Problems solved by technology

At present, when hollyhock flowers are used as the main raw material for deep processing, preparation processes such as ethanol reflux extraction and concentration are often used. During this process, the ethanol extract is easy to precipitate a large amount of precipitate and suspended matter after cooling and concentration. At present, most of the production processes only use its extract. or concentrated liquid, and the precipitated and suspended solids are discarded as waste, resulting in waste of resources and environmental pollution

Abstract

The invention discloses flower wax, honey and flavone part extracted from a byproduct in the abelmoschus manihot pharmaceutical manufacturing process, as well as a preparation method and application thereof. According to the preparation method, in the abelmoschus manihot preparation producing process, precipitate and suspension which are separated after the extracting liquid obtained by hot ethanol extraction is coolec are used as raw materials, and are extracted with a low-polarity organic solvent; the solvent is reclaimed from the extracting liquid, and saponified to prepare flower wax; the remained residue is separated with polyamide column chromatography to respectively prepare honey and flavone part to respectively prepare functional cosmetic matrix, health-care soap base, livestock and poultry health feed and anti-oxidation functional products. By adopting the method, the byproduct generated in the abelmoschus manihot preparation producing process is used as the raw material and separated to prepare available substances, so that waste is turned into valuables, and resource utilization can be achieved. The preparation method is low in raw material cost, can provide an approach to harmless effective disposal of waste, and lays a foundation for sustained development and industrial chain recycling of abelmoschus manihot medicinal resource industry.

Description

technical field [0001] The present invention relates to a method for recycling by-products in the production process of traditional Chinese medicine, in particular to a method for preparing flower wax, honey, and flavonoid parts through a continuous complete process by using the by-products in the production process of marshmallow flower preparations as raw materials and its application. Background technique [0002] Hollyhock (Abelmoschus manihot (L.) Medic.) is a one-year to perennial herb of the Malvaceae genus Abelmoschus. It was first recorded in "Jiayou Materia Medica" written by Zhang Yuxi in the Song Dynasty. There are many records. Altha marshmallow is currently one of the main raw materials of traditional Chinese medicine preparations commonly used in the treatment of kidney disease, with a huge industrial scale. At present, when hollyhock flowers are used as the main raw material for deep processing, preparation processes such as ethanol reflux extraction and co...
