The removal of residual captan in carrot and kale by storage temperatures and the addition of condiments was investigated. The quantities of residual captan after sticking and drying of captan in carrot and kale were 0.958 and 26.12 ppm, respectively. During storage of 20 days at 15, 3 and -17℃, the levels of the residual captan in carrot decreased to 0.008 (removal rate: 99.2%), 0.228(76.2%) and 0.380 ppm (60.3%), and those in kale decreased to 1.21 (95.4%), 7.72 (70.5%) and 15.06 ppm (42.3%), respectively. The higher removal rate of residual captan was observed at the higher storage temperatures. When the condiments of soy sauce, green onion, garlic and vinegar added to the carrot which contaminated with the captan and then stored at 15℃ for 24hrs, the residual levels of captan decreased to 0.207 (removal rate: 78.4%), 0.196 (79.5%), 0.164 (82.8%) and 0.209 ppm (78.2%), respectively, showing the garlic was the most effective. However, the residual levels in kale were 2.27 (91.3%), 12.70 (51.4%), 16.42 (37.1%) and 13.70 ppm (47.5%), respectively under the same condition, indicating the soy sauce was the most effective. The removal rates of residual captan in carrot and kale were significantly higher with the addition of the condiments than those of the controls that without the condiments.

Banaba, Lagerstroemia speciosa (L.) Pers. (Lythraceae) is a tree that grows in the tropic islands of the Pacific. This plants are used for medical purposes in the world. The components of L. speciosa were analyzed for the contents according to growing stages at leaves. The distributions of the corosolic acid (2α , 3β -dihydroxyurs-12-en-28-oic acid), phytol, campestrol, and vitamin E were rich among samples in this study. These were contained much fatty acids. The mean content of palmitic acid was from 2.4% across all growing stages, varying from 2.15% for young leaves with the lowest content and 2.86% for fallen leaves with the highest content. Oleic acid, linoleic acid, and linolenic acid were contained nearly mean 2.0% in all leaves of banaba. Our results have shown that the phytochemical profile of young L. speciosa leaves differs quite radically from that of old L. speciosa leaves. In addition, these subdividing results according to plant growth should allow future researches to conduct targeted experimental studies and use of particular medical components of interest, examining chemical variation on the inter-developmental levels.
