Fruit extracts of Dithyrea wislizenii were analyzed for desulfoglucosinolates and intact glucosinolates using HPLC-APCI-MS and HPLC-ESI-MS, respectively. 2-Propenylglucosinolate (sinigrin) was shown to be present in the extracts. 6-Methylsulfanylhexyl- (glucolesquerellin 9), 6-methylsulfinylhexyl- (glucohesperin 10), 7-methylsulfanylheptyl- (11), and 5-methylsulfanylpentylglucosinolate (glucoberteroin 12) were isolated from the extracts and characterized by NMR and MS data. 7-Methoxyglucobrassicin was not detected in D. wislizenii extracts.
利用高效液相色谱-大气压化学电离质谱（HPLC-APCI-MS）和高效液相色谱-电喷雾质谱（HPLC-ESI-MS）分别对节节麦果实提取物中的硫代葡萄糖苷和完整葡萄糖苷进行了分析。结果表明，提取物中存在丙烯基葡萄糖苷（黑芥子苷）。从提取物中分离出 6-甲硫基己基-（葡萄糖芥醇 9）、6-甲亚磺酰基己基-（葡萄糖庚腈 10）、7-甲硫基庚基-（11）和 5-甲硫基戊基葡萄糖苷（葡萄糖-berteroin 12），并通过 NMR 和 MS 数据进行了表征。在节节麦提取物中未检测到 7-甲氧基葡萄糖芸薹素。
