Analysis of essential oil from medicinal and non-medicinal parts of Atractylodes chinensis and antibacterial activity in vitro
To explore the difference in chemical components of essential oil from medicinal part (rhizome) and
non-medicinal parts (fibrous roots, stems, and leaves) of
Atractylodes
chinensis
, and to preliminarily evaluate their antibacterial activity
in vitro
.
METHODS
2
The essential oil was extracted from three parts of
A. chinensis
by steam distillation, and their chemical components and relative contents were analyzed and identified by gas chromatography-mass spectrometry (GC-MS). The antibacterial activities of essential oil (5 mg/mL) from different parts against
Staphylococcus aureus
,
S. albus
and
Bacillus subtilis
were determined by paper diffusion method. The correlation between chemical components in essential oil and antibacterial activity was analyzed.
RESULTS
2
A total of 60 chemical constituents were identified from the essential oil of rhizome, fibrous roots, stems and leaves of
A. chinensis
, mainly composed of terpenes, sesquiterpenoids, alcohols and ketones. There were 8 kinds of common components in the essential oil of rhizome, fibrous root and stem and leaves, which were elementol, cadinene, agarospirol, valencian citrine, caryophyllin,
β
-sesquidiene,
γ
-eucalyptol and
β
-eucalyptol. A total of 26 components were identified from the essential oil of rhizome, of which the relative content of 4-benzaldehyde was the highest (31.56%); a total of 21 components were identified from the essential oil of fibrous roots, among which the relative content of
β
-eucalyptol was the highest (44.39%); a total of 42 components were identified from the essential oil of stems and leaves, among which the relative content of
β
-sesquidiene was the highest (14.83%). The essential oil from different parts had certain antibacterial effect on
S. aureus
,
S. albus
and
B. subtilis
. The order of antibacterial ef
fect was rhizome>fibrous roots>stem and leaves; the relative contents of
β
-caryophyllene,
α
-humulene and modhephene were positively correlated with
inhibitory effects of
essential oil against
S. aureus
and
B. subtilis
(
P
<0.05 or
P
<0.01). The relative contents of atractylone, zingiberene and agarospirol were positively correlated with the inhibitory effect of essential oil against
B. subtilis
(
P
<0.05 or
P
<0.01).
CONCLUSIONS
2
There are significant differences in the chemical composition and contents of essential oil from medicinal and non-medicinal parts of
