Embodiment 1

[0076] Determination method of patchouli medicinal material content:

[0077] A. Preparation of the mixed reference substance solution: Weigh an appropriate amount of verbascoside, isoverbacoside, patchouli flavonol, patchouli ketone, New Zealand vitexin 2 and ritangin reference substance, weigh them precisely, and add methanol to make them respectively Each 1mL solution contains 170 μg of verbascoside, 40 μg of isobracoside, 40 μg of New Zealand vitexin 2 and ritangin, and 20 μg of each of Huoxiang flavonol and patchouli ketone, mix well, and obtain;

[0078] B. Preparation of the test solution: crush the patchouli medicinal material, pass it through a No. 4 sieve, take 0.5 g of the medicinal material powder, accurately weigh it, place it in a 50 mL conical flask with a stopper, add 25 mL of 50% methanol, and seal Stopper, weighed, sonicated for 10 minutes, taken out, allowed to cool, weighed again, supplemented the lost weight with 50% methanol, shaken well, took the superna...

Abstract

The invention belongs to the field of traditional Chinese medicine, and particularly relates to a method for simultaneously measuring the contents of six chemical components in herba pogostemonis. Inorder to improve the quality control level of medicinal materials of herba pogostemonis and establish more scientific and reasonable quality standards, a UPLC is adopted for measuring the contents ofthe six components in the medicinal materials of herba pogostemonis for the first time, and a certain experimental basis is provided for improving quality control methods for the medicinal materials of herba pogostemonis and related preparations of herba pogostemonis.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicines, and in particular relates to a method for simultaneously determining the contents of six chemical components in patchouli. Background technique [0002] Patchouli is a labiatae plant patchouli Pogostemon cablin (Blanco) Benth. dry aerial parts. It has the effects of aromatizing turbidity, stopping vomiting, and relieving summer heat. It is used for dampness and turbidity in the middle, nausea and vomiting, heat-dampness syndrome, early onset of dampness and temperature, fever and fatigue, chest tightness and discomfort, cold-damp blocking heat, abdominal pain, vomiting and diarrhea, nasal sinusitis headache. Patchouli is native to Southeast Asia and other countries. my country’s patchouli is mainly introduced from Vietnam, Malaysia and other countries, all of which are cultivated. Now it is mainly distributed in Guangdong, Hainan and other places. It is one of the top ten southern ...
