Abstract:Eight compounds were isolated and purified by solvent extraction,repeated chromatography with silica gel,
Sephadex LH-20 and RP-C18 from Paris fargesii Franch. Then their structures were identified by spectral of analysis asβ-
sitosterol(1) ,β-ecdysterone(2) ,Paris Saponins Ⅴ(3) ,Paris SaponinsⅠ(4) ,Paris SaponinsⅡ(5) ,Paris SaponinsⅦ
(6) ,Paris Saponins H(7) ,Paris SaponinsⅥ(8). Compounds 1-8 were isolated from Paris fargesii Franch for the first
time.
Key words:Paris fargesii Franch.;chemical constituents;steroidal saponins
Introduction
The genus Paris belongs to the family Liliaceae and is
mainly distuibuted in the regions of Eurasia from the
temperate zone to the tropics. There are 19 species of
grown in southeast China,and many of them have been
used as traditional Chinese medicine for a long time,
such as Paris polyphylla Smith var. chinensis and P.
polyphylla Smith var. yunnanensis[1]. The rhizomes of
genus Paris have been used not only as anti-cancer,an-
ti-biotic,and anti-inflammatory drug but also to treat
traumatic injuries,snake bite,abscess,parotitis,and
mastitis. In the previous papers,we reported the isola-
tion of a series of steroidal saponins from the roots of
geuns Paris[2-5]. However,the chemical constituents of
P. fargesii Franch have not been investigated. As part
of our chemical investigation on the plants of genus
Paris,this paper presents the isolation and structural
elucidation of eight compounds from the rhizomes Paris
fargesii Franch,these compounds were isolated from
this plant for the first time.
Experimental
General
Melting points were determined on an X-4 melting
point apparatus and are uncorrected. NMR spectrum
was recorded on INOVA 500(Varian). The chemical
shifts are represented as part per million(ppm)refer-
enced to the residual solvent signal. Preparative HPLC
(PHPLC)was carried out on an ODS-A column(25 ×
2 cm i. d.,YMC)with a JASCO RI-1530 intelligent
refractive index detector. Silica gel(100-200,200-300
mesh,Qingdao Ocean Chemical Group Co. of China) ,
YMC gel ODS-A,50 μm(YMC)and Sephadex LH-20
(Merck Co.) for column chromatography as well as
silica gel GF254(Qingdao Ocean Chemical Group Co. of
China)for TLC were used.
Plant material
The rhizomes of Paris fargesii Franch. were purchased
from the Yunnan Province,Peoples Republic of China
and was identified by Professor Wen-Yuan Gao (Tian-
jin University,China). A voucher specimen (no.
200818)has been deposited in the School of Pharma-
ceutical Science and Technology,Tianjin University,
China.
Extraction and Isolation
The rhizomes of Paris fargesii Franch. (1. 5 kg)were
powdered and successively extracted three times with
95% and 65% EtOH under reflux and filtered. Evapo-
ration of the solvent under reduced pressure. The ex-
tract was dissolved and suspended in H2O,and parti-
tioned with petroleum ether,EtOAC and n-BuOH. The
EtOAC fraction(10g)was subjected to column chroma-
tography over silica gel using a CH2Cl2-CH3OH[100
∶ 0-60∶ 40]step gradient system to provide twelve frac-
tions which were further pruified by Sephadex LH-20
and recrystallization to afford compound 1(15 mg).
The n-BuOH fraction was chromatographied on macro-
porous resin D101 eluted with a gradient mixture of
EtOH– H2O (0∶ 100,30∶ 100,50∶ 50,70∶ 30,100∶ 0)
to give five fractions(A—E). Fractions D(70% n-
BuOH)was further isolated and purified through silica
gel,ODS,and HPLC-ODS-A by elution with MeOH:
H2O,leading to the isolation of compound 2(40 mg) ,3
(20 mg) ,4(15 mg) ,5(12 mg) ,6(13 mg) ,7(10
mg) ,and 8(10 mg).
