Abstract

The invention relates to the field of medicine component detection, and provides a TLC identification method of radix stemonae in compound siraitia grosvenorii cough-relieving granules, which comprises the following steps: comparing a thin-layer chromatogram of the compound siraitia grosvenorii cough-relieving granules, a thin-layer chromatogram of a radix stemonae reference medicinal material and a thin-layer chromatogram of a negative reference medicinal material without the radix stemonae, so that the radix stemonae medicinal material in the compound siraitia grosvenorii cough-relieving granules can be quickly and effectively identified.

Description

technical field [0001] The invention relates to the field of detection of pharmaceutical components, in particular to a TLC identification method for the components of compound Luo Han Guo Zhi Ke granules. Background technique [0002] Baibu, also known as mother-in-law grass, medicine for lice, is a plant of the family Libuceae. Baibu is a perennial herb, with spindle-shaped fleshy roots clustered underground, the upper part of the stem climbs up to other things, ovate leaves, 2-4 whorled nodes, light green flowers bloom in early spring, and the pedicel is attached to the main vein of the leaf, like a flower It grows from the leaves and grows at an altitude of 300 to 400 meters. The roots can be used as medicine and are toxic; external use can repel mosquitoes, and internal use has the functions of eliminating phlegm and relieving cough, and has high medicinal value. [0003] In the latest version of the Chinese Pharmacopoeia (2015 edition, part one), under the item of hun...
