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 vanillin-glacial acetic acid method, ultraviolet spectrophotometry (UV) is detected at 548nm, and the percentage by weight of the total saponins of Panax 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 duodenal administration);
[0018] SHR rats were divided into blank group (0.9% NS duodenal administration);
[0019] Panax notoginseng total saponins low-dose group (0.8g / kg of Panax notoginseng total saponins administered in the duodenum);
[0020] Middle dose group of total saponins of Panax notoginseng flower buds (1.6g / kg total saponins of Panax notoginseng flower buds administered in duodenum);
[0021] Panax notoginseng total saponins high-dose group (3.2 g / kg total saponins from Panax notoginseng flower buds administered in the duodenum);
[0022] Nifedin group (nifedin 5mg / kg duodenal administration).
[0023] 3. Acute antihypertensive test:
[0024] Each group was anestheti...
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 HASMC was pretreated with ET-1 concentration of 2*10-8mmol / L, which caused the abnormal proliferation of HASMC. 200, 250, 300, 350, 400, 450, 500, 550, 600 μg / ml) and the control drug nifedipine (50 μg / ml). The results show that Panax notoginseng saponins can improve the cell viability of ET-1-induced vascular smooth muscle cell proliferation (see figure 1 , figure 2) .
