identification of (S(S)R(C))-S-n-butylcysteine sulfoxide (1) from the bulbs of Allium siculum is reported. This compound was found in all parts of the plant (bulbs, stem, leaves, and flowers) along with known compounds (S(S)R(C))-S-methyl- and (R(S)R(C))-(E)-S-(1-propenyl)cysteine sulfoxides (2 and 3, respectively). In addition, six n-butyl-containing thiosulfinates (4-9) have been found in a CH2Cl2 extract
据报道,从蒜头葱的鳞茎中分离和鉴定了(S(S)R(C))-Sn-丁基半胱氨酸亚砜(1)。该化合物与已知化合物(S(S)R(C))-S-methyl-和(R(S)R(C))一起存在于植物的所有部位(鳞茎,茎,叶和花)。 -(E)-S-(1-丙烯基)半胱氨酸亚砜(分别为2和3)。此外,在灯泡的CH2Cl2提取物中发现了六种含正丁基的硫代亚磺酸盐(4-9)。通过光谱方法(主要是NMR和MS)的组合,并与通过合成获得的真实化合物进行比较来确定结构。据报道抗菌活性为4-7和9。
