ANTIOXIDANT POTENTIAL, TOTAL PHENOLIC AND FLAVONOID CONTENT OF ROOTS OF SEVEN ASPARAGUS SPECIES FROM NORTH-WEST INDIA
The aim of current study was to compare the total phenolic content (TPC), total flavonoid content (TFC) and antioxidant activity of roots of seven Asparagus species from North-West India. Total phenolic content measured by Folin-Ciocalteu method ranged from 3.85 ± 0.25 (A. racemosus) to 7.74 ± 0.03 (A. falcatus), 3.42 ± 0.14 (A. racemosus) to 7.22 ± 0.12 (A. falcatus) and 1.12 ± 0.13 (A. offi...

VALIDATED STABILITY INDICATING HPTLC METHOD FOR PROTOCATECHUIC ACID
Protocatechuic acid (PCA) is a type of widely distributed naturally occurring phenolic acid, commonly found in bran, grain, brown rice, fruits such as plums, gooseberries, grapes and also in onion peels. A new, simple, precise, accurate and sensitive stability-indicating HPTLC method for Protocatechuic acid was successfully developed. This method is based on HPTLC separation followed by UV detecti...

UV-SPECTROPHOTOMETRIC METHOD FOR SIMULTANEOUS ESTIMATION OF LORNOXICAM AND EPERISONE HYDROCHLORIDE IN BULK DRUG, FORMULATIONS AND AQUEOUS DISSOLUTION SAMPLES
Lornoxicam has been found to be not interacted by eperisone hydrochloride at 377 nm. Therefore, it is estimated directly as a single component in the mixture, whereas eperisone hydrochloride is throughout interfered with by lornoxicam in UV region. So, it was estimated in the mixture using a two-wavelength difference method. Lornoxicam was found to have same absorbance at 262 nm and 283 nm but not...

A FACILE NOVEL SYNTHESIS OF ThO2/Fe3O4 NANOCOMPOSITE WITH ENHANCED PHOTOCATALYTIC ACTIVITY FOR THE DEGRADATION OF MALACHITE GREEN UNDER VISIBLE LIGHT IRRADIATION
An innovative magnetically separable ThO2/Fe3O4 nanocomposite was successfully synthesized by hydrothermal method. The synthesized ThO2/Fe3O4 nanocomposite was characterized by UV-DRS, FT-IR, XRD, HR-TEM, BET, and TGA techniques. XRD and HR-TEM images displayed the overall spherical shape and confirmed the formation of well crystalline ThO2/Fe3O4 nanocomposite. The catalytic efficiency of ThO2/Fe3...
