Cinnamic acid, a naturally occurring aromatic fatty acid of low toxicity, has anti-diabetic , anticancer and antioxidant activities. It is a cell differentiation inducer and protein isoprenylation inhibitor, shows a significant radio-protective effect by reducing the DNA damage induced by X-rays. Cinnamic acid inhibited feeding by detritivores, this inhibition occurs at concentrations found in nature and may be a major factor controlling the rate of decay of organic matter. It inhibited mushroom tyrosinase activity in reversiblywith the IC 50 value of 2.10 mM. Cinnamic acid is a monocarboxylic acid that consists of acrylic acid bearing a phenyl substituent at the 3-position. It is found in Cinnamomum cassia. It has a role as a plant metabolite. It is a member of cinnamic acids and a member of styrenes. It is a conjugate acid of a cinnamate.

Hellebrigenol shows cytotoxicity against HepG2 cells.

Asiaticoside, a biochemical modulator, which has antioxidant, anti-inflammatory, antipyretic, anxiolytic-like, anti-gastric ulcers, hepatoprotective, and antidepressant-like effects, it also exhibits significant wound healing activity in normal as well as delayed healing models. Asiaticoside suppressed collagen expression and TGF-β/Smad signaling through inducing Smad7 and inhibiting TGF-βRI and TGF-βRII in keloid fibroblasts. It and its derivatives can be regarded as reasonable candidates for a therapeutic Alzheimer's disease drug that protects neurons from Abeta toxicity. Asiaticoside is a triterpenoid saponin that is a trisaccharide derivative of asiatic acid. Isolated from Centella asiatica, it exhibits anti-inflammatory, antioxidant and wound-healing properties. It has a role as an antioxidant, an antifibrotic agent, an antidepressant, an antineoplastic agent, a neuroprotective agent, an anti-inflammatory agent, a vulnerary and a plant metabolite. It is a pentacyclic triterpenoid, a carboxylic ester, a triterpenoid saponin and a trisaccharide derivative.
