Content determination method for multiple components in Yupingfeng preparation

The invention relates to a content determination method for multiple components in a Yupingfeng preparation. The method comprises the steps of: (1) taking the Yupingfeng preparation, crushing or not crushing it, then performing precise weighing, adding methanol to conduct reflux extraction for 1-3h, carrying out filtration and concentration, then adding methanol to a constant volume, thus obtaining a test solution; (2) precisely weighing the reference substance prim-o-glucosylcimifugin, calycosin-7-glucoside, cimifugin, 5-O-methylvisammioside, sec-o-glucosylhamaudol, calycosin, formononetin, atractylenolide III, atractylenolide I and atractylenolide II respectively, and adding methanol to perform dissolving to a constant volume, thus obtaining a mixed reference solution; (3) conducting determination: precisely sucking the test solution and the mixed reference solution respectively, injecting them into a high performance liquid chromatograph, carrying out gradient elution under certain mobile phase condition, and performing multi-wavelength simultaneous monitoring, thus obtaining the content. The method provided by the invention can accurately determine the content of 10 components in the Yupingeng preparation, and can objectively, comprehensively and sensitively reflect the quality condition of the Yupingfeng preparation.

Construction method for HPLC specific chromatogram of fine astragalus mongholicus ginseng and salviae miltiorrhizae capsules

The invention relates to the technical field of medicines, in particular to a construction method for an HPLC specific chromatogram of fine astragalus mongholicus ginseng and salviae miltiorrhizae capsules. The construction method comprises the following steps: taking the content of the fine astragalus mongholicus ginseng and salviae miltiorrhizae capsules, adding methanol, filtering the mixture after ultrasonic treatment, and taking a continuous filtrate to obtain a solution of a sample for test; taking a ginsenoside Rg1 reference substance, a danshinolic acid B reference substance, a formononetin reference substance and a tanshinone IIA reference substance to be mixed, and adding methanol to obtain a reference substance solution; testing the solution of the sample for test and the reference substance solution by means of high performance liquid chromatography separately to obtain the HPLC specific chromatogram of the fine astragalus mongholicus ginseng and salviae miltiorrhizae capsules, wherein the chromatographic condition of the high performance liquid chromatography is as follows: by taking a C18 column as a chromatographic column, acetonitrile as a moving phase A and a 0.1%phosphoric acid solution as a moving phase B, gradient elution is carried out. The specific chromatogram of fine astragalus mongholicus ginseng and salviae miltiorrhizae capsules established by the method is relatively good in separating degree, and meanwhile, 15 active components of traditional Chinese medicines can be separated and detected at the same time.

Method for evaluating honeysuckle characteristics based on marker flavonoids screened by metabolome

ActiveCN111337586AEfficient and high-throughput detection methodGood repeatabilityComponent separationBiotechnologyBiochemistry
The invention relates to a method for evaluating honeysuckle characteristics based on marker flavonoids screened by metabolome. According to the invention, the method comprises the steps: employing the flavonoid components and the content of the flavonoid components of flower buds/flowers of honeysuckle in different development stages by virtue of an LC-MS/MS technology; quantitatively analyzing the flavonoid difference in different development stages and screening the labeled flavonoid substances in each development stage of the medicinal bud stage, so as to judge the flavonoid category and content of the fresh honeysuckle raw material. The screened formononetin and 7-oxomethyl quercetin can be used as specific marker flavonoid substances in the optimal medicinal bud stage (the second white stage); the 2, 6-gingerol can be used as a specific marker flavonoid substance in the three-green stage, and the peach aglycone can be used as a specific marker flavonoid substance in the large white stage. The invention also provides a basis for extraction and quantitative detection of honeysuckle flavonoids of different cultivated varieties in different cultivation regions, and provides an evaluation method for judging the flavonoid substance characteristics of fresh honeysuckle samples.
