针对目前国内多花黄精种茎无标准和用种不规范的现状,研究多花黄精种茎规格、年龄对产量及药用品质的影响,旨在为多花黄精科学选种用种提供理论依据。采用双因素随机区组设计,主因素为规格,副因素为年龄,以多花黄精种茎的芽头数、茎长、茎径和茎质量为指标,采用K-means聚类法将种茎分成3个规格、3个年龄,通过调查出苗率、单株产量、单位面积产量和块茎多糖含量变化情况,分析不同规格、年龄种茎处理下2年生多花黄精产量和药用品质的差异。种茎规格、年龄与出苗率相关;种茎规格与单株产量、单位面积产量极显著相关,种茎年龄与单株产量、单位面积产量显著相关;种茎规格与多糖含量极显著相关,种茎年龄与多糖含量显著相关。推测种茎规格与年龄存在交互作用,高规格、低龄多花黄精种茎适宜作种,能显著提高多花黄精药材产量和药用品质。

Artemisinin is a potent anti-malarial drug isolated from traditional Chinese medicinal herb, Artemisia annua. The objective of this study was to develop and validate a sensitive and specific LC-MS/MS method for the determination of artemisinin in rat plasma using amlodipine as Internal Standard. The method consist of a simple liquid-liquid extraction with methyl tertiary butyl ether (MTBE) with subsequent evaporation of the supernatant to dryness followed by the analysis of the reconstituted sample by LC-MS/MS with a Z-spray atmospheric pressure ionization (API) interface in the positive ion-multiple reaction monitoring mode to monitor precursor→product ions of m/z 282.70→m/z 209.0 for artemisinin and m/z 408.9→m/z 237.0 for amlodipine respectively. The method was linear (0.999) over the concentration range of 7.8–2000 ng/mL in rat plasma. The intra and inter-day accuracy were measured to be within 94-104.2% and precision (CV) were all less than 5%. The extraction recovery means for internal standard and all the artemisinin concentrations used were between 82-85%.
