Abstract

In this study we aimed to compare the chemical composition and biological activity between L. leaf extract obtained with 95% / ethanol using a pulsed electric field (PEF) and the conventional maceration method. Extracts of leaves collected from Chiang Mai (CM), Sakon Nakon (SK), and Buriram (BR), Thailand, were investigated for 1-deoxynojirimycin content by high-performance liquid chromatography and for total phenolic content by the Folin-Ciocalteu method. Antioxidant activity was investigated by 2,2'-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis-3-ethylbenzothiazoline-6-sulphonate (ABTS), and ferric reducing antioxidant power (FRAP) assay. Anti-tyrosinase and anti-hyaluronidase activity was investigated by in vitro spectrophotometry. The results show that this is the first study to indicate PEF as a novel method for enhancing the phenolic content and antioxidant, anti-tyrosinase, and anti-hyaluronidase activity of leaf extract ( < 0.05). PEF extract of leaves collected from BR had comparable ABTS scavenging activity to l-ascorbic acid and comparable anti-tyrosinase activity to kojic acid ( > 0.05). On the other hand, PEF extract of leaves collected from SK exhibited significantly high anti-hyaluronidase activity, comparable to that of oleanolic acid ( > 0.05). Therefore, PEF is suggested for further leaf extraction in the production of natural whitening and anti-aging cosmetic ingredients.

摘要

在这项研究中,我们旨在比较使用脉冲电场(PEF)从 95%乙醇中获得的 L.叶提取物与传统浸渍法之间的化学成分和生物活性。我们对来自泰国清迈(CM)、色军(SK)和武里南(BR)的 叶提取物进行了 1-脱氧野尻霉素含量的高效液相色谱分析和总酚含量的福林-酚比色法分析。抗氧化活性通过 2,2'-二苯基-1-苦基肼基(DPPH)、2,2'-联氮-3-乙基苯并噻唑啉-6-磺酸(ABTS)和铁还原抗氧化能力(FRAP)测定法进行研究。通过体外分光光度法研究了对酪氨酸酶和透明质酸酶的抑制活性。结果表明,这是首次表明 PEF 可作为一种增强 叶提取物的酚含量和抗氧化、抗酪氨酸酶和抗透明质酸酶活性的新方法(<0.05)。BR 采集的 叶的 PEF 提取物具有与 l-抗坏血酸相当的 ABTS 清除活性,且具有与曲酸相当的抗酪氨酸酶活性(>0.05)。另一方面,SK 采集的 叶的 PEF 提取物表现出显著高的透明质酸酶抑制活性,与齐墩果酸相当(>0.05)。因此,建议在生产天然美白和抗衰老化妆品成分时进一步使用 PEF 进行 叶提取。
