Objective: The contents of main active ingredients, antioxidant and cholate binding ability of different ethanol extracts from Psoralea corylifolia L. were explored based on the mode of correlation of “components-efficacy”. Methods: Psoralea corylifolia L. was extracted with anhydrous ethanol, 75% ethanol, 50% ethanol and water. The contents of total flavonoids and total polyphenols in Psoralea corylifolia L. were determined. The antioxidant and lipid-lowering activities in vitro of Psoralea corylifolia L. were evaluated by three antioxidant systems and the binding ability of cholate salts, respectively, and the correlation analysis was conducted. Results: The contents of total flavonoids and total polyphenols in anhydrous ethanol extract were the highest, (50.317±0.018) mg/g and (3.860±0.045) mg/g, respectively. The 50% ethanol extract showed the best ability to scavenge ABTS＋· and DPPH·, the IC50 values were 0.76 and 1.63 mg/mL, respectively. The anhydrous ethanol extract showed the strongest reducing ability, the A0.5 value was 2.63 mg/mL. The water extract showed the strongest binding capacity to sodium cholate, the IC50 value was 0.67 mg/mL. The 50% ethanol extract showed the strongest binding capacity to sodium taurocholate and sodium glycinate, the IC50 values were 1.26 and 0.41 mg/mL, respectively. The correlation results showed that the content of total flavonoids of different ethanol extracts from Psoralea corylifolia L. had a significant positive correlation with DPPH· clearance rate and sodium taurocholate binding rate (P

To optimize the ultrasound-assisted three-phase partitioning for the simultaneous extraction of allicin and polysaccharides from garlic. The effect of polyethylene glycol (PEG) concentration, ammonium sulfate concentration, sonication temperature, and sonication time on the extraction efficiency of allicin and polysaccharides were investigated, respectively. The simultaneous extraction process conditions of allicin and polysaccharides were optimized according to the Box-Behnken experimental design. Results showed that the optimal conditions were PEG concentration of 24%, the ultrasonic temperature of 34 °C, and ultrasonic time of 50 min. Under these conditions, the extraction efficiency of allicin and polysaccharide was calculated according to the anhydrous calculation, reaching 3.564 and 43.86 mg/g, respectively. The optimized extraction process could effectively and simultaneously extract allicin and polysaccharides from garlic, which would provide a foundation for the deep research, development, and application of functional products from natural garlic.

The development and application of new configurations inspired by the folding principle of origami is increasingly becoming a research hotspot in related fields. Among them，the design of plane crease，the folding of three-dimensional shape，the motion characteristics of configuration，the degree of freedom and the corresponding driving design are all scientific problems to be solved. Based on the classic Water-Bomb origami basic unit，the plane crease of the non-convergence foldable unit with single degree of freedom is designed. The combination design and three-dimensional （3D） folding design of the basic crease are carried out，and two kinds of 3D units with certain stiffness and folding motion are obtained，namely the foldable prismatic pair and the foldable rotation pair. At the same time，inspired by the foldable rotation pair，a software actuator cooperating with the basic non-convergence unit is designed，and combined with two kinds of 3D units，a stable control of the 3D units is realized. In the experiment，it is found that the control of the input angle of the 3D unit by the software actuator can control the stiffness of the 3D unit simultaneously. The origami leg and walking robot are designed by connecting the two kinds of three-dimensional units in series，and the walking simulation experiment and the step crossing experiment of the robot are implemented. The maximum margin of the origami leg of crossing the step is obtained，and the special performance of the two kinds of variable stiffness units in the process of walking and stepping is verified.

In view of the limitations of walking robots such as complex driving and inability to adapt to different walking environments， a new type of single-degree-of-freedom walking robot with two leg origami configurations based on the origami mechanism is designed， by folding Miura origami crease angle theory is combined with leg equivalent kinematics model， the kinematics solution is simplified and a new driving mode is designed. The theory of single-vertex origami is extended to the multi-vertex origami configuration， and the definite relationship between the crease corners of different units is obtained. A gait plan that matches the folding state of origami is proposed. The simulation results show that the origami configuration of the robot legs can achieve a long-span and long-span walking gait. Due to the large-span motion at the end of the foot， it does not slide relative to the ground， can achieve smooth walking on roads of different complexity.
