AI Article Synopsis
- A quick and effective method was developed to determine the volatile compounds in Semen Ziziphi Spinosae.
- The extraction was done using headspace solid-phase microextraction and analyzed through gas chromatography-mass spectrometry, successfully identifying 116 out of 126 compounds.
- The main volatile components found were primarily alkanes and terpenoids, indicating that this method is accurate and suitable for similar fruit analyses.
Article Abstract
Objective: To establish a rapid and simple method for the determination of volatile constituents in Semen Ziziphi Spinosae.
Methods: The volatile constituents in Semen Ziziphi Spinosae were extracted by head space solid-phase microextraction (HS-SPME) and analysed by GC-MS.
Results: Powder of sample was pre-heated for 30 min at 90 degrees C, then headspace-extracted with 65 microm PDMS/DVB fiber for 50 min. After desorbed for 5 min at 250 degrees C, the separation was well completed on a Rxi -50 capillary column. 126 kinds of volatile compounds were isolated and 116 compounds were identified. The amounts of compound from the volatile constituents were determined by area normalization method. The main components extracted by HS-SPME were alkane (32.08%), terpenoid and derivatives of oxygenated terpenoid (27.06%).
Conclusion: The method is simple, fast and accurate, and it is suitable for the determination of the volatile constituents in fruit of Ziziphus jujuba.
