“…Determination of syringin by HPLC‐DAD was performed according to the methods described in literature [17] . The details are as follows: 1.00 mg/mL syringin solution was prepared and diluted into a series of syringin reference solutions of 1.37, 4.12, 12.35, 37.04, 111.11, 333.33, 1000.00 μg/mL, respectively.…”

The quality of traditional Chinese medicines (TCM) has a significant correlation with the source and growth years. However, there is no research on the relationship between the growth period and the quality of Codonopsis Radix (CR). This work aims to evaluate the quality of CR in different growth years (2–5 years). First, the content of 6 efficacy‐related and 28 nutrient‐related components in different growth years of CR was analyzed. The results showed that with the increase in growth years of CR, the content of some components increased, while some decreased. Then, the AHP‐CRITIC method was performed to score the CR in different growth years, the results showed that the comprehensive score of CR increased with the increase of growth years, and the 5‐year‐CR had the highest score. Finally, in vitro activity assays were designed to verify the evaluation results. The results demonstrated that with the increase of growth years, the spleen lymphocyte proliferation activity and DPPH free radical scavenging activity of CR were enhanced, which proved that the AHP‐CRITIC method is reasonable to evaluate the quality of CR in different growth years. The aforementioned findings demonstrated that CR quality improved with longer planting years.

“…Since the deformation damage of rock is mainly due to energy dissipation, it is a very effective method to reveal microwave radiation damage by using energy dissipation theory. Yang, J et al [15], Tang, M et al [16], and Hassani, F et al [17] analyzed the loaded energy evolution process of rocks after microwave damage based on the dissipated energy theory, and the results showed that the weakening of rocks by microwave irradiation not only reduces the degree of energy storage in rocks and increases the proportion of its dissipated energy during the damage process, but also reduces the rate of elastic energy release after the peak. Most of the studies on microwave numerical simulation are based on COMSOL finite element software.…”

To study the dynamic response of granite to different levels of microwave power, an intelligent microwave rock-breaking instrument is used to irradiate different power from three directions. The servo universal testing machine is used to carry out a uniaxial compression test on the granite after microwave damage to analyze the strength damage characteristics and the degree of pore damage. Pore fractal characteristics are analyzed based on nuclear magnetic resonance to establish the microwave damage degradation model. In parallel, the energy evolution process of granite under the influence of various power levels is analyzed using the theory of energy dissipation. Simultaneously, based on the energy dissipation theory, we analyze the energy evolution process of granite under the action of different powers. The results show that with higher microwave power, the peak strength and modulus of elasticity show a linear decreasing law. The degree of fragmentation is more obvious, showing the damage characteristics with two big ends and little in the middle. The higher the power, the greater the porosity and the more sensitive the micropore becomes to microwaves. Additionally, the damage degradation model established to evaluate the microwave damage of the rock showed that it was feasible. The higher the power, the lower the total energy, elastic energy, and dissipation energy, and the granite is gradually transformed from elastic deformation to plastic deformation. The elastic energy ratio decreases, the dissipation energy ratio increases, and the degree of damage becomes more and more serious. This study provides theoretical support for exploring the mechanical behavior and mechanism of microwave-assisted rock breaking and is of great practical significance.
