Problems solved by technology

[0003] But at present, there is no quality standard for the medicinal materials of shikanzi, and the quality control of the medicinal materials of shikanzi is very weak. It only includes routine inspections such as microscopic identification, lacks a perfect quality evaluation system, and it is difficult to achieve effective control of the quality of shikanzi.

Abstract

The present invention discloses a construction method of Pothos chinensis HPLC fingerprint of and an HPLC fingerprint based on high-performance liquid chromatography. The fingerprint has 16 common peaks with the following relative retention time tg: 0.178min, 0.268min, 0.309min, 0.354min, 0.411min, 0.488min, 0.507min, 0.633min, 0.730min, 0.922min, 1.000min, 1.318min, 1.326min, 1.525min, 1.544min, and 1.579min. Through the presence or absence of common peaks in the fingerprint, a comprehensive quality evaluation of Pothos chinensis can be carried out, so as to ensure the stability of medicinal quality and effectiveness and safety of clinical medication.

Description

technical field [0001] The invention relates to the technical field of quality detection of traditional Chinese medicines, in particular to a method for constructing an HPLC fingerprint of ponzu and its HPLC fingerprint. Background technique [0002] Mandarin is the dried whole herb of Pothoschinensis (Raf.) Merr., a plant of the genus Pothoschinensis (Raf.) Merr. in the family Araceae. Lime mandarin is flat in nature and light in taste. It has the effects of dispelling wind and dampness, promoting blood circulation and dispersing blood stasis, eliminating stagnation and relieving cough. It is often used in the Yao area to treat bruises and rheumatic bone pain. The curative effect is remarkable. Due to the complex composition of traditional Chinese medicine, it is difficult to accurately evaluate the quality of traditional Chinese medicine only by a single index. Traditional Chinese medicine fingerprint refers to the chromatogram or spectral spectrum of a certain type or se...
