[:nl]The active ingredients of YM include polyphenols and caffeoyl derivatives (caffeic acid, chlorogenic acid, 3, 4-Dicaffeoylquinic acid, 4, 5-Dicaffeoylquinic acid and 3,5-Dicaffeoylquinic acid), phytosterols and saponins[1, 2].

These active ingredients have been suggested to explain several biomedical properties associated with YM ingestion including anti-oxidant, vasodilatory, lipid lowering properties, anti-mutagenic and anti-glycation effects[3].

These properties have often accompanied weight and fat loss and increased energy metabolism as recently demonstrated in mice studies[4, 5, 6, 7].[:]
