The chloroform extract of mustard leaves (Brassica juncea Cosson) reduced mutagenicity of $AFB_1$ in bacterial assay (Salmonella typhimurium TA100). 4-Decanol was one of major compounds in the chloroform extract when analyzed by GC-MS on HP-5 capillary column. The authentic compound of 4-decanol dissolved in DMSO (0.5%) inhibited mutagenic activities of $AFB_1$ and MNNG in Salmonella typhimurium TA100 at a rate of 99% and 93%, respectively. This result indicates that 4-decanol is an antimutagenic compound present in chloroform extract of mustard leaves.

Seed mustard is high in nutrient quality and grows continuously under cold condition. Accordingly, it possessess high potential to bring about more efficient use of land when it is grown as a seasonings crop at paddy field in winter season. Recently, Seed mustard has aroused people‘s interest as a catch crop. The purpose of this trial is to examine productivity and chemical components of seed mustard and to select suitable variety in the southern area of Korea. Seed-mustard cv. Yeongsanpo local showed higher seed yield than any other varieties used in the experiment. It showed relatively high content of Oil, Protein, Ash, Carbo, $P_2O_5$, $K_2O$, Ca and T-N. The heritabilities of all the characters were estimated to be high. Therefore, it was concluded that Youngsanpo local was the most suitable variety with high yield and high nutrient quality at the southern area of Korea.

The objective of this study was to compare the anticancer activity of glucosinolates against four different cancer cells; SNU-251, SNU-354, SNU-C4, MCF-7 and to determine the amounts of glucosinolates in mustard leaves. Green and red mustard leaves were cultivated on the field of Rural Development Administration from May to July, 2010. After the leaves were harvest and lypophilized, the fine powder was extracted with boiling 70% methanol(v/v) for the measurement of anticancer activity and then applied to the cancer cells obtained from Korean Cell Line Bank(KCLB). The anticancer activity of red leaf mustard was higher than that of green mustard leaf, particularly in SNU-251 for 24 hr and in SNU-C4 for 48 hr. In both green and red mustard leaf, sinigrin was the most abundant glucosinolte and was determined as 4.71 and 3.06 mg/g dry wt., respectively, but glucoiberin only presented 0.14 mg/g dry wt. with minor amounts.
