Violanthin is a member of the class of compounds known as flavonoid 8-c-glycosides. Flavonoid 8-c-glycosides are compounds containing a carbohydrate moiety which is C-glycosidically linked to 8-position of a 2-phenylchromen-4-one flavonoid backbone. Violanthin is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Violanthin can be found in rice, which makes violanthin a potential biomarker for the consumption of this food product. Violanthin is isolated from the stems of Dendrobium officinale, has potent antioxidant and antibacterial activities. Violanthin inhibits acetylcholinesterase (AChE) with an IC50 value of 79.80 μM[1].

Epi-alpha-amyrin, also known as epi-α-amyrin, is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Epi-alpha-amyrin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Epi-alpha-amyrin can be found in herbs and spices, pomes, and rosemary, which makes epi-alpha-amyrin a potential biomarker for the consumption of these food products.
