摘要

自由基的增加会对身体的细胞和组织造成损害。这是由于体内缺乏抗氧化能力造成的,所以需要体外的抗氧化剂。其中一种可以作为抗氧化剂来源的植物是黄天鹅绒叶(Limnocharis flava),它含有一类多酚化合物。这种植物的粗提取物还含有其他成分,这些成分不包括在多酚化合物中。本研究旨在测定黄丝叶植物(L. flava)纯化前后的总多酚和类黄酮含量及抗氧化活性。提纯过程采用固相萃取法进行。采用2,2-二苯基-1-苦味酰肼(DPPH)法测定其抗氧化活性。纯化后总多酚和类黄酮含量增加。因此,纯化提取物的抗氧化活性也比粗提取物有所提高。结果表明,该纯化工艺成功地提高了黄丝叶植物中多酚类化合物的含量和抗氧化活性。因此,纯化的提取物可以用作天然抗氧化剂的替代来源,并且可以开发为食品补充成分。

Total Polyphenols and Antioxidant Activity of Yellow Velvetleaf (Limnocharis flava) Extract
An increase in free radicals can cause damage to cells and tissues in the body. This is caused by a lack of antioxidant ability in the body, so it requires antioxidants outside the body. One of the plants that can be used as a source of antioxidants is the yellow velvetleaf (Limnocharis flava), which has a class of polyphenolic compounds. The crude extract of this plant still has other components that are not included in the polyphenol compound. This study aimed to measure the total polyphenol and flavonoid contents as well as the antioxidant activity of the yellow velvetleaf plant (L. flava) before and after purification. The purification process is carried out using the solid-phase extraction method. The antioxidant activity was determined by using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. The total polyphenol and flavonoid contents increase after the purification process. Therefore, the antioxidant activity of purified extract is also increased when compared to crude extract. These results show that the purification process successfully increased the levels of polyphenol compounds from the yellow velvetleaf plant and its antioxidant activity. Thus, the purified extract can be used as an alternative source of natural antioxidants and can be developed as a food supplement ingredient.
