Abstract:
OBJECTIVE: To optimize the extraction technology of pueraria, ophiopogonis, and loquat leaf. METHODS: Orthogonal test was carried out. The influence of concentration of solvent, the dosage of solvent, time length of extraction, and frequency of extraction on extraction results were investigated by using the content of pueraria as index. RESULTS: The optimal extraction technique was to extract pueraria in 60% alcohol 8 times the weight of herbal medicine for 3 times, with 60 minute for each time. CONCLUSION: High yield of extractum and high content of pueraria are obtained with the present technology. The results are stable and replicable, which can provide reference for preparation of Huanglian powder.
