PHYSICAL EVALUATION AND QUALITATIVE CHEMICAL EXAMINATION OF FLOWERS EXTRACT OF NERIUM INDICUM.

Antioxidant Activity of Methanolic Extracts of Leaves and Flowers of Nerium Indicum

The Methanolic extract of leaves (LE) and Methanolic extract of flowers (FE) of Nerium indicum (Arali) was analysed for Antioxidant activity (AOA) in terms of DPPH free radicals, Total Phenolic Content (TPC) was measured in terms of Gallic acid equivalent and Flavonoid content was analysed in terms of Quercetin equivalent. The antioxidant activities of (LE & FE) were found to be 72.8% and 67 %....

Separation and Identification of Phenolic Acid and Flavonoids from Nerium indicum Flowers

Four major compounds were separated and identified from the methanol extracts of Nerium indicum flowers (Arali) using HPLC and mass spectral data. Through mass data, the chemical structures were elucidated as: trans5-O-caffeoylquinic acid (1), quercetin-3-O- rutinoside (2), luteolin-5-O-rutinoside (3) and luteolin-7-O-rutinoside (4). In addition, the cis isomers of 5-O-caffeoylquinic acid in Ne...
