Introduction
Inula helianthus-aquatica,a perennial plant belonging
to the Asteraceae family,is widely distributed in Yun-
nan,Sichuan,Gansu and Guizhou province of China
growing at 1200-3000 m above sea level [1]. It has
been used as a previous folk medicine to treat some
cancers in Yunnan [2]. So far,only 7 compounds have
been reported from this plant [3-5]. In order to make fur-
ther investigations on the aerial parts of I. helianthus-
aquatica,we isolated and identified twenty-four com-
pounds from an EtOAc extract of the whole plant,in-
cluding aromaticin (1) ,8-epi-helenalin (2) ,bigelovin
(3) ,2 3-dihydroaromaticin (4) ,carpesiolin (5) ,erg-
olide (6) ,inuchinenolide C (7) ,6α-acetoxy-isoinuvis-
colide (8) ,8-epi-inuviscolide (9) ,inuchinenolide B
(10) ,tomentosin (11) ,11α,13-dihydrotomentosin
(12) ,inuchinenolide A (13) ,4H-tomentosin (14) ,
11β,13-Dihydro-4H-tomentosin (15) ,11-epi-sundi-
versifolide (16) ,sundiversifolide (17) ,8,9,10-tri-
hydroxythymol (18) ,10-hydroxy-8,9-dioxyisopropyli-
denethymol (19) ,8,10-dihydroxy-9-isobutyryloxythy-
mol (20 ) ,8-hydroxy-9,10-diisobutyryloxythymol
(21 ) ,8-hydroxy-9-isobutyryloxy-10-(2-methylbu-
tanoyl)thymol (22) ,8,9-epoxy-3,10-diisobutyryloxy-
thymol (23) ,and 8,9-epoxy-3-isobutyryloxy-10-(2-
methylbutanoyl)thymol (24). All the compounds ex-
cept compounds 1-6 were isolated from this plant for
the first time.
Experimental
Instruments
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. J. T. Baker Acetonitrile (ACN)
was used as HPLC Solvent. Melting points were meas-
ured with an RY-2 micromelting point apparatus and
are uncorrected. ESI-MS were recorded on Q-TOF mi-
cro mass spectrometer. 1H and 13C NMR spectra were
measured on a Bruker DRX-500 spectrometer and
Bruker Avance DRX-400 spectrometer. Chemical shift
(δ)were given in ppm relative to TMS as internal ref-
erence and coupling constants (J)in Hz.
Plant material
The aerial parts of I. helianthus-aquatica were collected
from Nujiang river of Yunnan Province,China in Au-
gust,2007 and identified by Prof. Huang Bao-kang,De-
partment of Pharmacognosy,School of Pharmacy,Sec-
ond Military Medical University. A voucher specimen
(No. 200708XHFSCY)has been deposited at School
of Pharmacy,Shanghai Jiao Tong University.
Extraction and isolation
The air-dried and powdered aerial parts of I. helian-
thus-aquatica (1. 0 kg) were extracted with 95%
EtOH for three times at room temperature. After con-
centration of the combined extracts under reduced pres-
sure,the residue (86. 1 g)was suspended in H2O and
then partitioned successively with petroleum ether,EtO-
Ac and n-butanol,yielding 12. 1 g,14. 3 g and 11. 2 g,
respectively. The EtOAc fraction was chromatographed
on a silica gel column eluting with CH2Cl2-MeOH
(100∶ 1 to 10 ∶ 1)to obtain 5 fractions (A1-A5). A1
(1. 5 g)was applied to MCI gel column chromatogra-
phy (MeOH-H2O,9∶ 1)and purified by Sephadex LH-
20 (MeOH) ,yielding compounds 1 (5. 9 mg) ,2 (4. 0
mg) ,3 (4. 4 mg) ,4 (8. 7 mg). A2 (4. 1 g)was then
subjected to silica gel column again and eluted with
CH2Cl2-MeOH from 50∶ 1 to 10 ∶ 1 to give 5 sub-frac-
tions,the sub-fraction 2,3 were separated by prepara-
tive HPLC (RP18,210 nm,50% ACN)to give com-
pounds 5(14. 5 mg,tR = 19. 2 min) ,6(4. 0 mg,tR =
22. 4 min) ,7(5. 5 mg,tR = 25. 0 min) ,8(2. 9 mg,tR

min)and 17 (3. 4 mg,tR = 30. 3 min)were obtained
after the purifications of A3 (1. 3 g)by preparative
HPLC (RP18,210 nm,50% ACN). A4 (1. 7 g)was
chromatographed on MCI gel (MeOH-H2O,9 ∶ 1)and
Sephadex LH-20 (MeOH) ,and purified by preparative
HPLC (RP18,210 nm,40% ACN)to yield compounds
19 (2. 8 mg,tR = 30. 2 min) ,22 (5. 1 mg,tR = 34. 5
min)23 (3. 6 mg,tR = 48. 0 min)and 24 (6. 0 mg,
tR = 50. 5 min). A5 (2. 0 g)was also subjected to
MCI gel (MeOH-H2O,9 ∶ 1) ,Sephadex LH-20
(MeOH)chromatography,and purified by preparative
HPLC (RP18,210 nm,35% ACN)to give compounds
18(30. 8 mg,tR = 32. 8 min) ,20(12. 3 mg,tR = 36. 0
min)and 21(8. 5 mg,tR = 40. 4 min).
