Potato peel represents a major by-product of the potato-processing industry and promising source bioactive compounds with potential health benefits. This study investigates biochemical nutritional composition peels from five purple two red potato cultivars, particular attention to their phytochemical profiles antioxidant properties. Total phenolic content, carbohydrates, proteins, lipids were quantified using UV-visible spectrophotometry. The was further characterized via High-Performance Liquid Chromatography coupled Diode-Array Detector (HPLC-DAD). Antioxidant radical-scavenging capacities extracts assessed through Ferric Reducing Power (FRAP) 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays. Significant variability observed across cultivars for all measured parameters. While samples rich in carbohydrates they shared common profile dominated by chlorogenic acid its derivatives, as well caffeic acid. Anthocyanin composition, however, highly cultivar-specific. Notably, demonstrated strong antiradical activities, agreement high total content. These findings highlight valuable sources functional ingredients food nutraceutical applications.

Sambucus javanica subsp. (SJ) has been used in traditional medicine the northern region of Thailand for healing bone fractures; however, studies on how this plant stimulates formation are still scarce. The present study aimed to investigate potential crude extracts and fractions obtained from SJ leaves osteoporotic protection. All samples were investigated murine preosteoblast MC3T3-E1 cells resorption biomarkers, namely alkaline phosphatase (ALP), osteocalcin (OC), osteoprotegerin (OPG), receptor activator nuclear factor-κB ligand (RANKL), OPG/RANKL ratio. Additionally, calcium deposits determined using alizarin red S staining technique. results indicated that water ethanol contained gallic acid, rutin, chlorogenic acid as major compounds. stimulated osteoblastic cell differentiation enhanced osteoprotective activity, measured by a significant increase ALP OC, OPG, ratio, degree calcification. they exhibited negative impact significantly reducing RANKL reactive oxygen species (ROS) production. Therefore, our findings add novel evidence indicating extraction could be further utilized natural active pharmaceutical ingredient (NAPI) development health products.
