Microwave hydrodiffusion and gravity (MHG) and ethanolic solid-liquid extraction were compared using selected plant sources. Their bioactive profile, color features, and proximate chemical characterization were determined. MHG extracts, commercial antioxidants, and three distinct types of thermal spring water were used in a sunscreen cream formulation. Their bioactive capacity, chemical and rheological properties were evaluated. MHG flower extract provided the highest bioactive properties. MHG liquor exhibited the highest total solid extraction yield. The MHG sample stood out for its total protein content and its monosaccharide and oligosaccharide concentration. acorns divided into quarters supplied MHG extract with the lowest energy requirements, highest DPPH inhibition percentage, total lipid content and the highest enzyme inhibition. The chemical and bioactive capacities stability of the sunscreen creams elaborated with the selected MHG extracts and the thermal spring waters showed a similar behavior than the samples containing commercial antioxidants.
采用选定的植物源，比较了微波水蒸馏扩散法和重力法（MHG）与乙醇固液萃取法。测定了它们的生物活性特征、颜色特征和近似化学特性。在防晒霜配方中使用了 MHG 提取物、商业抗氧化剂和三种不同类型的温泉水。评估了它们的生物活性能力、化学和流变学性质。MHG 花提取物提供了最高的生物活性特性。MHG 酒表现出最高的总固体提取率。MHG 样品的总蛋白含量、单糖和低聚糖浓度最高。将橡子分成四份，为 MHG 提取物提供了最低的能量需求、最高的 DPPH 抑制率、最高的总脂质含量和最高的酶抑制率。用所选的 MHG 提取物和温泉水制备的防晒霜的化学和生物活性稳定性与含有商业抗氧化剂的样品表现出相似的行为。
