Inventors include Dr. Darapu Uma; Mrs. P Gayathri; Mr. Krishna Chaitanya Pidugu; and Dr. Balla Satyanarayana.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The present invention relates to a biodegradable wound dressing containing plant-derived bioactive compounds for promoting wound protection, antimicrobial activity and tissue regeneration. The wound dressing comprises a biodegradable polymeric matrix incorporated with one or more plant-derived bioactive components having antimicrobial, antioxidant and/or woundhealing properties. The biodegradable matrix may comprise chitosan, alginate, cellulose derivatives, gelatin, collagen, starch, pectin, hyaluronic acid or combinations thereof. The plant bioactive component may comprise phenolic compounds, flavonoids, tannins, terpenoids, essential oils, alkaloids or other phytoconstituents obtained from medicinal plants or plant-derived materials. In one embodiment, the plant bioactive is incorporated as a plant extract, enriched fraction, nanoencapsulated bioactive or nanoemulsion to improve stability and controlled release. The dressing is configured to provide a moist and protective environment at the wound site while gradually releasing the incorporated bioactive compounds. The composition may exhibit antimicrobial activity against wound- associated microorganisms, antioxidant activity and support for cellular proliferation and tissue regeneration. The biodegradable dressing may be provided as a film, membrane, hydrogel, sponge, nanofibrous mat or composite dressing and may be applied to acute, superficial or chronic wounds. The invention provides a biodegradable and plant-based wound dressing that combines physical wound protection with sustained delivery of natural bioactive compounds, thereby providing an alternative to conventional wound dressing materials.
