从山扁豆(Cassia leschenaultiana)中分离出两种新化合物(1和2)以及三种已知的色酮衍生物(3 - 5)。通过光谱方法,包括大量的一维和二维核磁共振技术确定了它们的结构。对化合物1和2进行了抗烟草花叶病毒(anti - TMV)活性评估。结果表明,在浓度为20μM时,化合物1和2显示出潜在的抗TMV活性,抑制率分别为35.6%和38.7%。这些比率高于阳性对照的比率。
Two new compounds (1 and 2), together with three known chromone derivatives (3–5), were isolated.from Cassia leschenaultiana. Their structures were elucidated by spectroscopic methods, including extensive.1D and 2D NMR techniques. Compounds 1 and 2 were evaluated for their anti-tobacco mosaic virus.(anti-TMV) activity. The results showed that compounds 1 and 2 showed potential anti-TMV activities with.inhibition rates of 35.6% and 38.7% at the concentration of 20 μ M, respectively. These rates are higher than.that of the positive control.
