Embodiment 1
[0037] Example 1: Supercritical CO at the low polarity site of Guangdong Zizhu 2 preparation
[0038] Guangdong Zizhu medicinal materials were pulverized, passed through a 24-mesh sieve, weighed 200g, placed in a supercritical 1L extraction kettle (extraction kettle II), and extracted according to the following conditions: the extraction temperature was 45°C, the pressure was 25Mpa; the temperature of the separation kettle was 50°C, and the pressure was 8Mpa ;CO 2 The flow rate is 50L / h, the total flow is 100L; the extraction time is 2h. The extract of the separation kettle was collected, and the extract was a brownish yellow oil. The sample of the separation kettle was extracted with anhydrous ether, and an appropriate amount of anhydrous sodium sulfate was dehydrated to obtain the sample, and the yield was 1.042%.
Embodiment 2
[0039] Example 2: Supercritical CO at the low polarity site of Guangdong Zizhu 2 preparation
[0040] Guangdong Zizhu medicinal materials were pulverized, passed through a 24-mesh sieve, weighed 200g, placed in a supercritical 1L extraction kettle (extraction kettle II), and extracted according to the following conditions: the extraction temperature was 35°C, and the pressure was 25Mpa; the separation kettle temperature was 30°C, and the pressure was 5.7 Mpa; CO 2 The flow rate is 50L / h, the total flow is 100L; the extraction time is 1.5h. The extract from the separation kettle was collected, and the extract was a light yellow liquid sample. The sample from the separation kettle was extracted with n-hexane, and an appropriate amount of anhydrous sodium sulfate was dehydrated to obtain a sample with a yield of 0.658%.
Embodiment 3
[0041] Example 3: GC-MS analysis of the chemical constituents of the Guangdong Zizhu low-polar constituent extract obtained in Example 1
[0042] 1) GC-MS chromatographic conditions
[0043] Chromatographic column HP-5 capillary column (30m×0.25mm×0.25μm); high-purity nitrogen gas as carrier gas, injection port temperature 300℃, injection mode split injection, split ratio 30:1, injection volume 1μl, load Air flow rate 1.0ml / min; temperature program: the initial temperature was 200°C, maintained for 3min, then increased to 250°C at 4°C / min, maintained for 5min, then increased to 300°C at 20°C / min for 3min. The mass spectrometer interface temperature was 310 °C, the EI source temperature was 200 °C, the electron bombardment energy was 60 eV, the scanning range was m / z 25-550 amu, the whole ion scan, the acquisition delay was 5.0 min, and the relative content was calculated by the normalization method.
