Abstract: Five compounds(1-5)were isolated from the rhizome of Beesia calthaefolia (Maxim.)Ulbr.
Based on chemical and spectral evidence , their structures were determined as beesic acid(9_phenyl_2E , 4E ,
6E , 8E_nontetraenoic acid , 1), vanillic acid (2), oleanolic acid_3_O_α_L_arabinopyranosyl_28_O_α_L_

ranosyl_(1※3)_α_L_rhamnopyranosyl_(1※2)_α_L_arabinopyranosyl_28_O_α_L_rhamnopyranosyl_(1※4)_β_D_
glucopyranosyl_(1※6)_β_D_glucopyranosyl ester , 5), respectively .Compound 1 was isolated from natural
sources for the first time and compound 5 was a new compound.

  Beesia calthaefolia (Maxim.)Ulbr.(Ranuncu-
laceae)is widely distributed in southwest and northwest of
China.As a well_known Chinese folk herb medicine , it
possesses the functions of anti_inflammation , antipyretic ,
analgesia , detoxification and of invigorating blood circula-
tion.Its rhizome or the whole plant is used to treat cold ,
rheumatic arthritis , dysentery , sore throat , headache ,
etc[ 1] .Previous phytochemical research resulted in the
isolation of four highly oxygenated 9 , 19_cyclolanostane
triterpenic glycosides , namely beesioside Ⅰ-Ⅳ[ 2-5] .
For a continuation of our previous study[ 6 ,7] of the
constituents such as triterpenoids , sterols , 9 ,19_cy-
clolanostane triterpenic glycosides , etc., we isolated oth-
er two organic acids and three oleanane_type triterpenic
glycosides from the ethanol extract of the dried rhizomes of
Beesia calthaefolia.We report herein the structure eluci-
dation of these compounds.
1 Results and Discussion
Beesioside Q(5)showed a quasimolecular ion peak
at m/ z 1 405(M+K)+ , 1 389(M+Na)+ , 1 367(M
+H)+ in the ESI_MS , and the molecular formula
C65H106O30 was obtained by combined analysis of
1H-NMR
and 13C-NMR spectra.The IR spectrum exhibited absorp-
tion bands at 3 600-3 100 , 1 735 , 1 640 , 1 090 , 1 050
cm-1.The 1H-NMR spectrum showed the presence of six
anomeric proton signals(δ6.17(1H , d , J =8.0 Hz),
6.12(1H , brs), 5.77(1H , brs), 5.39(1H , d , J =
5.7 Hz), 4.94(1H , d , J =8.0 Hz), 4.75(1H , d ,
J =6.8 Hz)).The 13C_NMR spectrum showed the pres-
ence of six anomeric carbon signals(δ106.48 , 105.16 ,
104.63 , 102.59 , 101.44 , 95.53).The correlation

Fig.1. Structures of compounds 1-5.
Fig.2. Key correlations observed in HMBC of beesioside Q.
between each anomeric proton and its corresponding
anomeric carbon signal was also observed in the HMQC
spectrum.The above evidence suggested that compound 3
was a hexaglycoside.
The 1H_NMR spectrum showed the presence of seven
singlet methyl protons (δ0.83 , 1.85 , 0.86 , 1.03 ,
1.09 , 1.20 , 1.27), a trisubstituted olefinic proton (δ
5.36(t_like))and a methine proton signal(δ3.23(dd ,
J =11.0 , 4.0 Hz))in the aglycone moiety , which are
characteristic of an oleanane_type triterpene.A compari-
son of the 13C_NMR spectrum of the aglycone moiety of
compound 3 with that of oleanolic acid[ 8] revealed that C_
3 and C_28 of compound 3 exhibited remarkable glycosi-
dation shifts(δ)by +10.4 and +3.7 , indicating that
these two positions were linked with two sugar chains.
The ratio (3∶2∶1)of the three kinds of sugars(D_
glucose , L_rhamnose and L_arabinose)was established
by analysis of each group proton signals belonging to each
sugar moiety in the 1H_1H TOCSY spectrum.Two doublet
methyl protons(δ1.49 (3H , d , J =6.0 Hz , CH3),
1.63 (3H , d , J = 6.1 Hz , CH3))assignable to two
L_rhamnose moieties in the 1H_NMR spectrum supported
the above conclusion.Based on the 1H_1H COSY , 1H_1H
TOCSY , HMQC and HMQC_TOCSY spectra , all the 1H-
NMR and
13
C_NMR signals could be completely assigned(Tables 1 , 2).In the HMBC spectrum , the long_range
correlations were observed between each anomeric proton
signal and the sugar_linked carbon as shown in Fig.2.
Therefore , the sequence and binding sites of each sugar
were determined , which were substantiated by the frag-
ment ions at m/ z 1 205 (M-162+H)+ , 1 081(M-
162-146+Na)+ , 949(M-162-146-132+Na)+ ,
803(M-162-146-132-146+Na)+ in the ESI_MS.
A β_configuration at the anomeric position could be
inferred from the coupling constants for the three glucopy-
ranosyl units(J =5-8 Hz), whereas the α_configuration
at the anomeric position could be deduced from the cou-
pling constants for both the two rhamnopyranosyl units(J=0 Hz)and arabinopyranosyl unit (J =6.8 Hz).Ac-
cordingly , compound 5 was established to be oleanolic
acid_3_O_β_D_glucopyranosyl_(1 ※3)_α_L_rhamnopyra-
nosyl_(1※2)_α_L_arabinopyranosyl_28_O_α_L_rhamnopy-
ranosyl_(1 ※4)_β_D_glucopyranosyl_(1 ※6)_β_D_glu-
copyranosyl ester , named beesioside Q.
Beesic acid (1)was obtained as yellow powder(Me2CO), with mp of 220-224 ℃.Its IR spectrum in-
dicated the presence of hydroxy (3 600-3 300 cm-1),
conjugated carboxy (1 675 cm-1), conjugated double
bond (1 615 cm-1)and mono_substituted benzene ring
(1 595 , 1 565 , 1 445 , 750 , 690 cm-1).The UV spec-
trum of compound 1 exhibited absorption bands at λMeOHmax
342 , 350 , 368 nm , which suggested that compound 1
was an unsaturated aromatic acid.The EI_MS gave the
peak of molecular ion at m/ z 226(M+ , 100)consistent
with a molecular formula of C15H14O2 , confirmed by 1H-
NMR and
13
C_NMR spectra (Table 3).

