Polygonum Cuspidatum Extract Oil Introduction

In traditional Chinese medicine in the first century BC, clinical outcomes supported by clinical outcomes include acute microbial infection or viral hepatitis, chemical or radioactive leukopenia, atherosclerosis and hyperlipidemia. China is the main origin of the knotweed. The raw materials are wild natural sources.

Resveratrol can be produced from polydatin fermented by Aspergillus oryzae. That’s why people call polydatin as the precursor of resveratrol. This latter species produces a piceid-b-D-glucosidase.Trans-piceid is the glucoside formed with trans-resveratrol, while cis-piceid is formed with cis-resveratrol. Trans-resveratrol-3-O-glucuronide is one of the two metabolites of trans-piceid in rat. 

It has the functions of protecting cardiovascular, protecting liver and gallbladder, and fighting cancer. Polygonum cuspidatum extract has been widely used in many industries such as medicine, health care products, cosmetics, etc., and the international market has a large demand space.
