Abstract:The discrimination of Marchantia polymorpha , Marchantia convoluta and Marchantia paleacea was succeeded by Ul-
traviolet Absorption Spectra Lines Group(UASLG).The UV spectra of the solutions extracted by four different kinds of solvents
(water , chloroform , ethanol and petroleum ).The UV spectra of the three herbals gave different maximum absorption peaks
both in number and intensities.The method was simple and accurate and can be used to distinguish one from others.

Marchantia polymorpha is a Traditional Chinese Medicine
herb.There are a large number of Marchantineae plants
in Guangxi such as Marchantia polymorpha , Marchantia
convoluta and Marchantia paleacea.These species live in
together.It is difficult to distinguish one from others.Ul-
traviolet Absorption Spectra Lines Group (UASLG)is a
efficient method for identification of medicine herb.It is
simple and accurate to use UASLG to identify Chinese
Traditional Medicine herbs[ 1-3] .
Experimental
Instrumentation and reagent
A UV-756 spectrophotometer from Shanghai China Ana-
lytical Instrument General Factory was used to record the
ultraviolet spectra.Chloroform 、ethanol and petroleum
(bp.60 ~ 90 ℃)were of analytical-reagent grade.
The water used was distilled for one time.
Material
The material of Marchantia polymorpha , Marchantia con-
voluta and Marchantia paleacea were afforded by Guangxi
Chinese Medical University and were identified by Profes-
sor Zhou Zi-jing in Guangxi Chinese Medical University.
Methods
Ultraviolet Absorption Spectra Lines Group was used.
Dried power(2.00 g , four segment )of M.polymorpha ,
M.convoluta and M.paleacea were extracted with wa-
ter , ethanol , chloroform and petroleum for two hours at
room temperature.Every solution is 20 mL.These solu-
tion were filtrated , then were put in quart utensil and
scanned in spectrophotometer using corresponding solvents
as blank solution.If the absorbency is too high , the solu-
tions need to be diluted.Scanning wavelength is from 190
nm to 400 nm.The rate of scanning is 200 nm/min.Ab-
sorbency is between 0 to 3.000.
Results
The maximum absorption peaks′number and intensities of
these three plants , as shown in table 1.
The results indicated that the UV spectra of M.polymor-
pha , M.convoluta and M.paleacea gave different maxi-
mum absorption peaks.This method can be used to dis-
tinguish one from others.

Discussion
M.polymorpha ,M.convoluta and M.paleacea belong to
family Liverworts and genus Marchantia L.It s difficult
to identify them by traditional methods.But this problem
can be solved through Ultraviolet Absorption Spectra Lines
Group (UASLG).The UV spectra of these plants gave
different maximum absorption peaks in different solvents
both in number and intensities.
Ultraviolet Absorption Spectra Lines Group(UASLG)us-
ing several solvents not only can distinguish the Chinese
traditional medicine from their counterfeits , but also can
be used to identify herbal drugs with the same genus.
The UV spectra of the three plants gave different maxi-
mum absorption peaks both in number and intensities.
From UV spectra of the three herbal drugs , we can con-
clude that the chemical constituents of the three herbal
drugs had many different , too.M.convolute is a main
specie of Marshantia plant in Guangxi.There are few re-
ports about constituents of M.convoluta living in China ,
to our knowledge , been performed.We will continue to
report the chemical constituents of the three herbal drugs.
