[ Method ] MS culture medium was used to bourgeon seedlings of cassia seed and to induce cotyledon callus of cassia seed while HPLC method was adopted to determine emodin and ehrysophanol eontents.[ Result] Emedin and chrysophanol contents in cotyledon callus were 0. 099% and 0. 312%, respectively, while they were 0.029% and 0. 190% respectively in cassia seed. [ Conclusion] The method of inducing cotyledon callus was helpful for increasing emodin coment in cassia seed.展开更多
