The aqueous and ethanolic extracts of Lippia sidoides Cham. were chemically characterized and tested for their action on enzymes involved in processes such as inflammation, blood coagulation, and digestion. Both extracts potentiated the activity of phospholipases A present in the venom of Bothrops atrox in 12 % and completely inhibited the hemolysis induced by B. jararacussu and B. moojeni venoms in the proportions between 1 : 0.5 and 1 : 5 (venom/extracts (w/w)). They inhibited the thrombolysis induced by B. moojeni (10 to 25 %), potentiated the thrombolysis induced by the Lachesis muta muta venom (30 to 80 %), prolonged the coagulation time induced by B. moojeni and L. muta muta venoms, and presented antigenotoxic action. Both extracts reduced the activity of α-glycosidases, the aqueous extract inhibited lipases, and the ethanolic extract inhibited α-amylases. The results demonstrate the modulatory action of the extracts on proteases, phospholipases, and digestive enzymes. In addition, the rich phenolic composition of these extracts highlights their potential for nutraceutical use.
对南美牛至(Lippia sidoides Cham.)的水提取物和乙醇提取物进行了化学表征,并测试了它们对参与炎症、血液凝固和消化等过程的酶的作用。两种提取物均使矛头蝮蛇毒中磷脂酶A的活性增强了12%,并以1∶0.5至1∶5(毒液/提取物(重量/重量))的比例完全抑制了由巴西矛头蝮蛇毒和莫氏矛头蝮蛇毒诱导的溶血。它们抑制了莫氏矛头蝮蛇毒诱导的血栓溶解(10%至25%),增强了巨蝮蛇毒诱导的血栓溶解(30%至80%),延长了莫氏矛头蝮蛇毒和巨蝮蛇毒诱导的凝血时间,并表现出抗基因毒性作用。两种提取物均降低了α-糖苷酶的活性,水提取物抑制脂肪酶,乙醇提取物抑制α-淀粉酶。结果证明了提取物对蛋白酶、磷脂酶和消化酶的调节作用。此外,这些提取物丰富的酚类成分突出了它们在营养保健品方面的应用潜力。
