title: Conventional and modified hydrodistillation method for the extraction of glucosinolate hydrolytic products: a comparative account.
abstract: Eruca sativa is extensively used as raw and its oil is also used for cooking due to its exceptional flavour. The volatile nature of the hydrolytic products of glucosinolates makes the extraction difficult. The hydrodistillation method used previously yield very less amount of the extract as well as the absence of stirring in the round bottom flask causes burning of both the crushed seeds and the flask. To overcome these drawbacks, a method has been developed using magnetic stirrer and hot plate. The yield and composition of hydrolytic products in the extract with the modified method was increased along with an increase in the amount of major hydrolytic products as seen by GC-MS. This method thus has immense potential in pharmaceutical industries, due to the ease of extraction and isolation.
