Abstract
BACKGROUND Astaxanthin (AST) is approved by the US Food and Drug Administration (FDA) as a safe dietary supplement for humans. As a potent lipid-soluble keto-carotenoid, it is widely used in food, cosmetics, and the pharmaceutical industry. However, its low solubility limits its powerful biological activity and its application in these fields. This study aims to develop a delivery system to address the low solubility and bioavailability of AST and to enhance its antioxidant capacity. RESULTS Astaxanthin-loaded composite micelles were successfully prepared via coaxial electrospray technology. Astaxanthin existed in the amorphous state in the electro-sprayed formulation with an approximate particle size of 186.28 nm and with a polydispersity index of 0.243. In this delivery system, Soluplus and copovidone (PVPVA 64) were the main polymeric matrix for AST, which then released the drug upon contact with aqueous media, resulting in an overall increase in drug solubility and a release rate of 94.08%. Meanwhile, lecithin, and Polyethylene glycol-grafted Chitosan (PEG-g-CS) could support the absorption of AST in the gastrointestinal tract, assisting transmembrane transport. The relative bioavailability reached about 308.33% and the reactive oxygen species (ROS) scavenging efficiency of the formulation was 44.10%, which was 1.57 times higher than that of free astaxanthin (28.10%) when both were at the same concentration level based on astaxanthin. CONCLUSION Coaxial electrospray could be applied to prepare a composite micelles system for the delivery of poorly water-soluble active ingredients in functional food, cosmetics, and medicine. © 2023 Society of Chemical Industry.

Enhanced oral bioavailability of capsaicin-loaded microencapsulation complex via electrospray technology: Preparation, in vitro and in vivo evaluation. Biopharm Drug Dispos 2023; 44:137-146.

Abstract
The purpose of this work was to fabricate the microencapsulation of capsaicin using electrospray technology and polyvinylpyrrolidone (PVP) K30 as a carrier. The morphological characteristics of capsaicin-PVP electrosprayed microencapsulation complex under different processing parameters were observed by scanning electron microscope (SEM), while the best process was determined, wherein it comprised of 10 KV (voltage), 0.8 ml·h-1 (solution flow rate), 0.9 mm (the inner diameter of the needle), and 10 cm (receiving distance). The X-ray diffraction results of the electrosprayed complex showed that capsaicin was present in the carrier in an amorphous form. The drug release properties of capsaicin powder and electrosprayed complex in different media were investigated. The results showed that in vitro release rates of the capsaicin complex in different media were much higher than that of capsaicin powder, with correspondingly improved bioavailability, defined by intravenous and oral dosing in rats in vivo, for the electrosprayed complex compared to that of capsacin powder. The dose absorbed of the electrosprayed complex was 2.2-fold that of the capsaicin powder. In short, electrospray technology can be used to prepare capsaicin-loaded electrosprayed microencapsulation complex. This technique can improve the solubility and bioavailability of capsaicin, and provide a new idea for the solubilization of other insoluble drugs.
