制备

1.取地不容根粉1kg，用0.6L 5% Na2CO3溶液润湿后放置2h，晾干，使植物组织充分吸收碱液。然后用苯1.5L浸泡3天后过滤，残渣用苯再泡2天，过滤后再用同量的苯浸泡一次，收集合并3次苯液，用10%盐酸萃取，在酸萃取过程中有大量白色粥样物析出，极易乳化。苯液用酸萃取至不含生物碱为止，萃取的酸液用饱和Na2CO3液碱化，碱化液再用氯仿萃取4次，合并氯仿萃取液，用无水硫酸钠干燥。蒸馏回收氯仿，得淡黄色泡沫状总生物碱，重17.5g左右。再将总碱溶于35ml丙酮中，放置2h，可析出白色针状结晶，过滤，用少量丙酮洗1次，干燥后得轮环藤碱1.8g。

取上述丙酮母液加苯2.5ml，放置过夜，析出柱状结晶，过滤，再用丙酮洗一次，干燥后得千金藤素苯加成物6.8g。再将其溶于氯仿，通过氧化铝层析柱(1g生物碱用3g氧化铝)，浓缩，所得沉淀过滤和干燥后得淡黄色泡沫状无定形粉末，即为千金藤素。
