摘要

芸苔菜对改善健康的有益作用部分归因于其中存在各种形式的植物化学物质和抗氧化剂,例如抗坏血酸、类胡萝卜素和包括类黄酮和叶绿素在内的多酚化合物。对两种芸苔属蔬菜,即西兰花(Brassica oleracea)和甘蓝(Brassica oleraceae .var acephala)进行了有机种植和常规种植的植物化学物质含量分析。有机西兰花和甘蓝的抗坏血酸含量分别为89.67±0.33和48.67±0.33 mg/100g,高于无机西兰花和甘蓝的84.80±0.40和43.33±0.67 mg/100g。有机西兰花的β -胡萝卜素含量为11.17±0.01 ppm,高于无机西兰花的8.71±0.01 ppm。叶绿素含量以无机西兰花(5.87±0.03 mg/L)和羽衣甘蓝(8.31±0.01 mg/L)较高。有机羽衣甘蓝中单质酚和类黄酮含量高于无机羽衣甘蓝。无机西兰花和羽衣甘蓝中的总酚、单宁和草酸盐含量较高。西兰花和羽衣甘蓝都是产热化学物质的好来源。从研究结果中得出结论,它们富含促进健康的植物化学物质,因此应该被纳入我们的食物篮子中,以预防各种疾病,特别是癌症。应促进西兰花和羽衣甘蓝的种植和消费,充分发挥其促进健康和保健的有益作用。叶类蔬菜的植物化学成分作为食物的补充,也有可能改善其使用者的健康状况,因为存在对身体健康至关重要的各种化合物。

Health Promoting Bioactive Phytochemicals Present in Organically and Conventionally Grown Exotic Brassica Vegetables
The beneficial effects of Brassica vegetables on health improvement have been partly attributed to the presence of various forms of phytochemicals and antioxidants present in it, e.g. ascorbic acid, carotenoids and polyphenol compounds including flavonoids and chlorophyll. Two Brassica vegetables viz. broccoli (Brassica oleracea) and kale (Brassica oleraceae l.var acephala) which, grown organically and conventionally were analysed for their phytochemicals content. The ascorbic acid content of organically grown broccoli and kale was 89.67±0.33 and 48.67±0.33 mg/100g which was comparatively higher when compared with inorganic counterparts with 84.80±0.40 and 43.33±0.67 mg/100g values respectively. The beta carotene content was found to be higher in case of organic broccoli i.e. 11.17±0.01 ppm as compared to 8.71±0.01 ppm in inorganic broccoli. The chlorophyll content was higher in case of inorganic broccoli (5.87±0.03 mg/L) and kale (8.31±0.01 mg/L). Simple phenol and flavanoids were found to be higher in case of organic kale as compared to inorganic kale. Total phenols, tannins and oxalates were found to be higher in inorganic broccoli and kale. Both broccoli and kale were good sources of pytochemicals. From the findings of the study concluded that they are rich in health–promoting phytochemicals so should be included in our food basket to provide protection against various diseases especially cancer. The cultivation and consumption of broccoli and kale should be promoted to harness their health promoting and health protecting beneficial effects. The phytochemical contents of the leafy vegetables serve as supplements for food and also have the potential to improve the health status of its users as a result of the presence of various compounds vital for good health.
