A new naphthaldehyde derivative has been isolated from Comastoma pulmonarium by using various chromatographic techniques, including silica gel, Sephadex LH-20, MCI-gel resin and RP-HPLC. This compounds was determined as 5-methoxy-2-methyl-7-(2-oxopropyl)naphthalene-1-carbaldehyde(1) by NMR, MS, IR and UV spectra. This compound was also evaluated for its anti-tobacco mosaic virus (anti-TMV) activity. The result showed that it showed high anti-TMV activity with inhibition rate of 32.8%. The inhibition rate is close to that of positive control (ningnanmycin).
通过使用各种色谱技术,包括硅胶、葡聚糖凝胶LH-20、MCI凝胶树脂和反相高效液相色谱,从肺草夹竹桃中分离出一种新的萘甲醛衍生物。通过核磁共振、质谱、红外光谱和紫外光谱将该化合物确定为5-甲氧基-2-甲基-7-(2-氧代丙基)萘-1-甲醛(1)。还对该化合物的抗烟草花叶病毒(抗TMV)活性进行了评估。结果表明,它表现出高抗TMV活性,抑制率为32.8%。该抑制率与阳性对照(宁南霉素)相近。
