苦瓜等91种食用植物抗促癌作用的研究

POSSIBLE ANTI TUMOR PROMOTING PROPERTIES OF SOME EDIBLE PLANTS

方法：采用ＥＢ病毒早期抗原（ＥＢＶ－ＥＡ）诱导抑制实验的方法，对包括１６个科‘、９１种食用植物（其中大部分为中国常用蔬菜），共计３０２个样品的防癌抗促癌活性进行了检测。结果：７４个样品（占总数的２４．５％）显示出强抑制活性，１３５个样品（占总数的４４．４％）显示出中等抑制活性，其中唇形花科（Ｌａｂｉａｔａｅ）的蔬菜样品８７．５％显示了强抑制活性。紫苏、羽衣甘兰、苦瓜种子、苋菜及山药等，即使在低浓度下也表现出较强的抑制活性；一些中国原产的十字花科蔬菜，如：芥菜、红菜苔、独行菜等，也表现了很高的抑制率。结论：抗促癌物质广泛存在于中国蔬菜之中，抗促癌活性因蔬菜的种类、品种、植物部位、提取溶剂及成熟程度而异，且与栽培的环境条件有关。

Three hundred and two samples of edible plants, including 16 families, 91 kinds, most of which were common Chinese vegetables, were tested for EBV activation inhibitory activity in Riji cells. As a result, the strong activity was mostly found in the vegetables of Labiatae of 87.5%(14/15). The perilla, broccoli, some seed of bitter gourd, amaranth and yam showed strong activities, even at low concentration. Especially, some vegetables of Cruciferae, which are indigenous in China, also showed high inhibitory rate, such as mustard, red flowering Chinese cabbage and garden cress. The result suggested that anti tumor promoters existed in wide varieties of Chinese vegetables.
