摘要:为了评价草莓叶水提物(SLWE)延缓皮肤衰老功效,对 SLWE 成分、抗氧化活性、抑制非酶糖基化(NEG)
能力进行了测定;探讨了 SLWE 对人包皮成纤维细胞(HFF-1)细胞活率、HFF-1 中透明质酸(HA)、人Ⅰ型胶
原蛋白(COLⅠ)、羟脯氨酸(HYP)、人基质金属蛋白酶 1(MMP-1)、人基质金属蛋白酶 9(MMP-9)含量的
影响。在中波紫外线(UVB)致 HFF-1 损伤模型基础上,考察了 SLWE 对保护组活性氧(ROS)、丙二醛(MDA)、
MMP-1 和超氧化物歧化酶(SOD)的影响,探讨 SLWE 对 UVB 致 HFF-1 损伤保护机制。结果表明,SLWE 富
含 V C 、槲皮素、绿原酸、没食子酸及儿茶素类物质,其中,槲皮素含量 12.86 mg/L,表儿茶素含量 10.13 mg/L。

SLWE 自由基清除能力良好,清除不同自由基能力依次为 O 2 •>DPPH•>ABTS•>亚铁离子螯合>•OH;体积分数为
1%的 SLWE 水溶液对 NEG 的抑制率为 87.17%;体积分数大于 3%的 SLWE 水溶液可提高 HFF-1 中 HA、COLⅠ
和 HYP 含量(p<0.05),体积分数为 6%的 SLWE 水溶液可降低 MMP-1 含量(p<0.01),表明 SLWE 具有提升皮
肤含水量,增加胶原含量,抑制胶原降解,实现延缓衰老的功效;SLWE 可有效降低因 UVB 刺激而产生的 ROS,
体积分数 6%的 SLWE 水溶液可显著降低 MDA 含量,抑制 MMP-1 表达,提高 SOD 活力,说明 SLWE 有助于
缓解氧化应激造成的细胞损伤。

Abstract: In order to evaluate the anti-aging effect of strawberry (Fragaria × Ananassa) leaves water
extract (SLWE), the composition, antioxidant activity and non-enzymatic glycation (NEG) inhibition rate of
SLWE were measured. The effects of SLWE on cell viability and contents of hyaluronic acid (HA), human
collagen type Ⅰ (COL Ⅰ), hydroxyproline (HYP), matrix metalloproteinase 1 (MMP-1) and matrix
metalloproteinase 9 (MMP-9) of human foreskin fibroblasts (HFF-1) were discussed. Based on the UVB
induced damage model of HFF-1, the effects of SLWE on reactive oxygen species (ROS), malondialdehyde
(MDA), MMP-1 and superoxide dismutase (SOD) in the protection group were investigated, and the
protective mechanism of SLWE on UVB-induced HFF-1 damage was explored. The results showed that
SLWE was rich in V C, quercetin, chlorogenic acid, gallic acid and catechins, among which, quercetin and
epicatechin contents were 12.86 mg/L and 10.13 mg/L respectively. SLWE had excellent free radical
