厚朴药材具有止咳祛痰作用，对气管平滑肌具有收缩和舒张的双向作用。厚朴酚及和厚朴酚是疏水性烯丙基联苯酚类结构的同分异构体，也是厚朴产生呼吸系统药理作用的主要活性成分。厚朴酚及和厚朴酚都具有松弛气管平滑肌作用和平喘作用，都具有肺保护作用和对抗各种病理因子引起的肺损伤作用。厚朴酚及和厚朴酚还具有广谱的抗病毒、抗菌和细胞保护作用，尤其适用于具有基础疾病的各种肺损伤，以期被开发为新药供临床利用。

Research advances on pharmacologic effects in respiratory system of extract, magnolol and honokiol from Magnoliae Officinalis Cortex

Magnoliae Officinalis Cortex has antitussive and expectorant effects, and dual-directional action on contraction and relaxation of bronchial smooth muscle. Magnolol and honokiol are hydrophotic isomer of propenyl biphenol-type structure, and major active components of Magnoliae Officinalis Cortex in pharmacologic action of respiratory system. Magnolol and honokiol have relaxation of trachea smooth muscle and antiasthmatic effect, have lung-protection, and antagonize lung injury induced by various pathological factors. Magnolol and honokiol have broad-spectrum antibacterial and anti-viral effects, and cellular protection, too. Magnolol and honokiol to prevention and treatment for various pneumonia with basic disease were recommended, intended to be developed as a new drug for clinical use.
