[ABSTRACT] AIM: To study the chemical constituents of Monochasma savatierii Franch.. METHODS: The chemical constituents
were isolated and repeatedly purified by column chromatography with silica gel, Rp-C18, Sephadex LH-20 and identified by IR, MS
and NMR. RESULTS AND: Eight compounds were obtained and identified as 7, 8-dehydroboschnialactone (1), argyol (2), liquirti-
genin (3), β-sitosterol (4), p-hydroxycinnamic acid (5), 2-hydroxy-4-methoxybenzonic acid (6), p-hydroxyphenylethanol (7), proto-
catechuic acid (8). CONCLUSION: Compound 1 was obtained from natural source for the first time and the others have been isolated
from this plant for the first time.

1 Introduction
Monochasma savatieri Franch., known as “Longxucao ,
Baitouweng” etc. in China, is widely distributed in southern
China [1]. This plant was widely used in the treatment of
common cold, cough, bloody flux, menoxenia, toothache,
mammary abscess in Traditional Chinese Medicine. As for
the chemical constituent of this plant, only some phenols and
revertoses were reported. During our research, eight com-
pounds were isolated from this plant. These compounds were
identified as 7, 8-dehydroboschnialactone (1), argyol (2),
liquirtigenin (3), β-sitosterol (4), p-hydroxycinnamic acid (5),
2-hydroxy-4-methoxybenzonic acid (6), p-hydroxy- phenyle-
thanol (7), protocatechuic acid (8). Compound 1 was ob-
tained from natural source for the first time.

(MAT-95, Finigan); Silica gel GF254 plates (Yantai Jiangyou
Chemical Co., Ltd.). Silica gel (300−400 mesh; Yantai Jian-

gyou Chemical Co., Ltd.); Sephadex LH-20 (GE Healthcare
Bio-Sciences AB); Rp-C18 gel (ODS-A 12 nm, s-50 μm, Ja-
pan); MCI resin (75−150 μm, Mitsubishi Chemical Corpora-
tion).
2.2 Plant material
The herb of Monochasma savatieri Franch. was col-
lected in Qiandaohu of Zhejiang Province, China, in June
2009, and botanically authenticated by author TAN Xing-Qi.
3 Extraction and Isolation
The air-dried herb of Monochasma savatieri Franch.(10
Kg) were ground and extracted with 75% EtOH (doused for
10 d), the extracted liquid was combined and concentrated in
vacuum on a rotary evaporator to afford a residue, which was
suspended in water and extracted with CHCl3. The CHCl3
fraction (64 g) was subjected to silica gel column chroma-
tography, being eluted with CHCl3−MeOH (20 : 1, 10 : 1, 8 :
1, 5 :1) to provide fractions 1−4. They were subjected respec-
tively to repeated column chromatography on silica gel,
Sephadex LH-20, Rp-C18 gel and MCI resin column chroma-
tography to give compounds 1, 2 and 4. The water layer (138
g) was subjected to macroporous resin column chromatogra-
phy, being eluted with EtOH−H2O [0% (1), 20% (2), 60% (3),
95% (4)] to provide fractions 1−4. Frs. 2 and 3 were sub-
jected to chromatography on silica gel column and then puri-
fied by Sephadex LH-20, Rp-C18 gel and MCI resin column
chromatography to give compounds 3, 5−8.

Compound 1 White crystal; mp 40−41 °C; ESI-MS
m/z 151 [M − H]−, C9H12O2. Compound 1 was identified as 7,
8-dehydroboschnialactone by comparison of the physical and
spectral data with the literature [2], In the article, 1 was re-
ported as synthetic intermediate. So the compound 1 was
obtained from natural source for the first time. The 1H- and
13C NMR data are shown in Table 1.
