Flavonoids from Anemone tomentosa roots
The genus Anemone (Ranunculaceae) comprises about 150 species, of which 52 are distributed in northern China. As triterpenoid saponins are the main effective components of the genus Anemone, it has extensive biological activities, such as antitumor, antibacterial, and insect antifeeding properties. Anemone tomentosa (Maxim.) Pei is a perennial herb that is commonly called “Da Huo Cao” in China . Its roots have been used as traditional Chinese medicine for the treatment of dysentery, malaria, infantile malnutrition, carbuncles, etc. . Previous phytochemical studies of A. tomentosa have led to the isolation of coumarins , triterpenoids, and sterols [4, 5], but there are no records of the flavonoid constituents. Herein we communicate the additional isolation and structural elucidation of eight known flavonoids 1–8, of which 1, 4, and 6 were isolated from plants of the genus Anemone for the first time. Flavonoids were found first in A. tomentosa.
