S abina vulgaris Ant (Cupres-saceae: Sabina) is a creepingevergreen shrub. S. vulgaris
has ecological function, and its branch-
es, leaves and seeds can be used as
medicine, treating a variety of dis-
eases[1]. S. vulgaris is an important na-
tive species in arid and semi-arid
desert areas of northwest China, and it
plays an important role in maintaining
the ecology. S. vulgaris is also a new
tree species in the garden construction
of northern cities. Particularly impor-
tant, S. vulgaris is an excellent insecti-
cidal plant first discovered and report-
ed in China, and it has great develop-
ment and utilization prospects [2]. With
the advance of science and technolo-
gy and development of production
technology, production processes of
food industry have become increas-
ingly mechanized. The disinfection as-
pect of production needs more safe
disinfectants, and the application of
chemical disinfectants in food produc-
tion has been criticized. Therefore, it is
urgent to find a green and sate disin-
fection product. S. vulgaris essence oil
is a kind of natural plant oil extracted
from S. vulgaris. It has been reported
that S. vulgaris essence oil not only
has insecticidal activity[3-4], but also has
significant bactericidal effect with in-
hibitory effects on most pathogenic
bacteria[5-6]. In this study, the bacterio-
static effect of waste liquor of S. vul-
garis essential oil extraction was inves-
tigated to determine whether the
waste liquor had bacteriostatic effect,
as well as the intensity of the bacterio-
static effect, thereby providing a new
synergistic approach for essence oil
extraction enterprises and a theoreti-
cal basis for the development of S.
vulgaris essential oil extraction waste
liquor as a food disinfectant.

Abstract The antibacterial effects of waste liquor of essence oil extraction from
Sabina vulgaris Ant on Escherichia coli, Staphylococcus aureus, Salmonella, Bacillus
subtilis, Bacillus magaterium and Bacillus cereus in foods were evaluated by paper
disk method. The results showed that the waste liquor of essence oil extraction
from S. vulgaris had inhibitory effects on E. coli, S. aureus and Salmonella with bet-
ter inhibitory effects on E. coli and Salmonella; the bacteriostatic effect of water
steam distillation waste liquor was better than that of water extraction waste liquor.
The more times the waste liquor was distilled, the higher the active ingredients
content was, and the better the bacteriostatic effect was.

