The invention discloses an extraction method of natural p-hydroxybenzaldehyde. According to the extraction method, natural p-hydroxybenzaldehyde is extracted by taking triarrhena lutarioriparia as anextraction object, and the extraction object is preferably triarrhena lutarioriparia tender stems, especially shelled triarrhena lutarioriparia tender stems or waste bamboo shoot shells of triarrhenalutarioriparia tender stems or waste bamboo shoot heads of triarrhena lutarioriparia tender stems. According to the method, triarrhena lutarioriparia is selected as an extraction object for the firsttime in the field. The method is sufficient in raw material source, simple and convenient in process, low in cost, high in product purity, few in impurity, environmentally friendly, capable of achieving large-scale production, high in commercial value and wide in application prospect. 本发明公开了一种天然对羟基苯甲醛的提取方法，该提取方法是以南荻作为提取对象来提取天然对羟基苯甲醛，提取对象优选南荻嫩茎，尤其是去壳的南荻嫩茎或南荻嫩茎的废弃笋壳或南荻嫩茎的废弃笋头。本发明的方法选用南荻作为提取对象为本领域首创，该方法原料来源充足，工艺简便，成本低廉，产品纯度高、杂
