Ultrasonic Assisted Extraction of Natural Pigments from Rhizomes of Curcuma Longa L.
Ultrasound-assisted extraction (UAE) was evaluated as a simpler and more effective alternative to conventional extraction methods for the isolation of curcuminoids from turmeric plant rhizomes. The turmeric samples were extracted under indirect sonication in an ultrasonic bath, and compared with the conventional methods. It was found that the yield of ultrasound-assisted extraction was approxim...
متن کاملNew withanolides with TRAIL-sensitizing effect from Physalis pubescens L.
Physalis pubescens L. plant produces nutritious and healthy fruits, called husk tomato or hairy ground cherry. However, its bioactive components are largely unknown. Four new withanolide steroids (1-4) together with one known withanolide (5) were isolated from the extract of P. pubescens L. and their chemical structures were established by extensive spectroscopic analyses. Compounds 1, 3 and 5 ...
