山茱萸良种主要药用有效成分测定与质量评价

为明确山莱萸Comus officinalis审定品种主要药用有效成分，依据药用有效成分进一步筛选最符合栽培目标的品种。采集了应用产量指标选育的9个山茱萸品种母株完熟果实，运用高效液相色谱法测定良种的主要有效成分马钱素、熊果酸和齐墩果酸，并依据药用有效成分进行了品种质量比较。结果表明：八月红、琅红、永安、里高、先锋、太平、玉柱红、大金枣和淳86等9个良种马钱素、熊果酸和齐墩果酸质量分数范围分别为5．920～13．260，1．013～4．771，0．149～1．305g·kg^-1，综合3个主要有效成分评价品种质量以琅红和淳86为最佳。得出山茱萸品种药用有效成分具有不一致性，粗步选择出琅红和淳86为最符合栽培目标的品种。图2表1参9

Measurement of main effective medicinal ingredients of elite cultivars of Cornus officinalis and their quality evaluation

Identification of main effective medicinal ingredients in approved cultivars of Comus officinalis may further screen cuhivars in line with cultivation objectives. Fully mature fruits were collected from 9 selectively bred cuhivars of C. officinalis that were screened on the basis of yield indicators and their main effective ingredients, viz. ursolic acid, oleanolic acid, and colchicines, were measured using high performance liquid chromatography （HPLC）, based on which a comparison was conducted among cultivars in terms of effective ingredient content-based quality. Results revealed that such 9 elite cuhivars as ‘August Red＇ , ‘Langhong＇ , ‘Yongan＇, ‘ Ligao＇, ‘Xianfeng＇, ‘ Peace＇ , ‘ Yuzhuhong＇ ,‘Big Goldendate＇, and ‘Chun 86＇ ranged from 5.920 to 13.260 g·kg^-1 in ursolic acid, 1.013 to 4.771 g·kg^-1 in of effective medicinal ingredients. ‘Langhong＇ and ‘Chun 86＇ were the preliminarily selected cultivars in line with cultivation objectives.
