Introduction
The genus Inula,a variable perennial herb distributed
in Asia,Europe,Africa,and predominantly,in the Med-
iterranean,comprises ca. 100 species of the Asteraceae
family belonging to the tribe Inuleae [1]. The plant In-
ula hupehensis,the roots of which have been used to
treat many diseases,including bronchitis,diabetes,and
intestinal ulcers [2],is an endemic plant distributed in
Hubei and Sichuan Provinces in China. So far,only a
few compounds have been reported from this plant. In
order to do further investigations on the aerial parts of
I. hupehensis,we isolated and identified nineteen com-
pounds,including 9-hydroxythymol ( 1) ,8,10-dehydro-
9-hydroxythymol ( 2) ,2-hydroxy-4-methylacetophenone
( 3) ,8,9-dihydroxythymol ( 4) ,10-hydroxy-8,9- diox-
yisopropylidenethymol ( 5 ) ,8,10-dihydroxy-9-isobuty-
ryloxythymol ( 6) ,8-hydroxy-9-[( isobutyryl) oxy]-10-
( 2-methylbutanoyl) thymol ( 7) ,8,9,10-trihydroxythy-
mol ( 8) ,8-hydroxy-9,10- diisobutyryloxythymol ( 9 ) ,
neoechinulin A ( 10 ) ,3-formyl-indole ( 11 ) ,3-( hy-
droxyl-acetyl) - 1H-indole ( 12 ) ,syringic acid ( 13 ) ,
4,6-dihydroxy-2-methoxyacetophenone ( 14 ) ,daphne-
tin 7-methyl ether ( 15 ) ,6-methoxykaemaferol ( 16 ) ,
( + ) -syringaresinol ( 17 ) ,α-monopalmitin ( 18 ) ,and
stigmasterol ( 19 ) . All the compounds except com-
pounds 8 and 9 were obtained from this plant for the
first time.
Experimental
General procedures
The normal phase silica gel ( 200 ~ 300 mesh,Yantai,
China) ,MCI gel ( CHP20P 75 ~ 150 μm,Mitsubishi
Chemical Co.,Japan ) ,and Sephadex LH-20 ( GE
Healthcare Bio-Sciences AB,Sweden ) were used for
column chromatography,and precoated silica HSGF254
plates were used for TLC ( Yantai,China) . HPLC and
preparative HPLC were performed with SHIMADZU LC
2010AHT,Agilent Technologies 1200 series and SHI-
MADZU LPD-20A. Melting points were measured with
an RY-2 micromelting point apparatus and were uncor-
rected. ESI-MS were recorded on Q-TOF micro mass
spectrometer. 1H and 13C NMR spectra were measured
on a Bruker DRX-500 spectrometer. Chemical shift
( β) were given in ppm relative to TMS as internal ref-
erence and coupling constants ( J) in Hz.
Plant material
The aerial parts of I. hupehensis were collected from
Enshi city of Hubei Province,China ,in July,2007 and
identified by Prof. Huang Bao-kang,Department of
Pharmacognosy,School of Pharmacy,Second Military
Medical University. A voucher specimen ( No.
200707XHFHB) has been deposited at School of Phar-
macy,Shanghai Jiao Tong University.
Extraction and isolation
The air-dried and powdered aerial parts of I. hupehensis
( 25. 0 kg) were extracted with 95% EtOH for three
times at room temperature. After concentration of the
combined extracts under reduced pressure,the residue
( 3. 0 kg) was suspended in H2O and then partitioned
successively with petroleum ether,EtOAc and n-buta-
nol,yielding 230. 9 g,148. 3 g and 322. 6 g,respective-
ly. The EtOAc fraction was chromatographed on a silica
gel column eluted with CH2Cl2-MeOH ( 100% to
50% ) to obtain 7 fractions ( Frs. 1-7) . Fr. 1 ( 28. 5 g)
was applied to MCI gel column chromatography
( MeOH-H2O,4 ∶ 1 ) and purified by Sephadex LH-20
( MeOH) ,yielding compounds 7 ( 77. 1 mg) ,9 ( 443. 9
mg) and 19( 1103. 0 mg) . Fr. 2 ( 19. 6 g) was subjec-
ted to MCI gel ( MeOH-H2O,4: 1 ) ,Sephadex LH-20
( MeOH) chromatography,and purified by preparative
HPLC ( RP-18,210 nm,45% MeOH ) to give com-
pounds 1( 6. 1 mg) ,2( 3. 0 mg) ,3 ( 42. 5 mg) ,5 ( 9. 0
mg) ,10( 29. 7 mg) ,11 ( 5. 1 mg) ,13 ( 58. 3 mg) ,14
( 4. 0 mg ) ,15 ( 7. 2 mg ) and 18 ( 100. 8 mg ) . Com-
pound 6( 53. 7 mg) was obtained after the purifications
of Fr. 3 ( 11. 6 g) by MCI gel ( MeOH-H2O,4∶ 1) and
Sephadex LH-20 ( MeOH) chromatography. Fr. 4 ( 9. 3
g) was chromatographed on MCI gel ( MeOH-H2O,4∶
1) and Sephadex LH-20 ( MeOH ) ,and purified by
preparative HPLC ( RP-18,210 nm,45% MeOH ) to
yield compounds 4 ( 21. 7 mg) ,8 ( 5. 1 mg) and 12
( 2. 0 mg) . Fr. 5 ( 6. 5 g) was subjected to MCI gel
( MeOH-H2O,4∶ 1 ) ,Sephadex LH-20 ( MeOH) chro-
matography,and purified by preparative HPLC ( RP-
18,210 nm,40% MeOH ) to give compounds 16
( 301. 8 mg) and 17( 12. 3 mg) .
