Examples
Embodiment 1
[0037] Example 1: Supercritical CO at the low polarity part of Guangdong Zizhu 2 preparation
[0038] Guangdong Zizhu medicinal material is crushed, 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: extraction temperature is 45°C, pressure 25Mpa; separation kettle temperature is 50°C, pressure 8Mpa ;CO 2 Flow rate 50L / h, total flow 100L; extraction time 2h. The extract from the separation kettle was collected, and the extract was a brown-yellow oily substance. The sample in the separation kettle was extracted with anhydrous ether, and dehydrated with an appropriate amount of anhydrous sodium sulfate to obtain a sample with a yield of 1.042%.
Embodiment 2
[0039] Example 2: Supercritical CO at the low polarity part of Guangdong Zizhu 2 preparation
[0040] Guangdong Zizhu medicinal material is crushed, 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: extraction temperature is 35°C, pressure 25Mpa; separation kettle temperature is 30°C, pressure 5.7 Mpa; CO 2 The flow rate is 50L / h, the total flow rate is 100L; the extraction time is 1.5h. Collect the extract from the separation tank, the extract is a light yellow liquid sample, extract the sample from the separation tank with n-hexane, dehydrate with an appropriate amount of anhydrous sodium sulfate to obtain the sample, and the yield is 0.658%.
Embodiment 3
[0041] Embodiment 3: GC-MS analysis of the chemical composition of the Guangdong purple pearl low polarity component extract obtained in embodiment 1
[0042] 1) GC-MS chromatographic conditions
[0043] Chromatographic column HP-5 capillary column (30m×0.25mm×0.25μm); high-purity nitrogen is used as the carrier gas, the temperature of the injection port is 300°C, the injection method is split injection, the split ratio is 30:1, the injection volume is 1μl, and the Gas flow rate 1.0ml / min; temperature program: initial temperature 200°C, keep for 3min, then rise to 250°C at 4°C / min, keep for 5min, then rise to 300°C at 20°C / min, keep for 3min. The mass spectrometry interface temperature is 310°C, the EI source temperature is 200°C, the electron bombardment energy is 60eV, the scanning range is m / z 25-550amu, all ion scanning, the acquisition delay is 5.0min, and the relative content is calculated by the normalization method.
