(1) The discrimination of Marchantia polymorpha , Marchantia convoluta and succeeded by Ultraviolet Absorption Spectra Lines Group ( UASLG ).

(2) These methods were used to determine flavonoids in Marchantia convolute with satisfactory results.

(3) Determination of the Content of Flavonoids in Marchantia convolute L.

(4) A method for determination of apigenin in Marchantia polymorpha was established.

(5) Objective: To study the role of chitosan elicitor on cell growth and phenolic compound contents of Marchantia polymorpha L.

(6) To induce callus tissues and establish suspension culture of Marchantia polymorpha L.

(7) Conclusion: The ability to de-oxidation decreases and an oxidation increase of Marchantia polymorpha cells induced by chitosan may favor the phenolic compounds biosynthesis.
