To summarize the research progress on chemical components and pharmacological actions of Clerodendron trichotomum and provide useful references for the further research.All papers about chemical components and pharmacological actions in CNKI

MEDLINE and CA databases etc were referred to and summarized. The chemical components isolated from C. trichotomum. include mainly essential oil

flavone

phenylpropanoids

glucoside and alkaloids; Pharmacological references show that it has depressurization

anti-inflammation

anti-oxidation

analgesia

mitigate

anti-cell multiplication and anti-HIV. The studies about big heteropolarity components which related with chemical and pharmacological have been reported more

however

the moderate and small heteropolarity components were researched lessly

we should carry out further studies on moderate and small heteropolarity components

to establish foundation for C. trichotomum’quality criteria and deep development.
