Hence, collectively, our results indicated that anticancer potency of GSE obtained from XIAMEN exhibits some differences from other previous reported studies (using different GSE cultivars), that cannot be explained only in terms of their relative epigallocatechin or procyanidin content, and other compounds seemingly can enhance (or even interfere with) the anticancer effects exerted by GSE (Dinicola et al.
Active ingredients found in hawthorn include tannins, flavonoids (such as vitexin, rutin, quercetin, and hyperoside), oligomeric proanthocyanidins (OPCs, such as epicatechin, procyanidin, and particularly procyanidin B-2), flavone-C, triterpene acids (such ursolic acid, oleanolic acid, and crataegolic acid), and phenolic acids (such as caffeic acid, chlorogenic acid, and related phenolcarboxylic acids) [40,38].
