Rebaudioside C belongs to the family of Steviol Glycosides. It is a natural constituent of the plant Stevia rebaudiana Bertoni and used as natural sweeteners to diabetics and others on carbohydrate-controlled diets.

1-O-Acetylbritannilactone has anticancer activity, it suppresses angiogenesis and lung cancer cell growth possibly via regulating the VEGFR-Src-FAK signaling, it also can combine with gemcitabine elicits a potent apoptosis of lung cancer cell. 1-O-Acetylbritannilactone may serve as a novel therapeutic intervention for various cardiovascular diseases, including chronic ischemia, by regulating VEGF signaling and modulating angiogenesis; it is a potent inhibitor of LPS-stimulated VSMC inflammatory responses through blockade of NF-kappaB activity and inhibition of inflammatory gene COX-2 expression. 1-O-Acetylbritannilactone may act as potent natural skin-lightening agents, it exhibits anti-melanogenic activity by suppression of tyrosinase expression via ERK and Akt signaling.

Rebaudioside M is a rebaudioside that is rebaudioside A in which the the hydroxy groups at positions 2 and 3 of the beta-D-glucosyl ester moiety have both been converted to the corresponding beta-D-glucoside. Found in very low concentraitions in the leaves of Stevia Rebaudiana, it is more than 200 times sweeter than sucrose. It has a role as a sweetening agent. It is a rebaudioside and a beta-D-glucoside.

Epitheaflagallin 3-O-gallate is a promising functional food material with potential antiobesity and antiperiodontal disease activities, it suppresses tumor growth through the suppression of angiogenesis. Epitheaflagallin 3-O-gallate also shows antioxidative activity, pancreatic lipase inhibition, Streptococcus sorbinus glycosyltransferase inhibition, and an inhibiting effect on the activity of matrix metalloprotease-1 and -3.

Cinnamtannin B-1 is a proanthocyanidin found in Cinnamomum cassia and Cinnamomum zeylanicum. It has a role as a cyclooxygenase 2 inhibitor and a plant metabolite.

Rebaudioside B is a rebaudioside that is steviol in which the hydroxy group is replaced by a beta-D-glucopyranosyl-(12)-[beta-D-glucopyranosyl-(13)]-beta-D-glucopyranosyl group. It has a role as a sweetening agent. It is a rebaudioside, a beta-D-glucoside and a trisaccharide derivative. It is functionally related to a beta-D-Glcp-(1->2)-[beta-D-Glcp-(1->3)]-beta-D-Glcp. It is a conjugate acid of a rebaudioside B(1-). Rebaudioside B tastes about 150 times sweeter than sucrose and it is non-caloric.

Violanthin is a flavone C-glycoside that is flavone substituted by hydroxy groups at positions 5, 7 and 4', a beta-D-glucopyranosyl residue at position 6 and a 6-deoxy-alpha-L-mannopyranosyl residue at position 8. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor and a plant metabolite. It is a trihydroxyflavone and a flavone C-glycoside. It is functionally related to a flavone.
