Abstract:
The present invention relates to a process for separation of oxyresveratrol molecule from the extracted solution of Artocarpus lakoocha Roxb. through membrane application. The product can be obtained in excellent yield upto 81% in case of extraction using water as solvent and can be separated from the extracted mixture upto 98% using indigenously developed nanofiltration membrane. Only the desired Trans isomer is obtained and no cis isomerization takes place during the extraction process.
