Determination of total flavonoids in various developmental stages of an ethno medicinal plant Caesalpinia bonducella (L.) Roxb.

Caesalpinia bonducella (L.) Roxb. is a perrinial prickly climber belonging to the family Caesalpniaceae. The present study deals with the preliminary phytochemical analysis and determination of total flavonoid content in various developmental stages of Caesalpinia bonducella by Aluminum chloride colorimetric method .The total flavonoid content of seedlings of 30 ,60,90 and 120 days and the entire shoot of plant before flowering ,at flowering and after flowering were found to be 2.6µg, 0.9 µg, 0.3 µg,0.2 µg ,0.4 µg,0.6 µg and 1.6 µg respectively. This study reveals the suitable developmental stages to be used for the extraction of flavonoids which imparts many pharmacological activities of the plant.
