This research work will highlight the potential of soy protein isolate (SPI) to enhance the solubility and rapid dissolution of hydrophobic drugs like resveratrol. Resveratrol (RES) has multiple therapeutic effects including antioxidant, cardioprotective, anti-inflammatory and anticancer activity, however these are limited by the drugs poor aqueous solubility and stability. One good candidate for drug solubility enhancement is SPI derived from soybeans and is used in the food industry due to its functional properties, non-toxic nature, low cost, easy availability and high nutritional values. Here, we report a simple rotavap method for nanoencapsulation of resveratrol into naturally occurring SPI. This would enhance its physicochemical properties including solubility and in-vitro dissolution, which will in turn improve its biological performance. Nano-encapsulated resveratrol was found to be in amorphous form and showed more than two times higher solubility with significantly rapid dissolution as compared to free resveratrol.1 This nanoencapsulation of resveratrol into SPI will boost the clinical effectiveness of RES and could be utilised for other poorly soluble hydrophobic drugs.
