Ultrasound-Assisted Extraction of Micro- and Macroelements in Fruit Peel Powder Mineral Supplement for Osteoporosis Patients and Their Determination by Flame Atomic Absorption Spectrometry

Osteoporosis is a worldwide disease depicted by the reduced bone mass, an adequate supply of minerals needed to support remodeling, and their deficiency causes bone-related diseases, osteoporosis in particular, has osteoprotective effects. The aim this recent research was quantify micro- (Mn, Fe, Cu, Zn) macroelements (Mg, K, Ca) peel powder some common fruits (pomegranate, orange, lemon, mango, grapefruit) flame atomic absorption spectrometer (FAAS). extraction done using dilute acids ultrasonic bath. Apple leaves were used as standard reference material (SRM, NIST 1515) optimize ultrasound-assisted (UAE) method at varied operating parameters. Maximum response obtained for extracting 500 mg SRM 60°C temperature, setting vortexing time 5 min while 5.0 mL agent HNO3 (0.5 M)-H2O2 (10%) 90% sonication amplitude ultrasound bath 6 min. While analyzing SRM, percentage recovery range between 96.8 102.7% assure accuracy whereas repeatability (n = 10) study terms % RSD yielding ?2.29 supports well precision proposed method, limits quantitation (?g/g) 0.034, 0.061, 0.065, 0.057, 0.017, 0.175, 0.053 Mn, Zn, Mg, Ca, respectively. UAE reliable, efficient, advantageous over conventionally employed acid digestion with regard less consumption reagents short analysis determination fruit powder.
