摘  要:
以烟草花叶病毒(TMV)为供试病毒,采用半叶枯斑法测定了白术提取物对TMV的生物活性。结果表明:在供试浓度为10 g/L时,白术石油醚提取物对TMV具有明显的体外钝化作用,钝化0.5 h后,其抑制率达61.86%;对TMV的初侵染和增殖也有一定的抑制作用,处理24 h后,抑制率分别为40.12%和20.03%。白术中抗病毒的活性成分主要存在于石油醚萃取物中。

摘  要:
The antiviral activity of extract from Atractylodes macrocephala on tobacco mosaic virus (TMV)was determined by a half-leaf necrosis method.The results showed that at 10 g/L the petroleum ether extract of A.macrocephala had an obvious external passivation on TMV,and after 0.5 h passivation the inhibition percentage was 61.86%.The petroleum ether extract also had a certain inhibiting effect on primary TMV infection and proliferation,and after 24 h treatment the inhibition percentage was 40.12%and 20.03%,respectively.
