Separation and preparation method of anti-cancer component in lepidium apetalum

The invention discloses a separation and preparation method of anti-cancer components in lepidium apetalum, and relates to the technical field of compound preparation and separation.The separation and preparation method of the anti-cancer components in the lepidium apetalum comprises the following steps that 1, raw materials are prepared; step 2, reflux extraction; step 3, vacuum concentration; step 4, gradient elution; and 5, screening and separating active components, namely separating vanillic acid, syringic acid, ethyl p-hydroxybenzoate and iso-aromatic oxalic acid from the active components. The preparation method has the beneficial effects that anti-cancer components such as vanillic acid, syringic acid, ethyl p-hydroxybenzoate and iso-aromatic oxalic acid in the lepidium apetalum can inhibit the growth of cancer cells, and the purity of the obtained compound is relatively high through separation preparation. 一种钝叶独行菜中抗癌成分的分离及制备方法，涉及化合物制备分离的技术领域，钝叶独行菜中抗癌成分的分离及制备方法包括以下步骤：步骤一、准备原料；步骤二、回流提取；步骤三、减压浓缩；步骤四、梯度洗
