Plastid trnL-trnF and nuclear ribosomal ITS sequences were obtained from selected wild-type individuals of Polygonum minus Huds. in Peninsular Malaysia. The 380 bp trnL-trnF sequences of the Polygonum minus accessions were identical. Therefore, the trnL-trnF failed to distinguish between the Polygonum minus accessions. However, the divergence of ITS sequences (650 bp) among the Polygonum minus ...

The genus Polygonum encompasses approximately 300 species widely distributed around the world, among which 120 Polygonum species grow in China. Among the rich species, 81 of them are widely used in traditional Chinese and folk medicines. In recent years, several studies have found that the genus Polygonum posseses a variety of biological activities including antioxidation, antimicrobial, antitu...

to extract active components from the traditional Chinese medicine Polygonum cuspidatum using a trans-resveratrol imprinted polymer. Good separation and purification of trans-resveratrol and emodin from the Polygonum cuspidatum extract are achieved after condition optimization. The extraction recoveries are 83% and 99% for trans-resveratol and emodin, respectively. The results show that the mol...

Pharmacognostic studies on leaf of Polygonum glabrum Willd. has been carried out along with its numerical values, fluorescence characteristics and ash and extractive values.

The protective effects of two Chinese herbs, astragalus mongholicus, polygonum multiflorum and astragalus mongholicus-polygonum multiflorum in combination against thymus injury induced by cyclophosphamide were evaluated by transmission electron microscopy, image analysis, DNA gel electrophoresis as well as flow cytometry. Results showed that mice pretreated with cyclophosphamide had degenerated...

BACKGROUND AND THE PURPOSE OF THE STUDY One of the most common malignancies in women is breast cancer. Although several treatments for breast cancer are available, application of herbal medicine as a supplementary treatment is a new option to help curing the disease. In this study anticancer effects of Polygonum avicular herbal extract was investigated. METHODS Polygonum avicular extract was ...

HPTLC analysis was carried out to determine the steroid compounds profile in the whole-plant samples of selected Polygonum species (P. chinense, P. glabrum and P. barbatum). The methanol extract of whole-plant samples obtained from Polygonum species (P. chinense, P. glabrum and P. barbatum) showed 6, 6 and 5 compounds, respectively, and were compared with stigmasterol and solasodine standards. ...

For more than a century, the common ancestor of flowering plants was thought to have had a seven-celled, eight-nucleate Polygonum-type female gametophyte. It is now evident that not one, but in fact three, patterns of female gametophyte development and mature structure characterize the common ancestors of the four most ancient clades of extant angiosperms: Amborella-type, Nuphar/Schisandra-type...

Numerous diseases are induced by free radicals via lipid peroxidation, protein peroxidation and DNA damage. It has been known that a variety of plant extracts have antioxidant activities to scavenge free radicals. Whether Polygonum cuspidatum Sieb. et Zuce has antioxidant activity is unknown. In this study, dried roots of Polygonum cuspidatum were extracted by ethanol and the extract was lyophi...

BACKGROUND Polygonum minus is an herbal plant in the Polygonaceae family which is rich in ethnomedicinal plants. The chemical composition and characteristic pungent fragrance of Polygonum minus have been extensively studied due to its culinary and medicinal properties. There are only a few transcriptome sequences available for species from this important family of medicinal plants. The limited ...
