【ABSTRACT】 AIM:Steroidal saponins were expected to be isolated from Paris polyphylla var.chinensis.METHOD:The
plant material was extracted with 95% EtOH;the crude saponins were chromatographed on a D101 , a silica gel and ODS col-
umn to afford the compound(Ⅰ).RESULT and CONCLUSION:On the basis of chemical methods and spectral evidences ,
compound(Ⅰ), named Parispolyside E , was confirmed as a new steroidal glycoside , possessing a homo-cholestane skeleton with
an aromatized ring E.And its structure was characterized as 3-O-α-L-arabinofuranosyl(1※4)[α-L-rhamnopyranosyl(1※2)]-
β-D-glucopyranosyl-β-D-chacotriosyl-26-O-β-D-glucopyranoside.

  Paris polyphylla var.chinensis , which is a famous
traditional Chinese medicine ,has been used for its an-
tibiotic and anti-inflammatory function , and has also
been used to treat injuries from falls , fractures ,parotitis ,
and hemostasis.Some steroidal saponins isolated from
Paris were reported with hemostatic and antitumor activ-
ity[ 1].
1 Experiment
1.1 Plant Material and Instruments
The roots of Paris polyphylla var.chinensis were
collected in Nantong , Jiangsu province in May 2003 ,
and then air-dried.The identity of plant material was
verified by Prof.Wang Qiang , and a voucher specimen is
kept in Department of Chinese Materia Medica Analy-
sis ,China Pharmaceutical University.
The melting point was obtained on a X-4 apparatus
and uncorrected.NMR spectra were measured in pyri-
dine d5 and recorded at BrukerAM-500MHz spectrome-
ter for 1H NMR , 13C NMR ,HMBC and HMQC.ESI-MS
spectra were recorded on a HP1100 LC/MSD TRAP.
Silica gel(200 ~ 300 mesh)was from Qingdao Ma-
rine Chemical Factory.All reagents were of analytical
grade.
1.2 Extraction and Isolation
Plant material(4 kg)was extracted with 95% E-
tOH , and concentrated in vacuum.The residue was sus-
pended inH2O and the solution was chromatographed on
a D101 macroreticular resin column eluting with H2O ,
40%, 80%, 95%EtOH successively.The 80%EtOH
fraction was concentrated in vacuum to give residue
crude saponins.This residue was chromatographed on a
silica gel and ODS column to afford 6 mg of compound
(Ⅰ).
Compound(Ⅰ)was named Parispolyside E , ob-
tained as an amorphous powder , mp 281 ~ 283 ℃,
[α] 25D-16.0(MeOH).It had the quasimolecular ion peak
at m/z 1023 [ M-H] - in the negative ESI-MS;UV
spectrum showed strong absorptions band at 277 and
336 nm for a benzene ring.TLC acid hydrolysis showed
that sugars in the molecule were glucose , rhamnose and
arabinose.And its structure was determined on the basis

of the following data.
The

H NMR spectrum showed the characteristic
signals at 0.94(3H , s ,H-18),1.11(3H , s ,H-19),2.32
(3H , s ,H-21), 1.05(3H , d , J =6.5 Hz ,H-27),5.35
(1H ,brs ,H-6),7.04(1H ,d , J =7.4 Hz ,H-22′),7.11
(1H ,d , J =7.4 Hz ,H-16′),which suggested the pres-
ence of three tertiary methyls , a secondary methyl , an
olefinic proton , tow aromatic protons , together with four
anomeric protons signals at 4.87(1H , d , J =8 Hz , glu
H-1),4.96(1H ,d , J =7.5 Hz , glu H-1),6.28(1H , s ,
rha H-1), 5.92(1H , s , ara H-1), and a methyl proton
1.78(3H , d , J =6.5 Hz , rha H-6).By extensive analy-
sis 13C NMR(Table 1),HMQC(Table 1)and ESI-MS
(m/z 1023[M-1] -※891[ 1023-132] -※745[ 891-
146] -※583[ 745-162] -)demonstrated that aglycone
moiety was a β-D-chacotriosyl moiety[ 2] and sugars in
the molecule were two β-D-glucopyranosyls , a α-L-
rhamnopyranosyl and a α-L-arabinofuranosyl[ 3] . Its
molecular formula was indicated to be C52H80O20。
