Abstract
Chinese Kale (Brassica oleracea L. var. Alboglabra) for the Cruciferae (Brassicaceae) Brassica plant in Asia Chinese vegetables commonly consumed in China, Guangdong, Guangxi and Fujian provinces cultivated quite . Department of Taiwan''s main cultivars introduced from China or Southeast Asia, cultivation all over. Carex species generally contain glucosinolates, its degradation products with anti-cancer properties. In this experiment, combined with solid phase micro extraction GC-MS measurement of isothiocyanates in Taiwan’s Chinese kale types of content, that the eight varieties Chinese kale and commercial kale development at all during the harvest season or different, and the resulting. The main ingredients isothiocyanate Allyl ITC ,3-Butenyl ITC ,4-Methylpentyl ITC, n-Pentyl ITC and 2-Phenylethyl ITC and other five, all varieties contain isothiocyanates leaves begin with 3 - Butenyl ITC has the highest relative content. Allyl ITC as the degradation products of sinigrin in Chinese kale, Allyl ITC compared to other types of isothiocyanates and its content is low. Chinese kale at different growth stages, the isothiocyanates that are different types of content, tests ''Chui Po'' not detected at 30 days, isothiocyanates, and 45 days when the plants start bolting, leaves and Moss flowers were measured Allyl ITC ,3-Butenyl ITC ,4-Methylpentyl ITC and other isothiocyanates 3. Kale isothiocyanates in different organs of different types of content, ''Chui-chun,'' and ''Chui Po'' flower moss in the relative content of isothiocyanates higher than the leaves, ''Chui-chun,'' root type isothiocyanate more than the leaves and stems. Insect chewing off leaves, isothiocyanates and relative species were significantly lower than healthy leaves. Chinese kale at different developmental stages within the sulfur content of glycoside types are constantly changing, Moss spent time in the pumping sulfur glycoside content of leaves decreased, flowers moss contains a relatively high content of isothiocyanates, which may be the main cause feeding insects aversion.
