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.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine or natural medicine pharmacy, and in particular relates to a low-polarity component extract of Guangdong Zizhu, a preparation method thereof, a pharmaceutical composition containing the Guangdong Zizhu volatile oil extract and its use for inhibiting cervicitis pathogenic bacteria the use of. Background technique [0002] The World Health Organization's survey of Chinese women shows that the population of women of childbearing age in my country is about 150-200 million, of which about 41% of women suffer from different degrees of gynecological inflammatory diseases, and the incidence rate of married women is as high as 70%. According to statistics, cervicitis accounts for about 40-50% of the total outpatient department of obstetrics and gynecology, ranking first in gynecological diseases, among which chronic cervicitis accounts for 10%-25% of outpatients. Under normal circumstances, the...
