Phytochemistry of genus Gentiana , XXIV. New C‐glycosylflavones from the leaves of Gentiana asclepiadea L. p ‐Hydroxybenzoyl‐2″‐isoorientin‐4′‐ O ‐β‐D‐glucoside ( 1 ) was isolated from the leaves of Gentiana asclepiadea L. by means of column chromatography. This is the first occurrence in nature of a p ‐hydroxybenzoate of isoorientin. p ‐Hydroxybenzoyl‐2″‐isoorientin ( 2 ) was also shown to be present in the same plant.
