Flavonoids belong to the comprehensive category of polyphenols and namely flavon-3-ols (flavonols, anthocyanins, isoflavones, flavanones and flavones) are found in plant sources. Quercetin, rutin and silibinin exhibit numerous pharmacological spectrum but it has hurdles like poor aqueous solubility, rapid clearance and poor penetration potential attribute to reduced clinical usage. Hence the aim of this research is to design and evaluate of antimicrobial and wound healing activities of dual loaded flavones nano formulations scaffold with chitosan-based film by nanopreception techniques. The prepared film was subjected characterization studies such as physical appearance, thickness, weight variation, folding endurance and water absorption capacity in addition was to evaluate anti-microbial activity of dual loaded flavones nano formulation film by well diffusion method and skin irritation study performed as per OECD 406 guide lines. The prepared duo loaded flavonol scaffold chitosan film employed with in-vivo wound healing activity in excision wound model. Results revealed that chitosan film scaffold with quercetin and rutin nano formulations and film scaffold with quercetin and silibinin nano formulations showed significant zone of inhibition when compared with control group. Acute skin irritation study revealed that the film scaffold with quercetin and rutin nano formulations and film scaffold with quercetin and silibinin nano formulations shows no adverse event such erythema and skin irritation. It was further found that all three groups showed decreasing of wound area from day to day. However, on 14th day, control group showed 75.91% wound healing, whereas the quercetin and silibinin group showed 84.75% wound healing. On the other hand, Quercetin and Rutin Group showed appreciable wound healing activity of 90.70%. Hence Chitosan scaffold film with quercetin and rutin nano formulations has enhanced wound healing and re-epitheliasation activity.
