Abstract

The invention discloses an establishment method of a fingerprint spectrum of a fragrant plantain lily flower in mongolian medicine, and a standard fingerprint spectrum of the fragrant plantain lily flower in the mongolian medicine. The method comprises the following steps: precisely weighing 0.5g of fragrant plantain lily flower medicinal material powder; arranging the medicinal material powder in a 100mL conical flask with a cover; precisely adding 60mL of 60% ethyl alcohol; performing supersonic extraction for 45min; filtering to obtain filter residue; cleaning the filter residue three times with the 60% ethyl alcohol, wherein 10mL of the ethyl alcohol is consumed each time; performing decompression recycling on solvents until the solvents are dry; making to constant volume of the dry recovered solvents into a 25mL measuring flask by using 10% methyl alcohol; diluting to the scale; shaking up uniformly; filtering by a micro-pore filter film to obtain subsequent filtrate for later use; and performing chromatographic step, wherein the chromatographic conditions are as follows: a chromatographic column is Alltima5muC18, a flowing phase is methyl alcohol-water, the elution gradient is 5%B0min-10%B25min-27%B58min-40%B61min70%B80min-100%B90min, the detection wave length is 265nm; the column temperature is 30 DEG C, the flowing speed is 1mL / min, and the sampling size is 20muL. A high performance liquid chromatography is adopted for performing fingerprint spectrum researches on the fragrant plantain lily flower in the mongolian medicine, and the establishment method is used for evaluating the validity, the excellent performance and the stability of the quality of the fragrant plantain lily flower medicinal material.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a method for establishing a fingerprint of Mongolian medicine hosta flower and a standard fingerprint thereof. Background technique [0002] In recent years, the international botanical drug market demand has been increasing, and our country's botanical drug resources are facing a serious shortage of medicinal raw materials. Due to the influence of a series of processes such as the base source, the environment and climate of the place of origin, the harvest time, and the processing method, the ingredients contained in the raw materials of Chinese and Mongolian medicines often vary greatly, and the authenticity, uniformity, and stability of the quality are difficult to guarantee. At the same time, under the lure of huge profits, many drug companies disregarded the safety of consumers and passed off fakes as real ones. The quality problem of Chinese and Mongolian medicine has become a t...
