AI Technical Summary
Existing methods for extracting glyceryl oleate from Sanya suffer from problems such as supply shortages, high prices, poor process stability, and low extraction efficiency, making it difficult to achieve large-scale production and widespread application.
Using six ingredients (hemp seed, angelica, notoginseng, chuanxiong, coix seed, and licorice) as raw materials, the extraction process employs two reflux extractions, vacuum concentration, column chromatography separation and purification, and thin-layer chromatography, combined with NMR identification, to clarify process parameters such as the boiling range of petroleum ether, stirring speed, and vacuum degree, ensuring extraction efficiency and purity.
This study achieved efficient and low-cost large-scale preparation of triglycerides of oleic acid, with high product purity and good safety, suitable for cosmetics and pharmaceutical fields, especially for the treatment of atopic dermatitis, reducing product price and broadening application prospects.
