马钱苷

It is the first time to establish the revered-phase HPLC method to determine concentrations of loganin and morroniside in plasma and to obtain their pharamacokinetic parameters and characteristics.

首次建立了山茱萸注射液中马钱素和莫诺苷血药浓度的HPLC测定方法，阐明了山茱萸中马钱素和莫诺苷的药代动力学参数，方法的专属性强，结果可靠。

ABSTRACT : Objective To identify Angelica., Fructus Schisandrae and Herba Cistanches by TLC method and to determine Loganin in Yubiao Pills by HPLC method.

目的建立鱼鳔丸中当归、五味子、肉苁蓉的薄层鉴别方法及山茱萸中马钱苷的高效液相含量测定方法。

The detection wavelength was 236 nm. RESULTS Loganin had a good linearity (r=0.9998) in the range of 0.093~0.837 μg.

结果 马钱苷0.093~0.837μg与峰面积的线性关系良好(r=0.9998)；回收率为97.7%，RSD=1.4%(n=9)。

Objective: To investigate the absorption mechanism of loganin at different intestine segments of rats and the influence of the drug solution concentration,pH,P-gp inductor.

中文摘要：目的：考察药物浓度、肠段、pH及P-gp对马钱苷肠吸收机制的影响规律。

For content determination, the linear range of loganin was 0.084 μg~0.840 μg, r=0.9999, the average recovery was 98.5%(n=6) and RSD was 1.29%.

HPLC测定的马钱苷在0.084~0.840μg范围内呈良好的线性关系，r=0.9999平均回收率为98.50%，RSD为1.29%。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
