摘要：分别采用冷提法(CE)和热提法(HE),以水和乙醇为溶剂制备奇楠(QN)、传统沉香(TA)提取物,通过GC-MS和HPLC法对提取物的化学成分进行分析,并探讨了其抗氧化活性和抑菌活性。研究结果表明:QN中倍半萜类化合物的种类少于TA,但是两者共有的倍半萜类化合物含量QN高于TA。QN中基本不含四氢-2-(2-苯乙基)色酮(THPECs),主要含有Flidersia型2-(2-苯乙基)色酮(FTPECs),其中2-(2-苯乙基)色酮质量分数可达10.87%,2-[2-(4-甲氧基苯)乙基]色酮质量分数为4.80%。TA中THPECs种类和含量丰富,沉香四醇质量分数可达1.50%。QN与TA提取物对ABTS自由基清除能力和铁离子还原能力均随乙醇体积分数(0~55%)提高而增加,QN水提取物的抗氧化活性低于TA,但乙醇提取物抗氧化活性优于TA。QN和TA提取物对大肠杆菌无显著的抑菌活性,两者水提取物对白色念珠菌均具有抑菌活性。
The extracts of Qinan(QN)and traditional agarwood(TA)were prepared by cold extraction(CE)and hot extraction(HE)with water and ethanol as solvent,respectively.The chemical constituents of the extracts were analyzed by GC-MS and HPLC,and their antioxidant and antibacterial activities were studied.The results showed that the species of sesquiterpenoids in QN were less than those of TA,while the contents of sesquiterpenoids in both were higher than that of TA.There was almost no tetrahydro-2-(2-phenylethyl)chromones(THPECs)in QN,and Flidersia type 2-(2-phenylethyl)chromones(FTPECs)was contained,where the mass fraction of 2-(2-phenethyl)chromone could reach 10.87%,and the mass fraction of 2-[2-(4-methoxy)phenethyl]chromone was 4.80%.The species and contents of THPECs in TA were rich,and the mass fraction of agartetrol could reach 1.50%.With the increasing ethanol volume fraction(0-55%),the ABTS free radical scavenging ability and iron ion reduction ability of QN and TA extracts increased.Although the antioxidant activity of QN water extracts was lower than that of TA,while its ethanol extracts were higher than that of TA.QN and TA had no significant antibacterial activity against Escherichia coli,but their water extracts had antibacterial activity against Candida albicans.
