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

Vinayagam A, Sudha PN - Indian J Pharm Sci (2015 Jan-Feb)

Bottom Line: 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 Nerium indicum flowers were confirmed by Mass, HPLC and UV.The structures of these compounds confirmed with the help of liquid chromatography mass spectrometry.

ABSTRACT
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 Nerium indicum flowers were confirmed by Mass, HPLC and UV. The structures of these compounds confirmed with the help of liquid chromatography mass spectrometry.

Figure 7: Structure of flavonoids.a. quercetin-3-O-rutinoside, b. luteolin-5-O-rutinoside, c. luteolin- 7-O-rutinoside.

Mentions: Based on the above data two phenolic acids, trans 5-O-caffeoylquinic acid and cis 5-O-caffeoylquinic acid (fig. 6). Three flavonoid glycosides, quercetin-3-O-rutinoside, luteolin-5-O-rutinoside and luteolin-7-O-rutinoside (fig. 7) were identified from crude methanolic extract of Nerium indicum flowers.
