Embodiment 1
[0012] Example 1 Extraction and Preparation of Panax notoginseng Saponins
[0013] Alcohol extraction, centrifugation, macroporous resin, concentration, drying and pulverization methods are used to obtain an extract of effective active ingredients of Panax notoginseng flower buds with stable transfer rate and yield and high purity. After color development by the vanillin-glacial acetic acid method, the ultraviolet spectrophotometry (UV) is detected at 548nm, and the weight percent content of the total saponins of the notoginseng flower buds in the extract accounts for 50%-100% of the total weight of the extract.
Embodiment 2
[0014] Example 2: Antihypertensive effect experiment of Panax notoginseng saponins on spontaneously hypertensive rats
[0015] 1. Select 18-week-old SHR rats and WKY rats (purchased from Shanghai Institute of Hypertension)
[0016] 2. Experimental grouping:
[0017] Normal WKY group (0.9% NS duodenum administration);
[0018] SHR rats were divided into blank group (0.9% NS duodenum administration);
[0019] Panax notoginseng total saponins low-dose group (0.8g / kg duodenum administration of Panax notoginseng total saponins);
[0020] The middle dose group of total saponins of Panax notoginseng flower buds (1.6g / kg duodenum administration of total saponins of Panax notoginseng flower buds);
[0021] Panax notoginseng total saponins high-dose group (3.2g / kg duodenum administration of Panax notoginseng total saponins);
[0022] Nifedin group (nifedin 5mg / kg duodenal administration).
[0023] 3. Acute antihypertensive test:
[0024] Each group was anesthetized with 2% sodium ...
Embodiment 3
[0029] Example 3: Effect test of Panax notoginseng saponins on the proliferation of vascular smooth muscle cells
[0030] Human primary aortic smooth muscle cell line (HASMC) was selected, and the concentration of ET-1 was 2*10 -8 Mmol / L pretreatment of HASMC caused the abnormal proliferation of HASMC, observed different concentrations of Panax notoginseng saponins (50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600 μg / ml) and control Drug nifedipine (50μg / ml) on it. The results showed that Panax notoginseng saponins could improve the cell viability of ET-1-induced vascular smooth muscle cell proliferation (see figure 1 , figure 2 ).
