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)
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)
OBJECTIVE To explore the survey methods for the cultivated medicinal plant resources such as Panax notogingseng based on remote sensing. METHOD Through the preliminary study by remote sensing technique and field survey in the study area, the optimal methods in the procedure were chosen for the survey. RESULT In this study,a set of survey method for P.(More)
In this study, we examined steady-state and dynamic photosynthetic performance and leaf nitrogen (N) partitioning in the typical shade-demanding herb Panax notoginseng grown along a light gradient. Gas exchange on a leaf area basis was significantly reduced under low irradiance, with gas exchange on a leaf mass basis reaching a maximum value and then(More)
Panax notoginseng is a commonly used traditional Chinese medicine with blood activating effect while has continuous cropping obstacle problem in planting process. In present study, a semimicroextraction method with water-saturated n-butanol on 0.1 g notoginseng sample was established with good repeatability (RSD<2.5%) and 9.6%-20.6% higher extraction(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)
DNA marked-assisted selection of medicinal plants accelerated the breeding and promotion of new cultivars, and guaranteed the healthy development of Chinese medicinal materials industry. The first disease-resistant cultivar of notoginseng, namely "Miaoxiang Kangqi 1", served as the object of study. We evaluated the Kangqi's resistance of seeds, seedlings(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)
OBJECTIVE To compare the effects of the different fertilizing levels on the output, the effective element, the content of heavy-metal, the grade and the ratio of wet to dry of Pinella ternate to obtain the best fertilize ratio on the planting. METHODS The orthogonal desing method L9 (3(4)) was applied on the comparison between the different fertilization(More)
