| 为研究葡萄皮籽提取白藜芦醇的最优提取条件，采用比色法，在306 nm处测定葡萄皮籽提取物中白藜芦醇的含量，发现白藜芦醇在2.16~10.8 mg/L时，线性关系良好，方法稳定可行；为研究白藜芦醇凝胶剂的最佳制备工艺，选用卡波姆-940为凝胶剂的基质，经单因素和正交试验，筛选白藜芦醇凝胶剂的最佳制备方法，并测定其含量，发现通过优选工艺制备的白藜芦醇凝胶剂外观呈亮白色，均匀细腻，涂展性好。 |

| Abstract: In order to study the optimum extraction conditions of resveratrol extracted from grape skin and seeds, the content of resveratrol in grape skin and seed extract was determined by colorimetric method at 306 nm. It was found that resveratrol had a good linear relationship at 2. 16~10. 8 mg/L, and the method was stable and feasible. In order to study the best preparation process of resveratrol gel, carbomer-940 was chosen as matrix of gel. Through single factor and orthogonal test, the optimal preparation method of resveratrol gel was screened and its content was determined. It was found that the resveratrol gel prepared by the optimized process was bright white, uniform and delicate, and it had good spreadability. |
