HPTLC plates, Silica gel 60 RP-18

Description

• General description: 25 Glass plates 20 x 10 cm
• Application: Densitometric HPTLC method for qualitative, quantitative analysis and stability study of Coenzyme Q10 in pharmaceutical formulations utilizing normal and reversed-phase silica gel plates.: This study presents a high-performance thin-layer chromatography (HPTLC) method for analyzing Coenzyme Q10 in pharmaceutical formulations. The method employs both normal and reversed-phase silica gel plates to achieve qualitative and quantitative analysis, as well as stability testing of Coenzyme Q10 (Abdel-Kader et al., 2016).Simultaneous Quantification of Gymnemic Acid as Gymnemagenin and Charantin as β-Sitosterol Using Validated HPTLC Densitometric Method.: This research develops a validated HPTLC densitometric method for the simultaneous quantification of gymnemic acid and charantin in herbal formulations. The method utilizes silica gel 60 F₂₅₄ plates for effective separation and quantification (Ahamad et al., 2015).Estimation of catechin in Ayurvedic oil formulations containing Acacia catechu.: The study estimates the content of catechin in Ayurvedic oil formulations using HPTLC. Silica gel 60 F₂₅₄ plates are employed to ensure accurate quantification of catechin in these formulations (Dubey et al., 2009).Development and validation of HPTLC method for estimation of tacrolimus in formulations.: This paper details the development and validation of an HPTLC method for estimating tacrolimus in pharmaceutical formulations. The method uses silica gel 60 F₂₅₄ plates for efficient separation and quantification of tacrolimus (Borhade et al., 2009).Estimation of berberine in ayurvedic formulations containing Berberis aristata.: The research focuses on the estimation of berberine in Ayurvedic formulations. Using HPTLC with silica gel 60 F₂₅₄ plates, the study provides a reliable method for berberine quantification (Rout et al., 2008).
