Abstract

Bael [Aegle marmelos (L.) Correa], is well known in Indian traditional medical system for its multipurpose use in treatment of various diseases. Fresh ripe fruits are used in various types of shakes and sharbats but bael fruits are mainly used into its processed form like nectar or squash, jelly, candy and murabba. Bael powder is another form of product which has very high pharmaceutical value, long storability and is the pure concentrated form of fruit pulp. The aim of this study is to measure the nutraceutical values in bael powder (dry weight basis) prepared from fruit of CISH B-1 harvested at various stages of growth and development [180–335 days after fruit set (DAFS)] by using a simple HPLC technique and atomic absorption spectrophotometer (AAS). The antioxidants value (in terms of FRAP) ranges from 13.45 mmol/g at 180 DAFS (month of November) to 22.6 mmol/g at 335 DAFS (month of April). Maximum polyphenols content (5.99%) was observed at 305 and 335 DAFS (months of March and April). The antioxidants and polyphenols were enhanced significantly with the maturity of the fruits. Marmelosin and psoralen concentrations were highest at 215 DAFS and were found as 737 and 511 µg/g, respectively. Thereafter, both compounds declined significantly in mature fruit powder. Mineral contents in powder also varied with maturity stages. From this study, it may be concluded that powder prepared from immature fruits collected at early stages of development (November-January; 180–245 DAFS), possessed significantly higher amount of potassium, iron, marmelosin, psoralen and tannic acid, whereas, mature fruit powder (harvested during March-April; 305-335 DAFS) contains significantly higher content of zinc, copper, polyphenols and antioxidants
