This study evaluated the biological properties of lemongrass () extracts. The EtOAc extract of lemongrass had DPPH, TEAC, and nitric oxide-scavenging activity assay results of 58.06, 44.14, and 41.08% at the concentration of 50, 10, and 50 μg/ml, respectively. The EtOAc extract had higher elastase and collagenase inhibitory activities than the 80% MeOH, n-hexane, BuOH, and water extracts and comparable whitening activity toward monophenolase or diphenolase. Also, the EtOAc fraction had higher lipase inhibitory and antimicrobial activities against among extracts which is known to an important contributor to the progression of inflammatory acne vulgaris, and an opportunistic pathogen present in human skin. Total phenolic and flavonoid concentrations in the EtOAc extract were 132.31 mg CAE/g extract and 104.50 mg NE/g extract, respectively. Biologically active compounds in lemongrass extracts were analyzed by LC-MS. This study confirms that lemongrass extracts have potential use as cosmetic skincare ingredients. Thus, lemongrass can be considered a promising natural source of readily available, low-cost extracts rich in antioxidant, skincare, and antimicrobial compounds that might be suitable for replacing synthetic compounds in the cosmeceutical industry.
本研究评估了柠檬草()提取物的生物学特性。柠檬草的 EtOAc 提取物在 50、10 和 50 μg/ml 浓度下,对 DPPH、TEAC 和一氧化氮清除活性测定的结果分别为 58.06%、44.14%和 41.08%。EtOAc 提取物对弹性蛋白酶和胶原酶的抑制活性高于 80%MeOH、正己烷、BuOH 和水提取物,并且对单酚酶或二酚酶具有相当的美白活性。此外,EtOAc 馏分对脂肪酶具有更高的抑制活性和抗菌活性,这是导致炎症性寻常痤疮进展的重要因素,也是人类皮肤中存在的机会性病原体。EtOAc 提取物中的总酚和类黄酮浓度分别为 132.31 mg CAE/g 提取物和 104.50 mg NE/g 提取物。通过 LC-MS 分析了柠檬草提取物中的生物活性化合物。本研究证实,柠檬草提取物具有作为化妆品护肤成分的潜力。因此,柠檬草可以被认为是一种有前途的天然来源,其提取物富含抗氧化剂、护肤和抗菌化合物,可能适合替代化妆品行业中的合成化合物。
