The essential oil and infusion of Salvia officinalis leaves have been widely applied in traditional medicine since ancient times and nowadays subjected to extensive research of their antibacterial, antiviral and cytotoxic properties. This paper shows chemical composition data of S. officinalis leaves essential oil isolated by steam distillation using a Clevenger-type apparatus. Also, the paper presents the chemical content of volatile and semi-volatile compounds of S. officinalis leaves infusion. The volatile and semi-volatile compounds of S. officinalis leaves infusion were isolated by solid-phase extraction (SPE) and liquid-liquid extraction with hexane and dichloromethane. SPE was carried out on 500 mg octadecylsilane (C18) cartridges and elution with dichloromethane. Liquid-liquid extraction was performed with hexane and dichloromethane. The essential oil in dichloromethane and infusion extracts in hexane and dichloromethane were analyzed by gas chromatography coupled with mass spectrometry. The quantitative results obtained by solid-phase extraction and liquid-liquid extraction showed that SPE on C18 performed the highest recovery of the volatile compounds from infusion sample.
鼠尾草叶精油和浸剂自古以来就在传统医学中广泛应用,如今对其抗菌、抗病毒和细胞毒性特性进行了广泛研究。本文展示了使用克莱文杰型装置通过水蒸气蒸馏分离得到的鼠尾草叶精油的化学成分数据。此外,本文还介绍了鼠尾草叶浸剂中挥发性和半挥发性化合物的化学组成。鼠尾草叶浸剂中的挥发性和半挥发性化合物通过固相萃取(SPE)以及用己烷和二氯甲烷进行液液萃取来分离。SPE在500毫克十八烷基硅烷(C18)柱上进行,并用二氯甲烷洗脱。液液萃取用己烷和二氯甲烷进行。二氯甲烷中的精油以及己烷和二氯甲烷中的浸剂提取物通过气相色谱-质谱联用进行分析。通过固相萃取和液液萃取获得的定量结果表明,C18固相萃取对浸剂样品中挥发性化合物的回收率最高。
