将人参(Panax ginseng)用适当的有机溶剂提取,提取物的水溶性部分用弱酸性离子交换树脂处理,把吸附在树脂上的成分用稀酸溶离浓缩,就可得到人参的降压成分。目的是为了制出新的有效的降压剂。发明者等通过药理实验证明,人参确实含有效的降压成分。经过努力成功地制成了降压效果非常高的浓缩物。 Ginseng (Panax ginseng) is extracted with a suitable organic solvent. The water-soluble portion of the extract is treated with a weakly acidic ion exchange resin, and the components adsorbed on the resin are dissolved with a dilute acid to concentrate the pressure-reducing component of the ginseng. The purpose is to make new effective hypotensive agents. The inventors have proved through pharmacological experiments that ginseng does contain effective antihypertensive ingredients. After hard work, we successfully made a concentrate with very high pressure reducing effect.
