindleyana for the first time.
