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-α-linolenoyl-2-O-(7Z,10Z,13Z)-hexadecatrienoyl-3- O-β-D-galactopyranosyl-sn-glycerol and 1,2-di-O-α-linolenoyl-3-O-β-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.
