为使中药饮片最大限度的煎出有效成分,提高临床疗效,制定片的厚度标准是保证饮片质量的重要措施之一。虽然《中国药典》和各省市炮制规范对饮片厚度都作了规定,但标准不统一,且多凭经验拟定,而缺乏实验依据。为此,我们以饮片的水溶性物质煎出率为指标,对甘草等十五种药材切制成不同厚度的片,分别进行了煎出率的测定。以供修定饮片标准时参考。一、材料及方法1.样品的制备取规格、质量大致相同的药材,在同一条件下浸润软化,根据药材的性质和机器切制的性能,分别切成1、2、3,2、
In order to make the Chinese Herbal Decoction slice to maximize the effective ingredients and improve the clinical curative effect, it is one of the important measures to ensure the quality of decoction pieces. Although the “Chinese Pharmacopoeia” and the specifications of various provinces and cities have made provisions on the thickness of the decoction pieces, the standards are not uniform, and many are based on experience and lack of experimental evidence. For this purpose, we measured the rate of decocting of fifteen herbs such as licorice by cutting them into slices of different thickness. For reference when setting the standard of decoction pieces. First, materials and methods 1. Preparation of samples Take medicinal materials with the same specifications and quality, infiltrate and soften under the same conditions, according to the properties of herbs and machine cutting performance, cut into 1, 2, 3, 2, respectively.
