sulforaphane-related compounds were positively identified in the chloroform extract, of which 5-methylsulfinylpentylnitrile was found in the greatest concentration (475.7 mg/kg of fresh sprouts), followed by sulforaphane (222.6 mg/kg) and 4-methylsulfinylbutylnitrile (63.0 mg/kg). Among 18 sulforaphane and related compounds synthesized (6 amines, 6 isothiocyanates, and 6 nitriles), 2 amines, 6 isothiocyanates, and
从新鲜西兰花芽中制得的粗甲醇提取物依次用己烷,氯仿,乙酸乙酯和丁醇提取。从残余水层获得残余水部分。幽门螺杆菌有最大的抑制区(> 5 cm)依次用氯仿萃取液,己烷萃取液(5.03 cm),乙酸乙酯萃取液(4.90 cm),丁醇萃取液(3.10 cm)和粗甲醇萃取液(2.80 cm)显示任何抑制区。包括萝卜硫烷在内,在氯仿提取物中鉴定出了五种与萝卜硫烷相关的化合物,其中5-甲基亚磺酰基戊基腈的浓度最高(新鲜芽苗为475.7 mg / kg),其次是萝卜硫烷(222.6 mg / kg)和4-甲基亚磺酰基丁基腈。 (63.0 mg / kg)。在合成的18种萝卜硫烷和相关化合物(6种胺,6种异硫氰酸盐和6个腈)中,有2种胺,6种异硫氰酸盐和1个腈对幽门螺杆菌的抑制区大于5厘米拉紧。结果表明,西兰花芽可以作为药用物质的极佳食物来源。
