Invitro Determination of Flavonoids and Phenolic Compounds from Corm of Amorphophallus Campanulatus (Roxb.)

Introduction

Today attention has been focused on such species which have reactive oxygens and free radicals are which play vital role in the genesis of varied diseases which are imflammation, cataract, liver cirrliosis, reperfusion injury, cancer and others (Halliwel et.al., 1994). The herbal drugs have such phytoconstituents are the gaining importance in the prevention and treatment of various organ toxicities due to xenobiotic challenges or environmental challenges. A. campanulatus (RoxB.) from family Araceae a tuberous, stout indigenous herb commonly known as elephant foot yam, suran, grown as vegetable is widely available (Ghani A.; 1998) and is reported to contain flavonoids (Shilpi J.A., et.al., 2005). In Ayurvedic System of Medicine, tubers of A. campanulatus (RoxB.) has been indicated in treating various above mentioned patho-physiological conditions due to Rective oxygens species (ROS) (Narayana Das Prajapati, et.al., 2004; Sivaraj V.V., 1994; Kirtikar K.R. et.al., 1987; Nadkarni K. M. et.al., 2000; Guha Bakshi D.N. et.al., 1999; Pullilah T., 2000). Tubers are reported in management of haemmrroids (Vastrad C.S., et.al) to have antiprotease activity (Pratibha S., et.al., 1995), antimicrobial activity (Alam Khan. et.al., 2008) and analgesic activity of its methanolic extract (Shilpi J. A. et.al., 2005). This exhaustive literature survey revealed that the tubers (corm) are not yet screened for its quantitative evaluation of Flavonoids and Total Phenolic contents of the extracts of the corm. Hence in the present study an attempt is made to standardize the corm of A. campanulatus (RoxB.) in terms of its Flavonoidal content and Total Phenolic content References 1.
