rheum

Methods: Radix Rheum, Leech, Fructus Arctium in Huangzhi Oral Liquids was identified by TLC.(方法：采用薄层色谱法鉴别黄蛭口服液中的大黄、水蛭、牛蒡子。)

The cultivated Rheum required quantity has an increase for the Fe, Mn, Co, and decrease for the Zn, cu, Ni element nutrition with the growth age changes.(随着生长年龄增加种植大黄对铁、锰、钴元素营养需求量有所增加，对锌、铜、镍元素营养的需求量略减。)

Using the information of the general survey of Chinese drugs in 1986-1992 as a basis, author reports the growing environments, distributions and reserves of 15 species of Rheum in Qinghai Province.(本文以1986～1992年青海省中药普查资料为依据，报道青海省大黄属15个种的生境、分布及蕴藏量，供开发利用参考。)

These can help people to recognize the constituents of Polygonum Cuspidatum, Rheum and Semen Cassiae and also apply to science research of the new Antineoplastic Constituents.(本课题不仅丰富了对天然蒽醌中虎杖、大黄、决明子化学成分及其抗癌活性的了解，而且为进一步研究开发新的抗肿瘤活性物质提供了科学依据。)

Results After the analysis of multiple factors, the dangerous factors were puisne, often rheum, chronic respiratory disease history, bad healthy and so on.(结果多因素分析显示，低年龄段、经常感冒，有慢性呼吸系统疾病史和个人健康状况差，是个人好发急性呼吸道感染的危险因素。)

The rhubarb plant (Rheum palaestinum), however, takes an entirely different approach: its huge leaves funnel water to its single root.(该大黄类植物(Rheumpalaestinum)却采取了完全不同的另外一种方式：巨大的叶子将水分引导到独根里面。)

He turned towards me, and looked into my eyes with two filmy orbs that distilled the rheum of intoxication.(他朝我转过身，用两只因醉酒像要渗出黏液的朦胧的眼睛看着我。)

The differences of 7 kinds of Rheum were compared by HPLC-FPS in this study. The column figures and the retrieval table were drawn.(本实验采用高效液相色谱——指纹图谱法分析并比较了7种大黄的化学成分间的差异，绘制了条形图和检索表。)

The research aimed to master the distribution characteristics of anthraquinone compounds in the stem of Rheum tanguticum Maxim. et Balf.(目的］为了系统掌握六盘山鸡爪大黄茎蒽醌类化合物的分布特征。)

Methods:The extracting conditions and adsorptive characteristics and elutive parameters of the process were studied by taking the extraction efficiency and purified ratio of Rheum as mark.(方法以大黄总蒽醌的提取率及洗脱率为考察指标，考察大黄的提取条件及大孔吸附树脂富集、纯化大黄总蒽醌的吸附性能和洗脱参数。)
