The aim of the present study was to develop the HPTLC fingerprint and to evaluate the in-vitro antioxidant, anti-inflammatory and anti-diabetic activities of ethanol extract of leaves of Actinodaphne madraspatana Bedd (A. madraspatana). HPTLC fingerprint analysis of ethanol extract was investigated by win CATS planar chromatography. The antioxidant activity was evaluated by the various antioxidant assays, such as total antioxidant, reducing power, DPPH radical scavenging, hydrogen peroxide scavenging and hydroxyl radical scavenging. The antioxidant activity was compared to standard drug ascorbic acid. In-vitro anti-inflammatory activity was evaluated by inhibition of albumin denaturation assay using aspirin as a standard drug. In-vitro anti-diabetic activity was evaluated by α-amylase inhibition assay using acarbose as a standard drug. The HPTLC fingerprint of ethanol extract has shown six peaks, which indicate the presence of six different phytocomponents. The in-vitro antioxidant, anti-inflammatory and anti-diabetic activities of ethanol extract of plant leaves increased with the increasing of concentration. The result revealed that extract in all the concentration showed the in-vitro antioxidant, anti-inflammatory and anti-diabetic activities compared to standard drugs. The ethanol extract of leaves of A. madraspatana has a potential effect as an antioxidant, anti-inflammatory and anti-diabetic in all the tested in-vitro methods.
本研究的目的是建立马德拉斯樟(Actinodaphne madraspatana Bedd,简称A. madraspatana)叶片乙醇提取物的高效薄层色谱(HPTLC)指纹图谱,并评估其体外抗氧化、抗炎和抗糖尿病活性。采用win CATS平面色谱法对乙醇提取物进行HPTLC指纹图谱分析。通过多种抗氧化试验评估抗氧化活性,如总抗氧化能力、还原力、1,1-二苯基-2-三硝基苯肼(DPPH)自由基清除能力、过氧化氢清除能力和羟自由基清除能力。将抗氧化活性与标准药物抗坏血酸进行比较。以阿司匹林为标准药物,通过抑制白蛋白变性试验评估体外抗炎活性。以阿卡波糖为标准药物,通过α-淀粉酶抑制试验评估体外抗糖尿病活性。乙醇提取物的HPTLC指纹图谱显示出六个峰,表明存在六种不同的植物成分。植物叶片乙醇提取物的体外抗氧化、抗炎和抗糖尿病活性随浓度增加而增强。结果表明,与标准药物相比,所有浓度的提取物均表现出体外抗氧化、抗炎和抗糖尿病活性。在所有测试的体外方法中,A. madraspatana叶片的乙醇提取物具有作为抗氧化剂、抗炎剂和抗糖尿病药物的潜在作用。
