京都的传统蔬菜是在京都市附近有限的地区种植的一组独特的蔬菜。比较了京都传统蔬菜和普通蔬菜提取物对紫外线诱变大肠杆菌的生物抗突变性。coli B/r WP 2.在京都的传统蔬菜中，卡莫茄子（茄科）和卡莫东方腌瓜（葫芦科）在正己烷、氯仿和乙酸乙酯萃取物中表现出比普通蔬菜对应物更高的生物抗突变性和产量。南瓜氯仿和乙酸乙酯部位具有抗突变活性，而普通南瓜不具有抗突变活性。已知植物乙酸乙酯部分中的多酚化合物与抗突变性有关。然而，本蔬菜的抗突变性的强度与乙酸乙酯组分中的多酚含量无关。特别是，卡莫茄子具有多酚和非多酚的生物抗突变的乙酸乙酯馏分中的亚馏分。在水相部分，芋头（芋科）是我们的样品中最有能力，无论是普通或传统的起源。因此，它被认为，在京都的一些传统蔬菜是上级的普通蔬菜在其生物抗突变性，这些可以被用作起始材料，以确定新的生物抗突变剂。
Traditional vegetables in Kyoto are a unique group of vegetables that have been cultivated in limited areas near Kyoto city. We compared the traditional vegetables in Kyoto with common vegetables for the bio-antimutagenicity of their extracts against UV-induced mutation of E. coli B/r WP2. Among the traditional vegetables in Kyoto, Kamo eggplant (Solanaceae) and Katsura oriental pickling melon (Cucurbitaceae) showed higher bio-antimutagenicity and yield in the n-hexane, chloroform and ethyl acetate fractions than their common vegetable counterparts. Shishigatani pumpkin (Cucurbitaceae) possessed bio-antimutagenicity in the chloroform and ethyl acetate fractions, but common pumpkin did not. Polyphenolic compounds in the ethyl acetate fraction of plants are known to be related to antimutagenicity. However, the intensity of bio-antimutagenicity was not correlated with the polyphenol content in the ethyl acetate fractions of the present vegetables. In particular, Kamo eggplant possessed both polyphenolic and non-polyphenolic bio-antimutagenic sub-fractions in the ethyl acetate fraction. In the aqueous fraction, taro (Dioscoreaceae) was the most capable among our samples, whether being of common or traditional origin. Consequently, it is considered, that some traditional vegetables in Kyoto are superior to common vegetables in their bio-antimutagenicity and that these could be used as starting materials to identify new bio-antimutagens.
