Pleurospermum lindleyanum (Lipsky)B.Fedtsch is a Chi-
nese folk medicine , used for the treatment of hyperten-
sion , coronary heart disease , high altitude sickness and
hepatitis in Xinjiang Uigur Autonomous Region.Previously
studies reported the isolation of 11 compounds from the
aerial parts of P.lindleyanum[ 1 ,2] .In the course of phy-
tochemical investigation on the whole plants , we obtained
15 known compounds , including three coumarins ,6 , 7-di-
hydroxycoumarin(1),(+)-marmesin(2)and marmesinin
(3), three flavonoids , 5 , 7 , 4′-trihydroxyflavone (4),
kaempferol 3-O-α-L-rhamnopyranoside (5)and luteolin
3′-O-β-D-glucopyranoside (6), one monoterpenoid ,(R)-
6-hydroxy-3-(2-hydroxypropan-2-yl)-6-methylcyclohex-2-
enone (7)and five aromatic acids , 4-hydroxybenzoic acid
(8),3-methoxy-4-hydroxybenzoic acid(9), 3-methoxy-4 ,
5-methylenedioxy benzoic acid (10), methyl syringate
(11) and methyl syringate 4-O-β-D-glucopyranoside
(12), as well as zingerone 4′-O-β-D-glucopyranoside
(13), 2-(4-hydroxyphenyl)-ethanol (14) and 1-octa-
cosanol(15).The above compounds were obtained from
the title plant for the first time and 7 was reported as nat-
ural product firstly.Here , we describe the isolation and
structure elucidation of these compounds.

Experimental
General
All melting points were determined on a BǜCHI 510 melt-
ing point apparatus and are uncorrected.Optical rotations
were measured using a Perkin-Elmer 341 polarimeter.IR
spectra were recorded on a Nicolet Magna 750 FTIR
(KBr)spectrometer.EI-MS data were obtained with a
MAT-95 mass spectrometer.NMR spectra were recorded
on a Bruker AV500 or Bruker DRX400 spectrometers , the
chemical shift values are reported in ppm(δ)and coupling
constants(J)are given in Hz.Silica gel(200 ~ 300 ,400
mesh)and precoated plates of silica gel(HSGF254)(Qing-
dao Haiyang Chemical Group Co.,Qingdao)were used for
column chromatography(CC)and TLC , respectively.
Plant material
The whole plants of P.lindleyanum were collected in
Tashikurgan ,Xinjiang Uigur Autonomous Region , China ,
in October 2000 , and identified by Prof.Guang-xing Yang
of Kashi Institute of Drug Research of Xinjiang.A voucher
specimen(No.0064)was deposited in our laboratory .
Extraction and isolation
The dried and powdered whole plants of P.Lindleyanum
(10 kg)were percolated with 95% EtOH(20 L ×3)at
room temperature.The concentrated extract was suspended
in H2O(3 L)and partitioned successively with petroleum
ether(PE , 60 ~ 90 ℃), CHCl3 , EtOAc , and n-BuOH(each 3 L×3).The CHCl3 fraction(77.4 g)was separat-
ed over silica gel column eluted with PE-Me2CO , PE-
CHCl3 , CHCl3-EtOAc , and CHCl3-Me2CO to give com-
pounds 2 , 7 ,9 , 10 , 11 and 15 , respectively.The EtOAc-
soluble fraction(33 g)was subjected repeatedly to CC on
silica gel eluted with CHCl3-MeOH , CHCl3-Me2CO , PE-
EtOAc , and CHCl3-EtOAc to yield successively com-
pounds 1 ,3 ,4 ,5 ,6 , 8 , and 14.The n-BuOH-soluble frac-
tion(145 g)was divided into H2O , 10%, 20%, 40%,
70%, and 95% EtOH subfractions through a macropore
resin D1400 (Yangzhou Pharmaceutical Factory ,
Yangzhou ,China)column( 10×65 cm).The 10%(6.6
g)and 20%EtOH(8.3 g)subfractions were further puri-
fied successively through silica gel , Sephadex LH-20 , and
ODS columns to afford compounds 12 and 13 , respective-
ly.
