    S op hora f lavescens Ait . is an indig enous
perennial herb in China. It is dist ributed thr ough-
out the mainland China, ranging fr om low to high
lat itudes. T he r oots, as a typical t radit ional Chi-
nese herb, are mainly used in the t reatment of
fever, pept ic ulcer , eczema, hemorrhoids, asth-
ma, tumors, bacillar y dysentery and as analo-
gy
[ 1, 2] . T he her b is known to contain mo re than
ten kind of quino lizidine alkalo ids
[ 3]
, among which
oxymatrine is one of the majo r bio act ive compo-
nents
[ 4]
. Due to it s highly pharmacolo gical act ivi-
ties, such as ant ipy retic, ant iulcer , nonsteroidal
ant i-inf lammato ry and antitumor [ 5- 10] , it has been
studied g reat ly and deveolped into several patent
medicines and some kind of medicinal herb pest i-
cides in the past ten year s[ 11- 14] . At pr esent , com-
plete chemical synthesis o f ox ymatrine has no t
been r eported and its commercial supply st ill de-
pends on the isolat ion fr om the roo ts of natur al
sources. In r ecent y ears, uncontrolled cont inuous
co llect ion of plant material f rom natural habitat for
the ex t ract ion o f alkalo ids has led to the sharp de-
plet ion of w ild S. f lavescens population. It is es-
sent ial to develop the large-scale cult ivat ion of this
plant . How ever , a few studies has been conducted
to evaluate the effect of producing area and plant
age on oxymatrine lev els in the root of S.
f lavescens gr ow ing in dif ferent pro vinces in China,
and to est imate the total root biomass and oxyma-
tr ine content . In this paper , variat ion in the oxy-
matrine content of the roo ts fr om dif ferent areas
and dif ferent ag es g row ing in a homogenous envi-
ronment has been determ ined.
1 Materials and methods
1. 1 Chemical agents
T he standard oxymatrine w as purchased from
Sigma Chem. Co. ( USA ) . Sodium dihydro-pho s-
phate, phosphor ic acid, methanol, and sodium
perchlorate w ere all HPLC g rade. Water w as dou-
ble-dist illed.
1. 2 Plant material and r oot collect ion
T he roo t samples w er e bought f rom medicinal
markets within differ ent pr ovinces in October,
2001, w hich were collected f rom dif ferent reg ions
in September in the ident ical y ear and air dried.
T he air dried root samples w ere dried in an oven at
70℃ up to constant w eight , then w er e f inely pow-
dered in a blender .
1. 3 Determ inat ion of ox ymatr ine
Determination of ox ymatrine in the roo t sam-
ple w as carried out by the method of quant ification
against ex ter nal standard[ 15] .
1. 4 So lut ion preparat ion of authentic oxymatr ine
Standard oxymatr ine ( 5 mg ) w as w eighed ac-
curately and put into vo lumetric f lask of 50 mL,
and then dissolved and identif ied the volume w ith
mobile phase used in HPLC analysis.
1. 5 So lut ion preparat ion of sample oxymatrine
Powder o f dried roo t sample ( 500 mg ) w as
w eighed accurately and put into volumetric f lask of
50 mL and 30 mL mobile phase w as added, then
the volumetric flask w as vibrated in an ul tr asonic
g enerator for 30 m in, laid aside unt il the tempera-
ture of the solut ion was down to room tempera-
·449·中草药 Chinese T raditional and Herbal D rug s 第 35 卷第 4 期 2004年 4月
ture. T o f ilter the so lut ion using 0. 45 Lm filter
membrane after fix ing the volume with mobile
phase used in HPLC analysis, the f ilt rate w as used
as the solut ion o f ox ymatrine sample fo r HPLC
analy sis.
1. 6 HPLC analysis
Quant ificat ion of ox ymatrine content in the
roo t sample w as carried out by subject ing solut ion
of ox ymatrine samples ( 10 LL) to HPLC analy sis
equipped w ith a r everse phase column [ Zo rbax SB-
C18, 150 mm×4. 6 mm, 5 Lm) , Ag ilent , USA ] .
The sample w as eluted in an iso crat ic mode w ith
NaH2PO 4-H3PO4-NaClO4-MeOH-H2O ( 3. 3 g ∶
0. 85 mL∶10 g∶75 mL∶425 mL ) at a f low rate
of 1. 0 mL/ min and the column elute w as moni-
to red at 220 nm w ith a UV deterctor ( Waters 600
photodiode arr ay detector, Millipore, U SA ) and
Waters printer plo tter ( M illipore, Waters) . Oxy-
matrine content w as quant ified on the basis of
standard curve pr epared by inject ing known quant i-
ties of authentic oxymatrine.
1. 7 Plant ag e and calculation of roo t biomass
The plant ag e w as calculated on the basis of
seeding and the ro ot biomass w as obtained by
w eighing the intact root w hich w as dried in an oven
at 70℃ up to constant w eight af ter being collected
fr om the soil ver y carefully .
1. 8 Statistical t reatments
The various stat ist ical t reatments w ere carr ied
out following M icrosof t Excel pr ogramme and
SPSS 9. 0 for Window s.
2 Results and discussion
Signif icant variat ion in the oxymatrine content
w as found in the r oot samples w ithin the natur al
populat ion of S. f lavescens g row ing in dif ferent
pr ovinces in China ( Table 1 and 2) . Based on
ANOVA ( Analy sis of variance) , a highly signif i-
cant dif ference at 0. 01 level can be observed in
oxymatrine content of roo t col lected f rom dif ferent
pr ovinces. The values range f rom 0. 494% to
4. 127% ( coef f icien of variat ion= 53. 96% ) and the
max imum ( avg . 3. 493% ) oxymatrine lev el w as
recor ded in the roo t f rom Heilong jiang prov ince.
Further , considerable differ ences w ere also ob-
ser ved in oxymatrine content in the ro ot samples
f rom different geog raphical locations in the ident i-
cal province. T hese dif ferences may indicate the ef-
fect of g enet ic and epigenet ic variation on oxyma-
trine content in the roo t of S. f lavescens, although
l it t le or nothing w as known about it . Further-
more, the r esult suggests that there be opportuni-
t ies to select superior areas for high-yielding plant
cultivat ion by applying st rong select ion pressure.

