AI Technical Summary

Technical Problem

Existing technologies are difficult to efficiently extract high-purity luteolin from chrysanthemums, and the cost is high, especially since column chromatography separation is not very effective.

Method used

A method combining Soxhlet extraction and vacuum concentration with silica gel column separation, including primary and secondary medium-pressure separation, combined with methanol crystallization, was adopted to achieve efficient separation of luteolin by controlling parameters such as the particle size of dried chrysanthemum powder, the ratio of extractant, the particle size of silica gel powder, and the pressure.

Benefits of technology

The extraction of high-purity luteolin glycosides has been achieved, with a purity of over 96%. The raw materials are widely available, low in cost, and suitable for industrial production.
