青蒿素(QHS)系青蒿(菊科植物黄花蒿Artemisiaannua L.)的强抗疟成分。由于目前黄花蒿只在中国生长丰富,而合成青蒿素代价昂贵。故作者试图运用组织培养技术以较低的代价大量获得青蒿素。含量测定:新鲜植物根、愈伤组织、胚、芽,在组织研磨机中用MeCN 提取,提取液浓缩至原体积1/25,过滤备用。培养液用己烷提取,除去己烷,残渣加MeCN Artemisinin (QHS) is a strong antimalarial component of Artemisia annua (Compositae Artemisia annua L.). Because Artemisia annua currently only grows abundantly in China, it is expensive to synthesize Artemisinin. Therefore, the author tried to use tissue culture technology to obtain artemisinin at a low cost. Content determination: Fresh plant roots, callus, embryos and buds were extracted with MeCN in a tissue mill. The extract was concentrated to a volume of 1/25 and filtered for use. The broth was extracted with hexane, hexane was removed, and the residue was added with MeCN
