羟基红花黄色素A对实验性脑缺血的保护作用 总被引:22,自引:0,他引:22
红花为菊科植物红花(Carthamus tinctoriusL.)的干燥花,是传统的活血化瘀类代表药物[1]。红花的化学成分比较复杂,研究表明,红花的花中含有黄酮类、脂肪酸、色素、挥发油以及多炔等化合物[2]。目前认为,红花活血化瘀的主要成分集中在水溶性的黄色素部分;红花黄色素主要成分有羟基红花黄色素A(hydroxysafflor yellow A,HSYA)、红花明苷A、红花明苷B及其他含量较低的成分。在红花黄色素中含量最高且具有活性的成分为羟基红花黄色素A[2]。作者采用经典的大鼠大脑中动脉阻塞性脑缺血模型,观察HSYA对局灶性脑缺血大鼠的行为评分、缺血区面… 相似文献

Safflower, the dry flower of Carthamus tinctorius L., has long been applied for empirically treating cerebral ischemia and depression in traditional Chinese medicine. Pathogenesis of major depression involves monoaminergic transmission. The present study assessed whether safflower or its isolate would be effective in functionally regulating monoamine transporter using in vitro screening cell lines. We discovered that safflower insoluble fraction significantly inhibited serotonin uptake in Chinese hamster ovary cells stably expressing serotonin transporter (i.e. S6 cells). This fraction went through an activity-guided isolation and an active ingredient was obtained, which was subsequently elucidated as a novel coumaroylspermidine analog N1,N5-(Z)-N10-(E)-tri-p-coumaroylspermidine using NMR techniques. Pharmacologically, this compound potently and selectively inhibited serotonin uptake in S6 cells or in synaptosomes, with IC50 of 0.74 ± 0.15 µM for S6 cells or 1.07 ± 0.23 µM for synaptosomes and with a reversible competitive property for the 5HT-uptake inhibition. The potency of it for 5HT uptake was weaker than that of fluoxetine whereas efficacy generally similar for both. Animals treated with this testing compound showed a significant decrease in synaptosomal 5HT uptake capacity. Thus, N1,N5-(Z)-N10-(E)-tri-p-coumaroylspermidine is a novel serotonin transporter inhibitor, which could improve neuropsychological disorders through regulating serotoninergic transmission. 相似文献

The analgesic properties of the “CF” oil preparation extracted from safflower (Carthamus tinctorius L.) seeds were studied. The local anesthetic lidocaine and the tricyclic antidepressant amitriptyline, which induce complete
block of the sciatic nerve, were used as positive controls. The actions of CF were associated with significant decreases in
the nociceptive and proprioceptive functions of the sciatic nerve in mice. At a dose of 0.1 ml, this agent was sufficient
to produce partial local anesthesia of the hindlimb, innervated by the sciatic nerve, without producing any toxic side effects.
Thus, CF is a natural local anesthetic with moderate analgesic activity mediated by influences on the serotoninergic and monoaminergic
pathways. CF may occupy a leading place among local anesthetics used in traditional medicine, particularly in pharmacotherapy
and acupuncture, as well as medical massage.

红花黄素对高血压大鼠的降压作用及对肾素-血管紧张素的影响 总被引:31,自引:0,他引:31
Safflower yellow (SY) is a mixture of chalconoid compounds extracted from Carthamus tinctorius L. Ig SY 1~2 g·kg-1·d-1lowered the blood pressure of spontaneously hypertensiverats (SHR), for about 1.86~3.86 kPa. Five weeks after administration of SY, the plasma renin ac-tivity and angiotensin Ⅱ level diminished in the SHR experimental groups. These suggest that the de-crease of blood pressure is mediated by the renin-angiotensin system. 相似文献