Medium
The formula of beef extract pep-
tone medium was as follows: beef ex-
tract 3 g, peptone 5 g, NaCl 5 g, agar
15-20 g, deionized water 1 000 ml and
pH 7.4-7.6. After the preparation, the
beef extract peptone medium was
sterilized at 121℃ for 30 min.
Waste liquor of essence oil extrac-
tion from S. vulgaris
In this study, there were two kinds
of waste liquor of essence oil extrac-
tion from S. vulgaris (referred to as
waste liquor), water steam distillation
waste liquor and water extraction
waste liquor. When the plant coarse
powder was soaked in water and then
heated directly, the water and essence
oil were distilled out; after cooled, the
essence oil was separated. This was
defined as water extraction. When the
plant coarse powder was placed in a
distiller and then distilled with water,
the essence soil, along with water
steam, was distilled out. This was de-
fined as water steam distillation. The
waste liquor was filtered with filter pa-
per. The distillation pots were num-
bered, sealed and preserved at 4 ℃
for use.
Preparation of bacterial suspen-
sions
The indicator strains were picked
out from agar slants and inoculated in
liquid medium, respectively. After 24-h
culture, a certain amount (200 μl) of
each bacterial suspension was trans-
ferred to a conical flask filled with 10-
ml sterile saline or sterile water and os-
cillated for 10 min. The concentration
of the bacterial suspensions was about
105 CFU/ml.
Determination of antibacterial ac-
tivities
The antibacterial activities were
determined by paper disk method [7]. A
certain number of small round pieces
of paper with diameter of 6 mm were
prepared by a hole puncher. They
were dry-heat sterilized and soaked in
different waste liquors. In the control
group, the small round pieces of paper
were soaked in sterile saline. The
cooled (to about 50 ℃ ) beef extract
peptone agar medium was poured into
sterile plates, which were placed hori-
zontally. After the medium was solidi-
fied, a certain amount (200 μl) of each
bacterial suspension was added to the
plates, and coated evenly with a sterile
triangle bar. In each of the plates, total
3 pieces of paper were tiled evenly.
Among them, 2 pieces were soaked in
the same waste liquor, while the re-
maining one was soaked in sterile
saline (control). The plates, along with
filter papers, were placed in an incuba-
tor (37 ℃ , 24 h). Finally, the sizes
(horizontal and vertical diameters) of
the inhibition zones were measured by
a vernier caliper. The test was repeat-
ed three times. The final data were ex-
pressed as the means of the 3 repli-
cates[8].
Results and Analysis
Antibacterial effects of S. vulgaris
essence oil extraction waste liquor
on indicator strains
As shown in Table 1, the water
steam distillation waste liquor and wa-
ter extraction waste liquor showed an-
tibacterial effects on E. coli, S. aureus
and Salmonella in varying degrees, in-
stead of B. subtilis, B. magaterium and
B. cereus. Among the 3 strains, the
antibacterial capacities of S. vulgaris
essence oil extraction waste liquor
ranked as E. coli > Salmonella > S.
aureus. The inhibition zones of S. vul-
garis essence oil extraction waste
liquor for E. coli and Salmonella were
larger, i.e., better inhibitory effects on
E. coli and Salmonella. However, the
inhibition zone of S. vulgaris essence
oil extraction waste liquor for S. aureus
was smaller, i.e., poor inhibitory effect
on S. aureus. The bacteriostatic ca-
pacity of S. vulgaris essence oil ex-
traction waste liquor differed between
different extraction methods. The bac-
teriostatic capacity of water extraction
waste liquor was weaker than that of
water steam distillation waste liquor.
Comparison of antibacterial effects
of S. vulgaris essence oil extraction
waste liquor on indicator strains
between different extraction meth-
ods
The S. vulgaris essence oil ex-
traction waste liquor was divided into
water steam distillation waste liquor
and water extraction waste liquor. For
water steam distillation waste liquor,
under the condition of same-pot water,
the active ingredients content in waste
liquor was different for different distilla-
tion time. As shown in Table 2, the ac-
tive ingredients content in water steam
distillation waste liquor was increased
with the increased distillation times,
thus the bacteriostatic activity of the
waste liquor was increased with the
increased distillation times; the active
ingredients content in water extraction
waste liquor was lower, so its antibac-
terial capacity was weaker.
Conclusions
The S. vulgaris essence oil ex-
traction waste liquor had better an-
tibacterial activities for E. coli and
Salmonella and relatively low antibac-

one person in the same day, and the
survey methods and tools should be
consistent, to achieve timely, careful,
detailed, and objective survey.
Records of the field survey include
meteorological conditions, farming op-
eration, crop growth and development
situation, and plant diseases and in-
sect pests. It is required to make a
truthful record of special climatic condi-
tions in the process of experiment, un-
expected natural and human factors,
and circumstances that have serious
influence on experiment, such as
floods, droughts, and human and live-
stock hazards. Abandonment of exper-
iment (if any) should be reported in
written form in a timely manner.
Harvesting and seed evaluation
Harvesting in suitable time
Maize can be harvested when
maize bracts become loose and yellow
and there are black layers in the base
of bracts.
Field record and sampling
Before harvesting of a block, first-
ly reap the guard row, then take field
survey on actually harvested rows:
quantity of lack of plants, actually har-
vested plants, quantity of empty ears,
quantity of plants with two ears, quan-
tity of decayed ears, and quality of
maize grains. For harvested maize,
weigh the fresh ears and take sam-
ples, pack samples of each block into
mesh bags and hang the bags out-
doors for drying and seed evaluation. It
is required to make strict harvesting,
shelling, drying, and yield calculation
by blocks.
Indoor seed evaluation
For indoor seed evaluation, it is
required to select precise instrument to
measure and make a record of ear
shape, ear length, ear thickness, tip-
barren length, ear row number, quan-
tity of row grains, grain type, grain col-
or, and ear axis color, and dry maize
by blocks. After maize is dried to con-
stant weight, measure moisture con-
tent of each block with a moisture ana-
lyzer (measuring three times and cal-
culating the average value), and con-
vert into the yield of regional experi-
ment as per 14% maize standard
moisture content.
Conclusions
Finally, it is required to draft for-
mats and requirements according to
the experiment scheme, make truthful,
objective, reliable and comprehensive
evaluation on agronomic traits such as
adaptability, yielding ability, stress, dis-
ease-resistance, and external charac-
teristics, and submit standardized ex-
periment report to competent authori-
ties.
