UV was applied to determine the concentration of total alkaloids and total flavones; Simultaneous determination of berberine, jatrorrhizine, palmatine, baicalin and geniposide by HPLC; The solid holdup and precipitation rate were calculated by the formula.

采用UV测定其中总生物碱、总黄酮的量， HPLC同时测定小檗碱、药根碱、巴马汀、黄芩苷、栀子苷的量；计算固含率，沉淀率。

In conclusion, Macleaya cordata extracts improved growth performance and alleviated weaning stress in weanling piglets. This study demonstrates the potential use of Macleaya cordata extracts as a feed additive of weaned piglets instead of antibiotics.

试验显示，血根碱和博落回提取物均能显著提高断奶仔猪的生长性能，有效缓解了断奶应激，血根碱或博落回提取物作为植物源性抗生素替代抗产品在断奶仔猪日粮中有良好的应用效果。

The research results will conduce to the exploration of Mahonia plants.3^ In the experiment, we induced callus with the M.eurybracteata.

用HPLC法对收集到的材料茎中三种主要生物碱(小檗碱、药根碱、巴马汀)的含量进行了分析。

Objective: To study the effects of Total Alkaloid of Menispermum on apoptosis, cell cycle and invasive ablity to the Hela cell. To investigate the antitumor mechanisms of TAM.

目的：研究北豆根总碱对宫颈癌细胞Hela凋亡、细胞周期及侵袭性的影响，探讨北豆根总碱抗肿瘤作用机制，为抗肿瘤新药的研究和开发提供科学依据。

In alkali metasomatic rocks, potassium is in reverse correlation with gold; and sodium is in reverse correlation with uranium, it is very important to ore-formation of uranium and gold.

研究中还认识到，在碱交代作用形成的碱交代岩中，钾与金负相关，钠与铀负相关，这对铀、金成矿有着重要的意义。
