Industrial hemp full-spectrum oil extraction method

The invention relates to a method for extracting industrial hemp full-spectrum oil, which comprises the following steps of: decarboxylating industrial hemp by using microwave drying equipment, extracting by using supercritical carbon dioxide to obtain extract, winterizing and dewaxing the extract, and separating by using preparative chromatography to obtain the industrial hemp full-spectrum oil. According to the industrial hemp full-spectrum oil prepared by the method disclosed by the invention, chlorophyll does not need to be removed through a color removal step, the obtained industrial hemp full-spectrum oil is high in CBD yield and high in CBD content, and the industrial hemp full-spectrum oil contains THC with the mass percent being 0.1% or below. 本发明涉及一种工业大麻全谱油提取方法，将工业大麻用微波干燥设备脱羧，再用超临界二氧化碳萃取得到浸膏，浸膏经过冬化脱蜡步骤，用制备色谱分离得到工业大麻全谱油。按照本发明公开的方法制备得到的工业大麻全谱油，无需通过除色步骤去除叶绿素，得到的工业大麻全谱油CBD收率高，CBD含量高，且具有质量百分比为0.1％以下的THC。
