Latest Patents

Lian’s listed patents cover cannabidiol extraction and the simultaneous preparation of chlorogenic acid and stevioside.

“Industrial extraction method of cannabidiol” describes a process involving raw-material pretreatment, granulation, extraction, liquid-liquid extraction, decolorization, and concentration. The method is designed to improve wax removal and extraction yield while reducing tetrahydrocannabinol content. According to the disclosure, it can produce crude cannabidiol oil with purity of up to 60%, remove 40% of tetrahydrocannabinol, and support large-scale industrial production at relatively low cost.

“Industrial method for simultaneously preparing chlorogenic acid and stevioside” describes alcohol extraction followed by adjustment of the feed liquid and separation using a water-insoluble, moderately polar organic solvent. The process enriches chlorogenic acid in the organic layer and stevioside in the water layer. The patent presents potential benefits including reduced hydrolysis of chlorogenic acid, preservation of product quality, improved production efficiency, and lower water consumption and wastewater discharge.
