Optimized Extraction of Oleoresin Capsicum and Analytical Method Validation for Capsaicin using HPLC

Optimized Method for Curcumin Separation from Turmeric Oleoresin

In this work, a novel and modified method for the solvent purification of Curcumin is presented, a composite of normal hexane & 2-propanol solvents was used to separate the fat content and other impurities. The process was modeled considering the response surface methodology as described by the central composite design. The adjusted R-squared was 0.9443 indicating the variation betwe...

Paprika (Capsicum annuum) oleoresin extraction with supercritical carbon dioxide.

Paprika oleoresin was fractionated by extraction with supercritical carbon dioxide (SCF-CO(2)). Higher extraction volumes, increasing extraction pressures, and similarly, the use of cosolvents such as 1% ethanol or acetone resulted in higher pigment yields. Within the 2000-7000 psi range, total oleoresin yield always approached 100%. Pigments isolated at lower pressures consisted almost exclusi...

Analytical Method Development and Validation of Estimation Method for Sotalol Hydrochloride Tablets by Using Rp-hplc

The present investigation describes about a simple, economic, selective, accurate, precise Reverse phase High performance liquid chromatographic method for the estimation of Sotalol Hydrochloride in pharmaceutical dosage forms. Sotalol Hydrochloride was well eluted using a C18 column of dimension 100 × 4.6, 5μm and Mobile phase consisting of Acetonitrile: 20 mM Ammonium acetate buffer (pH-6): M...
