ABSTRACT
Objective To study the quality standard of the imitation ecological planting Anoectochilus roxburghii under forest covering. Methods The identification of medicinal properties, microscopic characteristics, thin-layer chromatography (TLC) and content determination of A. roxburghii cultivated under forest were carried out in this study, and the moisture content, ash and acid-insoluble ash were determined according to Chinese Pharmacopoeia of 2015 edition. Results A. roxburghii cultivated under forest exhibits specific properties in characteristics, microscopic features and TLC results. The average moisture content of A. roxburghii cultivated under forest from five planting bases was 8.69%, the average ash was 11.93%, and the average acid-insoluble ash was 3.27%. Content determination results of the average quality score of quercetin, isorhamnetin and kaempferide were at 0.021 0%,,0.024 7%, and 0.027 3%, respectively. Conclusion The above method is simple, specific and reproducible, which will provide the basis for the quality standard of the imitation ecological planting A. roxburghii under forest covering.
ABSTRACT
Objective:To compare 4 polyphyllins contents in Paris polyphylla planted under walnut forest in different areas of Yun-nan Yangbi. Methods:Paris polyphylla samples planted under walnut forest were collected in different areas of Yunnan Yangbi, and according to the methods described in Chinese Pharmacopoeia (2015 edition), the contents were determined. Results:Yunnan Yangbi different planted in Paris polyphylla four polyphyllins content of each sample there were significant differences between samples were cultivated in imitation of the wild forest, but the cultivation of varying lengths of time, the growth period of 4 to 5 years in Paris polyphylla four polyphyllins content was significantly higher than that of 3 born in Paris polyphylla. Conclusion: Four kinds of Paris polyphylla saponin content of the samples have significant differences with the Paris polyphylla growth of ecological environment, growth period and the same species living on different populations, the genetic background.
