Abstract:
To provide a scientific evidence for the initial primary processing method, an ultra-high performance liquid chromatography combined with a triple quadrupole electrospray tandem mass spectrometry (UPLC-MS/MS) was used to analyze the contents variation of catechins, flavonoids, flavonoid glycosides, biflavones, terpene lactones and phenolic acids during the process of drying in the sun, in the shade, and baked with 35, 45, 60, 80 degrees C, respectively. The results show that drying in the 80 degrees C is conducive to the accumulation of catechins, flavonoid glycosides, terpene lactones, better than the effects of other procedures. Therefore, the fast drying at 80 degrees C is beneficial for the retention of various types of active ingredient of Ginkgo biloba, and this method could be applied as a preferably dry processing.
