药理研究表明,防风提取物可抑制佐剂性关节炎、消化性溃疡,并具有抑制中枢神经系统、止痛、抗惊厥和抗炎活性。化学研究分离出色酮、香豆素及聚乙炔成分,但各种化学成分的药理活性并不明确。本次用活性定向分离法确定防风的止 Pharmacological studies have shown that the anti-wind extract can inhibit adjuvant arthritis, peptic ulcer, and inhibit the central nervous system, analgesia, anticonvulsant and anti-inflammatory activity. Chemical studies have isolated excellent ketones, coumarins, and polyacetylenes, but the pharmacological activities of various chemical components are not clear. This time, we determined the wind resistance by active orientation separation method.