  More interestingly , this study also indicates
that the samples f rom the cold ar id nor thern high-
lat itude areas had higher o xymatrine concentr ation
than those f rom w arm humid southern low-lat itude
parts of the mainland China. T o invest igate the ef-
fect o f environmental variat ion on oxymatrine con-
tent in the roots of S. f lavescens, the roo t samples
f rom 14 provinces ( Their ex act geog raphical loca-
t ions are show n in Table 3. ) were picked out and
separated into thr ee groups according to their lon-
g itudes. From south to north, the f irst g roup con-
sisted of the roo t samples f rom Zhejiang , Shan-
dong, L iaoning , Jilin and Heilongjian Prov inces,
r espect ively; the second group samples w ere from

was going up increasing ly with geographical loca-
tions mig rated f rom South to No rth, and high sig-
nif icant dif ference at 0. 01 level w as observed in the
mean of ox ymatrine content in every g roups based
on ANOVA ( T able 4) and LSD.

   This study also indicates that plant age be
po sit ively related to the total roo t biomass and
oxymatrine content . The ro ot biomass and oxyma-
trine content w ere going up year by year. How ev-
er, the rate of increase w as higher in the f irst thr ee
years ( Table 5) than that in the years soon at fer-
w ards.

   In conclusion, a signif icant v ar iat ion in the
r oot ox ymatrine content ex ists in S . f lavescens
plants depending on the geographical locat ions.
T he dif ference w ould appear to be related to ge-
netic variat ion among st plants g row ing in specif ic
natural habitat . Oxymatrine content w as increas-
ing with the increase in lat itude. On one hand, the
r esult of this wo rk may be useful for developing
simple, inexpensive and ef fective larg e-scale prop-
agat ion o f S . f lavescens to meet the demand of
o xymatrine. On the other hand, this information
can benef it the conservat ion of this species. Fur-
ther , S. f lavescens plant had long r oot and they
are likely to g row in sandy loam and they w ere re-
garded to be good at w ater and soil conserva-
t ion
[ 16, 17] , so this w o rk w ould also help to conserve
the genet ic div ersity at eco sy stem level.
