Study on Extraction Technique for Blood Lipid Lowering Effective Components in Rhizoma Alismatis / 中国药房

OBJECTIVE: To screen the optimal extraction technique for the blood-lipid lowering effective components in rhizoma alismatis.METHODS: In an orthogonal test, the influence of 4 factors: alcohol concentration, extraction time, extraction frequency, and alcohol dosage, on the extraction was investigated by using the value of ultraviolet absorption of total triterpenes sapogenins in rhizoma alismatis as the investigated index.RESULTS: The optimal extraction technique for blood-lipid lowering effective components in rhizoma alismatis was to extract the medicinal material in 90% alcohol 5 times the amount of the material for 2 times with 2 hours for each time.CONCLUSION: The extraction technique is reasonable and practicable.
