Embodiment 1
[0075] Example 1: Preparation of cypress extract
[0076] 1.1 SFC extraction: take 288g of shelled cypress seeds and pulverize them in SFC (SFC instrument model HA221-40-11, Jiangsu Nantong Huaan Supercritical Extraction Co., Ltd.), extraction conditions: extraction kettle temperature: 32°C, extraction kettle temperature and pressure: 25MPa ; Separation kettle temperature: 38°C, separation kettle temperature and pressure: 6MPa; supercritical CO 2 Flow rate; 30-40L / h; extraction time: 1.5h. Deborah seed extract BZ-1-SFC 23.2g, the yield is 8.0wt%.
[0077]1.2 Petroleum ether extraction: Take 5.2 g of shelled cypress seeds and crush them into a 500 ml conical flask, add 250 ml of petroleum ether, and extract by ultrasonic 3 times, 1 hour each time. The petroleum ether extracts were combined and distilled under reduced pressure to obtain 1.2 g of active site BZR-1-PE, with a yield of 23.1 wt%.
Embodiment 2
[0082] Example 2: Determination of the content of helichanoid-type diterpenes araucic acid and 13-epicupressic acid in cypress or cypress seed extract
[0083] 2.1. Separation and purification of helichranoid diterpenes imbricatolic acid and 13-epicupressic acid in cypress seed extract:
[0084] According to the method of literature (Wang YZ. et al., Phytochemistry, 2008, 69, 518-526.), the dried cypress kernels (10.2 kg) were crushed, and then extracted with 95wt% industrial ethanol (20L×3) at room temperature. 81.8 g of the compound imbricatolic acid was obtained by means of column chromatography with a yield of 8.2 wt%; 2.54 g of the compound 13-epicupressic acid was obtained. The spectral data of the compounds araucic acid and 13-epicupressic acid are as follows:
[0085] Araucic acid, imbricatolic acid
[0086] white powder, [α] D (20℃)+50(c 1.5, CHCl3); 1 H-NMR (CDCl 3 ,300MHz):δ0.60(3H,s,CH 3 -20),0.90(3H,d,J=6.4Hz,CH 3 -16),1.22(3H,s,CH 3 -18),3.68(2H,m,H-15),4...
Embodiment 3
[0103] Example 3: Determination of Nootropic Activity of Bozi / Bozi Ren extract series
[0104] Comparison of the improving effects of Baizi / Banziren extract series and marketed health product fish oil on scopolamine-induced memory impairment in mice
[0105] 3.1 Experimental animals
[0106] KM mice, 24-30g for both sexes.
[0107] 3.2 Sample Information
[0108] The SFC extract (BZ-1-SFC), the SFC extract (BZR-SFC), the petroleum ether extract (BZR-PE), and the ethanol extract (BZR-E) were all performed according to Example 1. The method in 2 was obtained from the extraction of cypress seeds; fish oil was purchased from General Nutrition Corporation, GNC, USA.
[0109] 3.3 Experimental equipment
[0110] Channel type mouse water maze (80cm×50cm×20cm)
[0111] 3.4 Sample processing
[0112] 1) Compounds were dissolved in a 20 wt% glycerol aqueous solution. Except for BZR-E, which was measured at a concentration of 20 mg / kg, the other five compounds were all measured at a...
