摘要

Asafoetida是一种主要从伊朗东部的阿魏(Ferula foetida)中提取的油胶树脂,用于治疗胃痛、胃酸反流、神经系统疾病和呼吸道疾病。Asafoetida因其硫化物及其对呼吸系统疾病的证实作用而引起了研究人员的注意。本研究采用1H NMR (qH NMR)和气相色谱-质谱联用(GC-MS)技术,通过对E/Z-仲丁基丙烯二磺酸和E/Z-(甲基硫)丙烯- 1-丙烯二磺酸这两种关键硫化物的定量分析,评价了F. foetida油胶树脂添加剂的货架稳定性。在qH NMR和GC-MS方法中得到了相似的结果。qH NMR方法在2 ~ 12 mg/mL范围内线性良好,在2.2 ~ 17 mg/mL范围内线性良好,相关系数为0.99,稳定性良好(RSD%≤2.72%)。因此,尽管二硫化合物具有挥发性,但根据结果,qH NMR方法可以被认为是定量含有挥发性成分的补充剂中这些化合物的适当方法,这些挥发性成分在用其他方法分析之前需要额外的提取步骤。

Quantification of Two Sulfide Compounds in Oleo–Gum-Resin Supplement of Ferula foetida Using qH NMR and GC–MS Methods

Quantification of Two Sulfide Compounds in Oleo–Gum-Resin Supplement of Ferula foetida Using qH NMR and GC–MS Methods

Asafoetida is an oleo–gum-resin mainly obtained from Ferula foetida in eastern Iran, which is employed for the treatment of stomachaches, acid reflux, nervous system disorders and respiratory diseases. Asafoetida has attracted the attention of researchers due to its sulfide compounds and their proven effects on respiratory illnesses. In this study, the shelf stability of supplement of F. foetida's oleo–gum-resin by quantifying two key sulfide compounds including E/Z-sec-butyl propenyl disulfane and E/Z-(methylthio)propyl 1-propenyl disulfane was evaluated by 1H NMR (qH NMR) and gas chromatography–mass spectrometry (GC–MS). The similar results were obtained in both qH NMR and GC–MS methods. The qH NMR method showed good linearity in the ranges of 2–12 mg/mL for E/Z-sec-butyl propenyl disulfane and 2.2–17 mg/mL for E/Z-(methylthio) propyl 1-propenyl disulfane with a correlation coefficient of 0.99 and acceptable stability (RSD% ≤ 2.72%) for the quantification of the compounds. Therefore, despite the volatility of disulfide compounds and according to the results, the qH NMR method could be considered adequate method for quantifying these compounds in supplements containing the volatile components that requires extra extraction steps before analyses by other method.

期刊介绍: Flavour and Fragrance Journal publishes original research articles, reviews and special reports on all aspects of flavour and fragrance. Its high scientific standards and international character is ensured by a strict refereeing system and an editorial team representing the multidisciplinary expertise of our field of research. Because analysis is the matter of many submissions and supports the data used in many other domains, a special attention is placed on the quality of analytical techniques. All natural or synthetic products eliciting or influencing a sensory stimulus related to gustation or olfaction are eligible for publication in the Journal. Eligible as well are the techniques related to their preparation, characterization and safety. This notably involves analytical and sensory analysis, physical chemistry, modeling, microbiology – antimicrobial properties, biology, chemosensory perception and legislation. The overall aim is to produce a journal of the highest quality which provides a scientific forum for academia as well as for industry on all aspects of flavors, fragrances and related materials, and which is valued by readers and contributors alike.
