Conjugated Serotonins Related to Cathartic Activity in Safflower Seeds (Carthamus tinctorius L.)

Abstract

Recent studies on the isolation of cathartic lignan glycoside1) from Carthamus tinctorius L. prompt us to report our results in a related area. Ethyl acetate extracts from oil-free saf flower meal (3 kg) were chromatographed on silica gel columns to give three new serotonin derivatives 1 (2.22 g), 2 (1.32 g) and 3 (0.55 g), all of which showed positive response for the both Folin-Ciocaltheu's and Ehrlich's reagents. © 1978, Japan Society for Bioscience, Biotechnology, and Agrochemistry.
