Abstract:
OBJECTIVE:To optimize the extract technology of the total Favonoids from the fruits of Polygonum viviparum L.METHODS: The content of Flavonoids was computed with rutin as standard substance, and the influence of different factors and levels on the extract technology were investigated by means of simple factor experiment and orthogonal experiment. RESULTS: The optimum extraction technology was as follows: with water-bath temperature at 80℃, the ratio of liquid to solid material at 8∶1 and the concentration of ethanol at 50%, reflux extracting total Favonoids twice(1 h at each time). Under this condition, the content of total Flavonoids was 9.6%. CONCLUSION: The extraction method is appropriate, simple and feasible, and it provided theoretic basis for the production of this product.
