A high-performance liquid chromatographic (HPLC) method with ultraviolet absorption detection was developed to determine the presence of anthraquinones, polydatin, and resveratrol in Polygonum multiflorum Thunb. as well as other medicinal Polygonum species, viz., P. cuspidatum, P. oriental, P.
A new biotransformation method of producing resveratrol with co-immobilized edible Aspergillus niger and Yeast (AY) was investigated. The biotransformation conditions were optimized for the resveratrol production under 30 °C, pH 6.5, 2 days, liquid-solid ratio 12:1 (mL/g), the yield of resveratrol
OBJECTIVE
To optimize the ultrahigh pressure extraction (UPE) process of polydatin and resveratrol from Polygonum cuspidatum by using uniform design.
METHODS
On the basis of single factor screening, the uniform design was adopted for getting the optimal technique parameters. The optimum result of
OBJECTIVE
To compare the contents of resveratrol and polydatin in some materials of Polygonum cuspidatum from various sources, so to screen and obtain the suitable cultures for the following metabolism regulation study.
METHODS
RP-HPLC method was applied to simultaneously assay resveratrol and
Resveratrol, a bioactive compound in high quantities in Polygonum cuspidatum, has well-known health benefits. However, it mainly exists in its glycosidic form, polydatin, in plants. To increase the production of resveratrol for various uses in medicine, foods, and cosmetics, an efficient
Hyperlipidaemias are common in obese people, and they increase the risk of cardiovascular diseases such as coronary heart disease (CHD) and atherosclerosis (AS). Previous studies have shown that several drugs can depress serum cholesterol. However, they could cause serious side effects in various
Hyperlipidemia is one of the vital coronary risk factors and is positively related to morbidity and mortality of coronary heart disease. There are numerous herbal medicines which are reported to exert good hypolipidemic actions with few side effects. In the present study, the hypolipidemic effects
Background:Polygonum cuspidatum Siebold & Zucc. (PCS) has antibacterial properties and may prevent Ulcerative colitis (UC) but related molecular mechanism remains unknown. NF-κB signaling pathway is associated with inflammatory responses and its inactivation may be critical for effective therapy of
Polydatin is one of main compounds in Polygonum cuspidatum, a plant with both medicinal and nutritional value. The possible hepatoprotective effects of polydatin on acute liver injury mice induced by carbon tetrachloride (CCl(4)) and the mechanisms involved were investigated. Intraperitoneal
A hyphenated strategy by off-line coupling 1, 1'-diphenyl-2-picrylhydrazyl -HPLC, high-speed counter-current chromatography and preparative HPLC was established to screen and separate antioxidants from ethyl acetate fraction of the roots of Polygonum multiflorum. Under the target-guidance of 1,
OBJECTIVE
To study the technological parameters of the purification process for effective part from Polygonum cuspidatum.
METHODS
Using adsorption capacities and desorption rates of polydatin, resveratrol,emodin,physcion and total anthraquinone as the primary screening indexes, six resins were
Background: Polygonum cuspidatum Sieb. et Zucc. (named Huzhang in China) is a traditional and popular Chinese medicinal herb used in removing jaundice, clearing heat-toxin, improving blood circulation, expelling stasis, dispelling wind and dampness, repelling phlegm, and suppressing cough. It is
Resveratrol, a polyphenol compound with strong biological activity, has been widely used in medicine, health products and cosmetic industries. It is also the main active component of Polygonum cuspidatum, a well-known traditional Chinese medicine. We developed a simple and effective method for the
Polygonum cuspidatum root has been traditionally used for the treatment of dental diseases in Korea. The purpose of this study was to evaluate effects of P. cuspidatum root on the development of dental caries, especially its effects against bacterial viability and caries-inducing factors of
Methylglyoxal (MGO), a very reactive metabolite of glucose, plays a pivotal role in the pathogenesis of several chronic diseases associated with diabetes, and it has been validated as an attractive target for them. In the present study, a simple and effective method, namely pre-column incubation
