Recipes on the composition of the "salad of the monks" (Capuchin monks) have been reported in Italy since the 17th century. Different wild edible plants were highly regarded as an important ingredient of this mixed salad. Among these, some species played a key role for both their taste and nutritional properties: L. (PC), L., L., and L. In the present study, the micromorphological and phytochemical features as well as the antioxidant and anti-inflammatory properties of extracts of these fresh and blanched leaves, were investigated. The extracts obtained by blanched leaves, according to the traditionally used cooking method, showed the highest content of bioactive compounds (total phenols 1202.31-10,751.88 mg GAE/100 g DW; flavonoids 2921.38-61,141.83 mg QE/100 g DW; flavanols 17.47-685.52 mg CE/100 g DW; proanthocyanidins 2.83-16.33 mg CyE/100 g DW; total chlorophyll 0.84-1.09 mg/g FW; carbohydrates 0.14-1.92 g/100 g FW) and possess the most marked antioxidant (IC 0.30-425.20 µg/mL) and anti-inflammatory activity (IC 240.20-970.02 µg/mL). Considering this, our results indicate that increased consumption of the investigated plants, in particular of PC, raw or cooked briefly, could provide a healthy food source in the modern diet by the recovery and enhancement of ancient ingredients.
自17世纪以来,意大利就有关于“僧侣沙拉”(嘉布遣会修士)成分的食谱报道。不同的野生可食用植物被高度视为这种混合沙拉的重要成分。其中,一些物种因其味道和营养特性发挥了关键作用:L.(PC)、L.、L.和L.。在本研究中,对这些新鲜和焯烫叶片提取物的微观形态和植物化学特征以及抗氧化和抗炎特性进行了研究。按照传统烹饪方法从焯烫叶片中获得的提取物显示出最高的生物活性化合物含量(总酚1202.31 - 10751.88毫克没食子酸当量/100克干重;黄酮类化合物2921.38 - 61141.83毫克槲皮素当量/100克干重;黄烷醇17.47 - 685.52毫克儿茶素当量/100克干重;原花青素2.83 - 16.33毫克表儿茶素当量/100克干重;总叶绿素0.84 - 1.09毫克/克鲜重;碳水化合物0.14 - 1.92克/100克鲜重),并具有最显著的抗氧化(IC50 0.30 - 425.20微克/毫升)和抗炎活性(IC50 240.20 - 970.02微克/毫升)。考虑到这一点,我们的结果表明,增加对所研究植物的消费,特别是生食或短暂烹饪的PC,通过恢复和强化古老成分,可以在现代饮食中提供一种健康的食物来源。
