The shell nacre protein was extracted from the nacre layer in the Pinctada martensti shell by a combined technology of acidification-high pressure, with the extraction process optimized through single-factor and response surface experiments using the protein extraction rate as index. The protease hydrolysis products of the shell nacre protein were then prepared, and evaluated for its amino acid composition, anti-inflammatory activity as well as skin repair activity. The results showed that under the optimal extraction conditions of hydrochloric acid concentration 0.18 mol/L, alkali material-liquid ratio (g∶mL) 1∶4.9, mass fraction of NaOH solution 1.00%, extraction temperature 65 ℃, extraction time 3 h, acid precipitation pH 3.5 and resting time 32 h, the extraction rate of shell nacre protein was 17.31%±0.84%. The enzymatic hydrolysate of the shell nacre protein produced via bromelain hydrolysis for 3 h showed no cytotoxicity and was beneficial to the macrophage proliferation. The inhibitory rate of the hydrolysate with a concentration of 800 μg/mL on NO release reached up to 51.85%±1.39%. Meanwhile, the hydrolysate exhibited activities of inhibition against the pro-inflammatory factors IL-6 and TNF-α, and up-regulation of the anti-inflammatory factor IL-10 release, thus demonstrating good anti-inflammatory performance. The enzymatic hydrolysate of the shell nacre contained 17 kinds of amino acids. Among them, the total relative content of 8 kinds of essential amino acids for the human body was 32.626%, the total relative content of 7 kinds of hydrophobic amino acids was 34.513%, while that of 3 kinds of positively charged amino acids was 16.173%. The shell nacre active peptides could significantly improve cell proliferation and cell migration of fibroblasts L929, and improve cell viability induced by H2O2, inhibit ROS production, and exhibit good skin repair activity.

以马氏珠母贝贝壳珍珠层为原料,采用酸化-高压联用技术提取珍珠层蛋白。以珍珠层蛋白提取率为指标,通过单因素和响应面实验优化了贝壳珍珠层蛋白的提取工艺。经蛋白酶酶解制备了贝壳珍珠层蛋白酶解产物,并对其氨基酸组成、抗炎活性和皮肤修复活性进行了评价。结果表明,在盐酸浓度0.18 mol/L、碱液料液比(g∶mL)1∶4.9、NaOH溶液质量分数1.00%、提取温度65 ℃、提取时间3 h、酸沉pH=3.5、静置时间32 h的最佳提取工艺条件下,贝壳珍珠层蛋白提取率为17.31%±0.84%。以菠萝蛋白酶酶解3 h制备的贝壳珍珠层蛋白酶解产物无细胞毒性且有利于巨噬细胞增殖,质量浓度为800 μg/mL的贝壳珍珠层蛋白酶解产物对细胞NO释放量的抑制率可达51.85%±1.39%,能够抑制促炎因子IL-6和TNF-α释放水平,同时上调抗炎因子IL-10的释放水平,表现出良好的抗炎活性。贝壳珍珠层酶解产物中含有17种氨基酸,其中8种人体必需氨基酸的总相对含量为32.626%,7种疏水性氨基酸的总相对含量为34.513%,3种带正电荷氨基酸的总相对含量为16.173%。贝壳珍珠层酶解产物可显著提高成纤维细胞L929的细胞增殖和细胞迁移,并且可以提高H2O2诱导下的细胞活力,抑制活性氧的产生,表现出良好的皮肤修复活性。

以马氏珠母贝贝壳珍珠层为原料,采用酸化-高压联用技术提取珍珠层蛋白。以珍珠层蛋白提取率为指标,通过单因素和响应面实验优化了贝壳珍珠层蛋白的提取工艺。经蛋白酶酶解制备了贝壳珍珠层蛋白酶解产物,并对其氨基酸组成、抗炎活性和皮肤修复活性进行了评价。结果表明,在盐酸浓度0.18 mol/L、碱液料液比(g∶mL)1∶4.9、NaOH溶液质量分数1.00%、提取温度65 ℃、提取时间3 h、酸沉pH=3.5、静置时间32 h的最佳提取工艺条件下,贝壳珍珠层蛋白提取率为17.31%±0.84%。以菠萝蛋白酶酶解3 h制备的贝壳珍珠层蛋白酶解产物无细胞毒性且有利于巨噬细胞增殖,质量浓度为800 μg/mL的贝壳珍珠层蛋白酶解产物对细胞NO释放量的抑制率可达51.85%±1.39%,能够抑制促炎因子IL-6和TNF-α释放水平,同时上调抗炎因子IL-10的释放水平,表现出良好的抗炎活性。贝壳珍珠层酶解产物中含有17种氨基酸,其中8种人体必需氨基酸的总相对含量为32.626%,7种疏水性氨基酸的总相对含量为34.513%,3种带正电荷氨基酸的总相对含量为16.173%。贝壳珍珠层酶解产物可显著提高成纤维细胞L929的细胞增殖和细胞迁移,并且可以提高H2O2诱导下的细胞活力,抑制活性氧的产生,表现出良好的皮肤修复活性。

The shell nacre protein was extracted from the nacre layer in the Pinctada martensti shell by a combined technology of acidification-high pressure, with the extraction process optimized through single-factor and response surface experiments using the protein extraction rate as index. The protease hydrolysis products of the shell nacre protein were then prepared, and evaluated for its amino acid composition, anti-inflammatory activity as well as skin repair activity. The results showed that under the optimal extraction conditions of hydrochloric acid concentration 0.18 mol/L, alkali material-liquid ratio (g∶mL) 1∶4.9, mass fraction of NaOH solution 1.00%, extraction temperature 65 ℃, extraction time 3 h, acid precipitation pH 3.5 and resting time 32 h, the extraction rate of shell nacre protein was 17.31%±0.84%. The enzymatic hydrolysate of the shell nacre protein produced via bromelain hydrolysis for 3 h showed no cytotoxicity and was beneficial to the macrophage proliferation. The inhibitory rate of the hydrolysate with a concentration of 800 μg/mL on NO release reached up to 51.85%±1.39%. Meanwhile, the hydrolysate exhibited activities of inhibition against the pro-inflammatory factors IL-6 and TNF-α, and up-regulation of the anti-inflammatory factor IL-10 release, thus demonstrating good anti-inflammatory performance. The enzymatic hydrolysate of the shell nacre contained 17 kinds of amino acids. Among them, the total relative content of 8 kinds of essential amino acids for the human body was 32.626%, the total relative content of 7 kinds of hydrophobic amino acids was 34.513%, while that of 3 kinds of positively charged amino acids was 16.173%. The shell nacre active peptides could significantly improve cell proliferation and cell migration of fibroblasts L929, and improve cell viability induced by H2O2, inhibit ROS production, and exhibit good skin repair activity.
