Effect of extraction process on extraction yeild, total polyphenol content and antioxidant activity of Jasminum Subtriplinerve

[摘要] Jasminum Subtriplinerve Blume (Oleaceae) is herbal plants widely a tea for weight loss, stimulates milk glands. Extract product it easy used yet had little research. This study was carried out to evaluate the effect of extracting conditions such as water/material ratio, extraction temperature and extracting time on extracting yield, polyphenol content and antioxidant activity of J.subtriplinerve extract. The total phenolic compounds were determined according to the Folin-Ciocalteu method. Extraction yield (0.22g/100 g) was obtained at water/material ratio 15:1 (ml/g), 40C and 4 hours extraction time. Under these optimized conditions, the polyphenol content of was 2640.4 μg/1g extract. And the extract can harvest 46.11 % of DPPH (30 μg/mL) at 10 000 μg/ml concentration
