Title: Yanfang Wang and an Industrial Method for Preparing Chlorogenic Acid and Stevioside.

Introduction

Yanfang Wang is an inventor associated with Hebei, China, and Chenguang Biotech Group Co., Ltd. Her patent work includes a method designed to prepare chlorogenic acid and stevioside simultaneously.

Latest Patents

Wang is credited with 1 patent: “Industrial Method for Simultaneously Preparing Chlorogenic Acid and Stevioside.” The invention describes alcohol extraction followed by adjustment of the feed liquid so chlorogenic acid enters a free molecular state. A water-insoluble, moderately polar organic solvent is then used to separate the compounds, enriching chlorogenic acid in the organic layer and stevioside in the water layer.

The patent presents the process as an alternative to traditional water extraction. It aims to limit hydrolysis of chlorogenic acid, preserve the composition of the resulting product, and separate the compounds without compromising stevioside quality or production efficiency. The method also seeks to reduce water consumption, sewage discharge, and flocculation residues.

Career Highlights

Wang’s listed invention focuses on improving the efficiency and environmental profile of botanical ingredient production. Its stated objectives include maintaining a chlorogenic-acid profile closer to that of the raw material and supporting the production of both chlorogenic acid and stevioside.

Collaborations

Wang’s listed coworkers include Yunhe Lian and Meili Xu. Her company affiliation is Chenguang Biotech Group Co., Ltd.

Conclusion

Yanfang Wang’s patent describes a combined extraction and separation process intended to produce chlorogenic acid and stevioside while reducing resource use and production waste.
