The contents of mineral elements, like Fe, in LMTCMs were higher than that of nor-LMTCM. The result of analysis of mineral element of 14 LMTCMs by ICP-MS method also showed the content of Fe have something to do with lung meridian tropism effects. The result of the study of platycodon radix approved the laws too. These laws were used to predict if the marine medicines have the lung meridian tropism effects.2. The Compatibility laws of Medicines and their chemical composition in LSP were studied by mining the data of the constituent herbs and their chemical composition. The results showed that the most constituent medicines of lung system prescriptions have lung meridian tropism. Radix glycyrrhizae, herba ephedrae, semen armeniacae amarum, fructus schisandrae Chinese and their compatibility are common in lung system prescriptions. Terpene, alkaloid, steroid, and flavanoid compounds and their compatibility are common in lung system prescriptions.3. The marine phycophyta medicines of LSP were studied by the same method.
对比归肺经中药及肺系方剂主要化学成分构成,萜类、生物碱、甾体类成分可能是归肺经中药及肺系方剂的主要药效成分;结合君臣佐使药的化学成分构成特点及肺系方剂组成中药的归经构成情况,肺系方剂组方设计应该考虑以下几个方面:一、优先考虑归肺经中药,在应用不归肺经中药时要配伍归肺经中药;二、组方时应考虑含萜类、甾体及生物碱类化合物的中药;治疗肺咳病及咳嗽症状时可以考虑含萜类化合物的中药,治疗气喘症状时可以考虑含生物碱类化合物的中药;三、在确定组方中药或化学成分配伍关系时,君药多考虑含生物碱、黄酮类化合物的中药;臣药、佐药可以考虑含萜类及甾体类化合物中药;使药可以考虑含萜类、甾体类及黄酮类化合物的中药。
