Production of the benzophenanthridine alkaloids in Eschscholtzia californica suspension cell cultures was optimized by adding 0.5 mg methyl jasmonate (MJ) and 0.02 mg salicylic acid (SA)/g FCW after 7 days cultivation. Sanguinarine reached 24 mg/g DCW by such treatment; 10 times higher than in control cell cultures. MJ and SA induced expression of berberine bridge enzyme and 3'-hydroxy-(S)-N-methylcoclaurine-4'-O-methyltransferase, respectively. MJ plus SA induced over-expression of both enzymes.
在花菱草悬浮细胞培养物中，通过在培养7天后添加0.5毫克茉莉酸甲酯（MJ）和0.02毫克水杨酸（SA）/克鲜重细胞，优化了苯并菲啶生物碱的生产。通过这种处理，血根碱达到了24毫克/克干重，比对照细胞培养物中的含量高10倍。MJ和SA分别诱导了小檗碱桥酶和3'-羟基-（S）-N-甲基去甲乌药碱-4'-O-甲基转移酶的表达。MJ加SA诱导了这两种酶的过表达。
