    摘要： Provided is a method for preparing a taxane derivative, comprising: carrying out condensation of a phenylisoserine derivatives having a protective group introduced thereto or a mixture of isomers thereof, as a side chain, with a baccatin III derivative or 10-deacetyl-baccatin III derivative to obtain a mixture of isomers; separating the isomers via chromatography; and carrying out a reversion of the stereochemical structure of a selectively separated isomer, which is suitable for producing a taxane derivative in a large scale with high yield.

    摘要： This invention relates to methods for purification of paclitaxel from a paclitaxel-containing material. The method comprises the following steps: (a) extracting a paclitaxel-containing material with an organic solvent to obtain an extract, and concentrating the extract; (b) adding the concentrate with an organic solvent which is not mixed with water to separate an organic solvent phase and then concentrating; (c) subjecting the concentrate to normal phase chromatography to obtain an eluate; (d) dissolving the eluate in an acetone or dichloromethane followed by adding pentane or hexane to form a precipitate; and (e) subjecting the precipitate to high performance liquid chromatography. According to the method of the present invention, paclitaxel of over 99.5% purity can be easily obtained from a Taxus genus plant with a high yield.

    摘要： The present invention relates to a liquid crystal display including: a first substrate and an opposing second substrate; a liquid crystal layer interposed between the first substrate and the second substrate; a light blocking member disposed on the first substrate or the second substrate; a first field generating electrode disposed on the first substrate; a second field generating electrode disposed on the first substrate and including branch electrodes overlapping the first field generating electrode; and a gate line disposed on the first substrate and extending in a first direction. A branch electrode of the branch electrodes includes a central portion and a first edge portion disposed at one end of the central portion. A first angle formed between the first edge portion and a second direction is greater than a second angle formed between the second direction and the central portion, the second direction being perpendicular to the first direction.
