Acorus tatarinowii Schott extract and its contained chemical compositions could play multiple pharmacological effects in central nervous system,in which the reports on main active parts and chemical compositions( such as volatile oil and β-asarone) from A. tatarinowii improving learning memory and preventing AD are the most in recent years. Based on referring to related literature at home and abroad,different pharmacodynamic actions of A. tatarinowii extract and main chemical compositions on AD and action mechanism are summarized.展开更多