The 1H_NMR spectrum of compound 1 showed a sig-
nal assignable to a carboxyl group (δ12.15 (1H , br.
s)), five aromatic signals due to a mono_substituted ben-
zene moiety (δ7.48(2H , d , J =7.6Hz), 7.33(2H ,
t , J =7.6 Hz), 7.24 (1H , t , J =7.6 Hz)), along
with another eight olefinic proton signals indicative of the
presence of four conjugated double bonds , as shown in
Table 3.The 13C_NMR spectrum displayed a total of 15
sp2 hybridized carbon signals(including two overlapped).
In the lowest field , a carboxyl group that appeared at δ
167.40 could be easily discerned , which was supported
by the presence of a peak at m/ z 181 ((M-COOH)+ ,
87)in the EI_MS spectrum.
The 1H-NMR and 13C_NMR signals were attributed
by using 1H_1H COSY and HMQC spectra.In the high-
field of the 1H-NMR spectrum , doublet signal (δ5.90(1H , d , J =15.2 Hz))can be assigned to H_2 , which
was adjacent to the carboxyl group(Fig.3).In the 1H_1H
COSY spectrum , the correlations among H_2/H_3 , H_3/
H_4 , H_4/H_5 , H_5/H_6 , H_6/H_7 , H_7/H_8 and H_
8/H_9 were observed(Fig.3).These findings , together

supported by the presence of a series of fragment ions at
m/ z 77(35), 63 (15), 51(20), and 39(15)in the
EI_MS spectrum.It was linked at C_9 of the above moiety
as the only possible site.An HMQC experiment was per-
formed and enabled complete assignment of all NMR sig-
nals(Table 3).Thus , the above evidence unambiguously
allowed us to establish the structure of compound 1 as 9_
phenyl_2E , 4E , 6E , 8E_nontetraenoic acid.Although
this compound has been reported by synthesized
method
[ 9] , as far as we could exhaust from the literature ,
compound 1 was isolated from natural sources for the first
time , named beesic acid.

2 Experimental
2.1 General experimental procedures
Melting points were determined on Fisher_Johns and
uncorrected.Optical rotations were measured with a
Perkin_Elmer 241 polarimeter.IR spectra were measured
with a Peking_Elmer 983G spectrometer.NMR spectra
were measured in pyridine_d5 with the Bruker AM_500
MHz spectrometers using TMS as internal standard.Au-
tospec_Ultima ETOF spectrometer was used to record ESI_
MS and FAB_MS spectra.Silica gel (400-500 mesh)
and D_101 resin were used for column chromatography.
2.2 Plant material
The rhizomes of Beesia calthaefolia(Maxim.)Ulbr.
were collected in Wen County , Gansu Province , China ,
in August 1998 and identified by Dr.CHEN Si_Bao , In-
stitute of Medicinal Plant Development , Chinese Academy
of Medical Sciences and Peking Union Medical College.
2.3 Extraction and isolation
The dried and pulverized rhizomes were extracted
with 95%EtOH and 50%EtOH each for two times.Af-
ter removal of solvent , the residue (950 g)was succes-
sively fractionated with CHCl3 and n_BuOH.The CHCl3
extract(292 g)was chromatographed on a column of sili-
ca gel(100-200 mesh)gradient eluting with petroleum
ether_EtOAc_MeOH (9∶1∶0-6∶3∶1)to give fractions 1-16.The fractions 1 -4 were combined and chro-
matographed on silica gel(400-500 mesh)eluting with
petroleum ether_EtOAc (10∶0-1∶9)and Sephadex_LH_
20(eluting with CHCl3_MeOH 1∶1)to yield compound 1(10 mg)and 2(0.75 g).The n_BuOH extract(105 g)
was chromatographed on D_101 resin and eluted succes-
sively with H2O and 95%EtOH.The fraction eluted with
95%EtOH was subjected to low pressure column chro-
matography over silica gel(400-500 mesh)by gradient
elution with CHCl3_MeOH_H2O(9∶1∶0.1-7∶3∶0.3)to
give fractions A-E.Fractions C , D and E were repeat-
edly chromatographed over silica gel under the above con-
ditions and Sephadex_LH20(eluting with MeOH_H2O 1∶
0.1), respectively , to afford compound 3 (60 mg), 4(3.5 g)and 5(4.5 g).
