The purpose was to establish a characteristic fingerprint of Eucommia ulmoides leaves extract, a feed additive, using high-performance liquid chromatography (HPLC), to provide a reference for its quality control. The HPLC method was used to determine the chemical constituents of 36 batches of Eucommia ulmoides leaves extract on a Sunfire C18 (4.6 mmx250 mm, 5 µm) column, with acetonitrile-0.1% formic acid in water as the mobile phase, at a flow rate of 1.2 mL/min, with an injection volume of 10 µL, a column temperature of 35 °C, and a detection wavelength of 254 nm. Eight peaks with better separation and peak shape in the chromatograms of 36 batches of Eucommia ulmoides leaves extracts were selected as the characteristic peaks to obtain the HPLC chromatograms of Eucommia ulmoides leaves extract. Based on the information of the control product, the precise relative molecular mass and the fragmentation ions, eight characteristic peaks were identified as the constituents of Eucommia ulmoides leaves extract. The results showed that a total of eight characteristic peaks were identified in the HPLC characteristic chromatogram of Eucommia ulmoides leaves extract, and seven chromatographic peaks of aucubin, geniposidic acid, neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, quercetin rutin, and isoquercitrin were identified. The study indicates that the characteristic chromatogram of Eucommia ulmoides leaves extract established in the experiment has achieved stable quality control and can provide reference for the quality evaluation of Eucommia ulmoides leaves extract as a feed additive.

In order to understand the effect of Eucommia ulmoides leaf water extract (ELWE) on probiotic characteristics in vitro of Lactobacillus plantarum, the effects of different concentrations of ELWE on the growth curve, acid-producing ability, morphology and tolerance of Lactobacillus plantarum were studied by means of bacteria count, scanning electron microscope and gas chromatography, respectively. The results show that the number of viable bacteria in the experimental groups were significantly higher than that of the control group after 24 h cultivation. High concentrations of ELWE (80, 320 mg/mL) make Lactobacillus plantarum fuller, and can significantly improve the lactic acid production capacity of Lactobacillus plantarum, and the lactic acid content increase by 42.07% and 111.64% after 36 h cultivation, respectively. Under the stress of gastric juice environment, the logarithmic survival rate of 80 mg/mL ELWE group can reach 87.77% (3 h), which is significantly higher than that of the control group (0%). And 80 mg/mL ELWE treatment can significantly increase the viable count of Lactobacillus plantarum under heat stress, NaCl stress, bile salt stress and vacuum freeze-drying stress, and the viable count can be maintained at 5.67, 8.16, 7.65, 7.78 lg CFU/mL, respectively. 80 mg/mL ELWE has a positive effect on the in vitro probiotic characteristics of Lactobacillus plantarum. This study provides the necessary theoretical reference for the application of ELWE in probiotic industry. [ABSTRACT FROM AUTHOR]
