Macroporous polymeric resin for the purification of flavonoids from medicinal plants: A review.

The purification of flavonoids using the macroporous polymer resin method has gained attention in recent years due to its simplicity, precision, cost-effectiveness, and the ability to separate flavonoids from other constituents. Several studies have been conducted to investigate the efficiency and effectiveness of macroporous polymer resin in purifying flavonoids from various plant sources. This review aims to evaluate the existing literature on macroporous polymer resin purification of flavonoids and provide a comprehensive analysis of the current research trends and advancements in this field. It also highlights the importance of optimizing the adsorption parameters and conditions such as resin type, resin concentration, pH, and temperature for efficient purification of flavonoids using macroporous polymer resin. The key findings of this review reveal that macroporous resins with weak polarity, large surface areas, and pore diameters have a stronger adsorption capacity for flavonoids compared to polar resins. Furthermore, ultrasonic-solvent assisted extraction often combines with macroporous resin for effective the extraction and purification of flavonoids.

A review with updated perspectives on in vitro and in vivo wound healing models.

A skin wound or perforation triggers a series of homeostatic reactions to safeguard internal organs from invasion by pathogens or other substances that could damage body tissues. An injury may occasionally heal quickly, leading to the closure of the skin's structure. Healing from chronic wounds takes a long time. Although many treatment options are available to manage wound healing, an unmet therapy need remains because of the complexity of the processes and the other factors involved. It is crucial to conduct consistent research on novel therapeutic approaches to find an effective healing agent. Therefore, this work aims to cover various in vitro and in vivo methodologies that could be utilised to examine wound recovery. Before deciding on the optimal course of action, several techniques' benefits, drawbacks, and factors need to be reviewed.
