Biochemical Studies on Pollen: Part V. Flavonoid Pigments from Pollen of Lilium lancifolium Thunb

Abstract

Crystalline flavonoid pigments I and II were isolated from the pollen of Lilium lancifolium Thunb. in the yields of 0.056% and 0.036%, respectively. Melting points, color reactions, RF values on paper chromatogram, UV and IR spectra of the pigments I and II were similar to those of authentic rutin and narcissin, respectively. On hydrolysis with sulfuric acid, glucose and rhamnose were detected from both pigments, while quercetin was isolated from the pigment I and isorhamnetin from the pigment II. Therefore, the pigments I and II were confirmed to be rutin (quercetin-3-rutinoside) and narcissin (isorhamnetin-3-rutinoside), respectively. © 1966, Japan Society for Bioscience, Biotechnology, and Agrochemistry.
