Abstract

Hypercholesterolemia-induced oxidative stress has been strongly implicated in the pathogenesis of atherosclerosis, which is one of the major causes of mortality worldwide. The current work, for the first time, accounts the antioxidant, genoprotective, antilipoperoxidative, and HMG-CoA reductase (EC 1.1.1.34) inhibitory properties of traditional medicinal plant, Ficus palmata Forsk. Our result showed that among sequentially extracted fractions of Ficus palmata Forsk, FPBA (F. palmata bark aqueous extract) and FPLM (F. palmata leaves methanolic extract) extracts have higher phenolic content and also exhibited significantly more radical scavenging (DPPH and Superoxide) and antioxidant (FRAP) capacity. Moreover, FPBA extract also exhibited significantly higher inhibition of lipid peroxidation assay. Additionally, results showed almost complete and partial protection of oxidatively damaged DNA by these plant extracts when compared to mannitol. Furthermore, our results showed that FPBA extract (IC50 = 9.1 ± 0.61 µg/mL) exhibited noteworthy inhibition of HMG-CoA reductase activity as compared to other extracts, which might suggest its role as cardioprotective agent. In conclusion, results showed that FPBA extract not only possess significant antioxidant and genoprotective property but also is able to attenuate the enzymatic activity of HMG-CoA reductase, which might suggest its role in combating various oxidative stress-related diseases, including atherosclerosis.

摘要

高胆固醇血症诱导的氧化应激与动脉粥样硬化的发病机制密切相关,动脉粥样硬化是全球主要的死亡原因之一。目前的研究首次阐述了传统药用植物无花果(Ficus palmata Forsk)的抗氧化、基因保护、抗脂质过氧化和HMG-CoA还原酶(EC 1.1.1.34)抑制特性。我们的结果表明,在无花果依次提取的各组分中,FPBA(无花果树皮水提取物)和FPLM(无花果叶甲醇提取物)提取物具有较高的酚类含量,并且还表现出显著更强的自由基清除(DPPH和超氧化物)和抗氧化(FRAP)能力。此外,FPBA提取物在脂质过氧化试验中也表现出显著更高的抑制作用。此外,与甘露醇相比,这些植物提取物对氧化损伤的DNA显示出几乎完全和部分的保护作用。此外,我们的结果表明,与其他提取物相比,FPBA提取物(IC50 = 9.1 ± 0.61 µg/mL)对HMG-CoA还原酶活性表现出显著的抑制作用,这可能表明其作为心脏保护剂的作用。总之,结果表明FPBA提取物不仅具有显著的抗氧化和基因保护特性,而且能够减弱HMG-CoA还原酶的酶活性,这可能表明其在对抗包括动脉粥样硬化在内的各种氧化应激相关疾病中的作用。
