Possible antitumor promoters in Spinacia oleracea (spinach) and comparison of their contents among cultivars

Biosci Biotechnol Biochem. 2002 Feb;66(2):248-54. doi: 10.1271/bbb.66.248.

Abstract

Spinach leaves were found to contain two potent antitumor promoters as detected by the activity against tumor promoter-induced Epstein-Barr virus activation. The active components were identified as 1-O-alpha-linolenoyl-2-O-(7Z,10Z,13Z)-hexadecatrienoyl-3-O-beta-D-galactopyranosyl-sn-glycerol and 1,2-di-O-alpha-linolenoyl-3-O-beta-D-galactopyranosyl-sn-glycerol by spectroscopic data and some chemical and enzymatic reactions. Their contents significantly varied with the cultivar and with the culture conditions.
