Coumaroyl triterpene lactone, phenolic and naphthalene glycoside from stem bark of Diospyros angustifolia

Three new compounds, a coumaroyl triterpene lactone ( 1), a phenolic glycoside ( 2) and a naphthelene glycoside ( 3) along with five known compounds ( 4– 8) were isolated from stem bark of Diospyros angustifolia. From the ethanolic extract of stem bark of D. angustifolia three new compounds, a couma...

Description
Summary:Three new compounds, a coumaroyl triterpene lactone ( 1), a phenolic glycoside ( 2) and a naphthelene glycoside ( 3) along with five known compounds ( 4– 8) were isolated from stem bark of Diospyros angustifolia. From the ethanolic extract of stem bark of D. angustifolia three new compounds, a coumaroyl triterpene lactone, diospyrosooleanolide ( 1), a phenolic glycoside, diospyrososide ( 2) and a naphthalene glycoside, diospyrosonaphthoside ( 3) were isolated along with five known compounds ( 4–8). The structures of these compounds were established on the basis of spectroscopic and chemical evidences.
