As a widely used and expensive herbal medicine, Panax ginseng has many adulterants in the commercial market. PCR-restriction fragment length polymorphism (PCR-RFLP) and amplification refractory mutation system (ARMS) based on 5S rDNA sequence analysis were applied to identify two common adulterants of P. ginseng. The sizes of 5S rRNA gene non-transcribed(More)
This review comprehensively summarizes the existing knowledge regarding the chemical implications of anthocyanin glycosyl acylation, the effects of acylation on the stability of acylated anthocyanins and the corresponding mechanisms. Anthocyanin glycosyl acylation commonly refers to the phenomenon in which the hydroxyl groups of anthocyanin glycosyls are(More)
PREMISE OF THE STUDY Microsatellite primers were developed for a Chinese traditional herb, Panax notoginseng, to investigate its genetic diversity and cultivar breeding. METHODS AND RESULTS Twelve polymorphic microsatellite loci were isolated from the microsatellite-enriched genomic library of P. notoginseng. The polymorphisms were assessed in two(More)
In order to discover light quality's effects on growth, photosynthesis and effective components content of Panax notoginseng, a pot experiment using 7 light qualities (red, orange, yellow, green, cyan, violet, and blue) was conducted. The growth, photosynthesis and content change of effective components were measured during plant growth. The results showed(More)
OBJECTIVE The contents of total anthocyanins and total saponins as well as the composition of saponin monomers of Purple and Green Notoginseng Radix et Rhizoma were studied to compare the medicinal quality and commercial values. METHODS Three-year-old Notoginseng Radix et Rhizoma was selected as the research materials. The contents of total anthocyanins(More)
OBJECTIVE To select the main directions and the objects in breeding the high yield of Panax notoginseng by the correlation and path analysis of main agronomic character of P. notoginseng. METHOD Samples in fifty-two districts of Yunnan and Guangxi were collected. The height of plant, the diameter of stem, the number, length, width, size of leaf and the(More)
The cDNA sequence, their structure, physical properties, signal peptide, hydrophobicity, hydrophilicity, subcellular localization domain of transmembrane domain and evolutionary relationship of encoded amino acid sequences were analyzed in squalene synthase of 9 species of ginseng plant using bioinformatics methods on GenBank. The results showed that the(More)
Dear Editor: Colorectal cancer is one of the most common malignant tumors with poor prognosis. New strategies, combined chemotherapies, and antiangiogenesis agents improved the overall survival, but the side effect was also more complicated. Here, we presented a colon cancer patient who underwent subcutaneous tuberculosis during combined therapy of FOLFIRI(More)
OBJECTIVE To study the relationship between the geo-authentic and geologic background system (GBS) and physicochemical properties of soil for the cultivation of Panax notoginseng. METHOD The physicochemical properties of soil were analyzed, the geologic background system between producing areas of Yunnan and Guanxi of P. notogiseng was compared. RESULT(More)
