Problems solved by technology

[0003] At present, due to the lack of quality detection methods for the ethyl acetate part of Chuanxiong, the active ingredients in the analgesic effective parts of Chuanxiong obtained from experiments and production are significantly different, resulting in different conclusions about the analgesic effective parts of Chuanxiong in existing research reports. This limits the clinical application of the ethyl acetate part of Chuanxiong, and is also unfavorable for the further development of Chuanxiong.

Abstract

The invention discloses a fingerprint spectrum detection method for an ethyl acetate part of ligusticum wallichii. The fingerprint spectrum detection method adopts high performance liquid chromatography for detection. Through the detection method provided by the invention, the senkyunolide I, the senkyunolide H, the senkyunolide A and the ligustilide in the ligusticum wallichii can be measured atthe same time, the quality of effective parts with the analgesic effect can be controlled, the method is simple, convenient and reliable, a quality evaluation system of the ligusticum wallichii is perfected, the clinical curative effect of the ligusticum wallichii is guaranteed, and practical application and popularization value is achieved.

Description

technical field [0001] The invention relates to the technical field of fingerprints of traditional Chinese medicines, in particular to a method for detecting fingerprints of ethyl acetate parts of Chuanxiong. Background technique [0002] Ligusticum chuanxiong is the dried rhizome of Ligusticum Chuanxiong Hort., an umbrella plant. It is a well-known authentic medicinal material produced in Sichuan. It has the effects of promoting blood circulation and qi, dispelling wind and relieving pain. Irregular menstruation, amenorrhea, dysmenorrhea, abdominal pain, headache, rheumatic arthralgia and other symptoms have been used by physicians of all dynasties as a good medicine for promoting blood circulation and relieving pain. Modern pharmacological studies have shown that Chuanxiong has pharmacological activities such as protecting cardiovascular and cerebrovascular, sedative and analgesic, anticoagulant, and is widely used clinically in the treatment of coronary heart disease, ang...
