GC-MS Fingerprint Studies
The GC fingerprint performed by gas chromatography with patchouli alcohol and pogostone as chemical markers can be used for identification of patchouli oil. For controlling the quality, standard fingerprint of P.cablin collected from different regions of China was developed by using GC-MS. Nine compounds including beta- patchoulene, caryophyllene, alpha-guaiene, seychellene, beta-guaiene, delta-guaiene, pathulenol, patchouli alcohol and pogostone were identified among 10 main peaks in P. cablin.71
Several experiments were carried out to test different habitats, collection periods, processing methods, the level of spreading manure and using agricultural chemical with the volatile oil assay of pharmacopoeia and GC-MS method. A gas chromatography-tandem mass spectrometry (GC/MS/MS) method has been successfully developed for the determination of patchoulic alcohol content in the samples of dried P. cablin and was found to be convenient in particular to tackle the complicated matrix problems always encountered in the herbs which contain high level of essential oils. The chemical constituents of the volatile oil of the stems and leaves of P. cablin collected from Leizhou county have been analyzed by GC-MS and found patchouli alcohol, delta- guaiene, alpha-guaiene, seychellene, alpha-patchoulene, aciphyllene, trans-caryophyllene as main constituents
