Resveratrol, a naturally occurring polyphenolic compound, is widely recognized for its health-promoting properties. In this study, the resveratrol content of fresh grapes and grape pomace was determined using HPLC with external standard calibration. The calibration curve exhibited excellent linearity (Y = 1.98582 × 10⁻⁵X – 0.3297, R² = 0.9997, R = 0.9998), confirming the reliability of the method. Chromatographic analysis revealed a sharp peak at a retention time of 1.528 min for fresh V. labrusca samples, corresponding to a concentration of 282.6 ppm resveratrol (99.88% area). In V. labrusca pomace, resveratrol was also detected at a similar retention time (1.531 min), but with a lower concentration of 89.0 ppm (99.62% area). These results indicate that while fresh V. labrusca are a richer source of resveratrol, V. labrusca pomace still retains a substantial and noteworthy concentration of this bioactive compound. Rather than being treated merely as an industrial waste, V. labrusca pomace should be considered a sustainable and economically valuable reservoir of resveratrol, offering opportunities for high-value utilization. Its incorporation into nutraceutical, cosmetic, and pharmaceutical applications could not only enhance product functionality but also contribute to circular economy practices and environmental sustainability
