CHEMICAL AND BIOLOGICAL STUDIES OF RUSSELIA EQUISETIFORMIS (SCH.&CHAM.) AERIAL PARTS

Abstract

From the aerial parts of Russelia equisetiformis, eight compounds were isolated (1—8) and identified by different spectral techniques as well as comparison with reported data or authentic samples. The isolated compounds included an alkane (n-pentatriacontane) (1), a mixture of β-sitosterol and stigmasterol (2), a triterpene (lupeol) (3), a mixture of β-sitosterol- and stigmasterol-1-O-β-D-glucopyranosides (4), a phenylpropanoidglucoside (4-Allyl-2,6-dimethoxyphenol-1-O-β-D-glucopyranoside(5), a flavonoid (vitexin) (6) and the two closely related phenylethanoids (acteoside) (7) and isoacteoside (8).
