| titleOfInvention | Benzofuran compound, and preparation method and application thereof |
| abstract | The invention discloses benzofuran compound, and a preparation method and application thereof. The structural formula of the benzofuran compound is shown in the specification, wherein R is -OH; the molecular formula is C19H16O3; the compound is named gramniphenolF; R is -OMe; the molecular formula is C20H18O3; and the compound is named gramniphenolG. According to the preparation method, dried bamboo orchid branch, leaf and/or fruit are subjected to extractum extracting, organic solvent extracting, silica gelcolumn chromatography and high pressure liquid chromatography separation. The benzofuran compound can be applied to preparation of a drug for resisting tobacco mosaic virus. The inhibition ratios of the gramniphenolF and the gramniphenolG respectively reach 35.8+/-3.6% and 32.1+/-3.8% by an experiment of resistance to tobacco mosaic virus; the benzofuran compound has good activity of resisting the tobacco mosaic virus, and the inhibition ratio is higher than the inhibition ratio (31.8+/-2.5%) of a positive contrast Nanning mycin. The compound disclosed by the invention is simple in structure and good in single activity, can be used as a lead compound of the drug for resisting the tobacco mosaic virus, and has good application prospect. |
