Methods and applications for increasing the content of active ingredients, consistency of chemical composition and/or therapeutic benefits of plants of the genus Larnia

Abstract

A method and application for increasing the content of active ingredients, the consistency of the chemical composition of medicinal materials, and / or the therapeutic effect of plants of the genus Larnia, which includes, before performing optional extraction treatment on the harvested plants of the genus Larnia, Carrying out a drying process on the Larnia plant first, so as to increase the active ingredient content, the consistency of the chemical composition of the medicinal material and / or the therapeutic effect of the Larnia plant or its extract, wherein the drying process is carried out in at a temperature of 35 to 45°C.

Description

technical field [0001] The present invention relates to the processing improvement of Larnia plants, wherein the harvested Larnia plants are subjected to a temperature of 35° C. to 45° C. The plant is subjected to a drying process, thereby increasing the content of active ingredients, the consistency of the chemical composition of the medicinal material, and / or the therapeutic benefit of the Larnia genus or its extract. The present invention also relates to the Larnia plant or its extract obtained by the aforementioned processing improvement method. Background technique [0002] Lararia crinita (L.) Desv.ex DC.), Uraria lagopodioides (L.) Desv.ex DC.), Uraria picta (Jacq.) Desv. ex DC.), Uraria neglecta Prain and other Uraria neglecta Prain plants (Uraria spp.) are commonly used to invigorate the spleen and stomach, relieve cough and moisten the throat, remove malnutrition, treat diarrhea, and treat children with dysplasia. , detoxification, swelling and Chinese medicinal ...

AI Technical Summary

Problems solved by technology

When Chinese herbal medicines are harvested, the water content is high. If they are not processed in time, they are easy to rot and deteriorate, which seriously affects the quality, clinical efficacy and economic benefits of medicinal herbs.

[0005] Taking the drying processing of medicinal materials as an example, the traditional drying methods relying on sun drying or shade drying are inefficient, and there is a large deviation between shade drying and sun drying due to reasons such as not drying in time or inconsistent drying conditions, thus affecting the quality of medicinal materials

[0006] In order to prevent mildew and corruption of medicinal materials, some farmers use sulfur fumigation for processing, which may easily cause excessive sulfur dioxide residues and endanger human health.

[0007] At present, after harvesting, Larnia plants are directly processed by farmers at the place of origin. Due to the lack of good processing and processing standards, farmers in various places adopt different processing methods and conditions after harvesting, which leads to heterogeneity. The production (heterogeneousness) seriously affects the biological activity and content of active ingredients in medicinal materials, resulting in unstable quality of medicinal materials in Salvia genus, which is not conducive to the treatment and control of related diseases. For example, see: Production of salvianolic acid B in roots of Salvia miltiorrhiza (Danshen) during the post-harvest drying process.Molecules,2012. 17(3):p.2388-407
