General description

Astilbin belongs to the class of dihydroflavanol compounds and is the chief biologically active component of Rhizoma Smilacis Glabrae (RSG) extract. RSG is obtained from the dried rhizome of Smilax Glabra Roxb.

Application

Astilbin from Engelhardtia roxburghiana, a flavonoid phytochemical with antibacterial activity, may be used to study its pharmacology and the effects of its antiproliferative activities versus a variety of cell types.

Biochem/physiol Actions

Astilbin exerts various biological activities such as anti-oxidative, anti-bacterial, and inhibition of contact hypersensitivity. Also, it shows insecticidal, anti-oedematogenic, antinociceptive and antidepressant properties. It has an inhibitory effect on the aldose reductase enzyme, the accumulation of sorbitol, and a protective effect on the liver. Astilbin is helpful against autoimmune diseases such as rheumatoid arthritis due to its ability to reduce matrix metalloproteinase (MMP) activity and Nitric oxide production in T lymphocytes.
Flavonoid phytochemical found in St. John′s wort and Traditional Chinese Medicine herbal preparations. Immunosuppresive. Antiproliferative.
