| titleOfInvention | A kind of enantiopimarane type diterpene and its preparation method and application |
| abstract | The invention discloses an enantiopimarane type diterpene and a preparation method and application thereof. In the present invention, after drying and pulverizing the root of spurge of Hubei, it is first extracted with methanol, then extracted with ethyl acetate and n-butanol respectively, and finally the ethyl acetate part is used in a macroporous resin column, a silica gel column, a reversed-phase chromatographic column and a The compound was isolated by semi-preparative reverse-phase high performance liquid chromatography. The compound has obvious phytotoxic activity on the roots and leaf sheaths of bluegrass seedlings, and it is found through experiments that its inhibitory rate on bluegrass is higher than that of the positive control glyphosate, but it has no obvious inhibition on the roots and leaf sheaths of lettuce Therefore, the compound can be used as a selective herbicide in vegetable fields. The enantiopimarane-type diterpene is a yellow oil, and its chemical structural formula is shown in formula (I): |
