Simultaneous Quantitation of Boric Acid and Calcium Fructoborate in Dietary Supplements by HPTLC–Densitometry

摘要: The paper describes a new, simple, selective and precise high-performance thin-layer chromatographic (HPTLC) method for the simultaneous identification quantitative determination of boric acid (BA) calcium fructoborate (CFB) in bulk tablet/capsule dosage forms dietary supplements. HPTLC silica gel G 60 F254 precoated glass plates were used as stationary phase. mobile phase consisted 2-propanol-water 8:2 (v/v). two boron-based compounds adequately separated with Rf values 0.83 ± 0.01 0.59 (CFB).
