Chemical Constituents of Corydalis impatiens and Their Inhibitory Effect on Proliferation of Hepatoma Cells
To systematically investigate the chemical constituents of 90% ethanol extract of
Corydalis impatiens
,and evaluate their inhibitory effect on cell proliferation
in vitro
.
Method
2
The chemical constituents were isolated and purified by silica gel,Sephadex LH-20,ODS column chromatography and semi-preparative high performance liquid chromatography (HPLC).the structures were identified by spectroscopy methods such as NMR and MS,as well as analysis of physicochemical properties and/or comparison with literature data,and the inhibitory activities of 13 compounds on HepG2 and SMMC-7721 cells were measured by methyl thiazolyl tetrazolium (MTT) method.
Result
2
Thirteen known compounds were isolated and identified from 90% ethanol extract of
Corydalis
impatiens as ethyl-5-hydroxy-2-pyridinecarboxylate(
1
),coryhumolide(
2
),3,4-
cis
-3,4-dihydroxy-
β
-ionone(
3
),megastigmane(
4
),9-hydroxy-4,7-megastigmadien-3-one(
5
),blumenol A(
6
),indole-3-carboxy acid(
7
),1-methyl-[1,2,4]triazolo[4,3-b]
[1,2,4]triazin-7-one (
8
),adenine(
9
),nicotinamide(
10
),2-hydroxymethyl-5-pyridinol(
11
),adenosine(
12
), and
β
-daucosterol(
13
). Cytotoxicities assay showed that the IC
50
value of compound
3
for the hepatic cell line HepG2 was 24.7 μmol·L
-1
(positive control drug cisplatin:4.8 μmol·L
-1
),and IC
50
value of compound
4
for the hepatic cell line SMMC-7721 was 13.8 μmol·L
-1
(positive control drug cisplatin:5.4 μmol·L
-1
).
Conclusion
2
Compound
1
was a new natural compound,compounds
3-8
were obtained from genus
Corydalis
for the first time,and compounds
2
,
9-12
were isolated from this plant for the first time. Compound
3
exhibited weak inhibitory effect on hepatic cell line HepG2,and compound
4
exhibited moderate inhibitory effect on hepatic cell line SMMC-7721.The other compounds rest of ones exhibited no obvious inhibitory effect on hepatic cell line HepG2 or SMMC-7721.
