Okanin 4'- O-beta- D-(2'',4'',6''-triacetyl)-glucoside, okanin 4'- O-beta- D-(6''- TRANS-P-coumaroyl)-glucoside, both new natural compounds, and okanin 3'- O-beta- D-glucoside have been isolated from the leaves of BIDENS PILOSA L. Their structures have been elucidated by means of UV, FD-MS, (1)H-NMR, and (13)C-NMR spectroscopy. NMR spectral data for okanin(More)
Three new acylated chalcone glucosides [okanin 4'- O-beta- D-(4''-acetyl-6''- TRANS- P-coumaroyl)-glucoside, okanin 4'- O-beta- D-(2'',4''-diacetyl-6''- TRANS- P-coumaroyl)-glucoside, and okanin 4'- O-beta- D-(3'',4''-diacetyl-6''- TRANS- P-coumaroyl)-glucoside] have been isolated from the leaves of BIDENS PILOSA L. (Asteraceae). Their structures have been(More)
The purpose of this work was to assess the use of food colors as a visual aid to determine homogeneous mixing in the extemporaneous preparation of capsules. Six different batches of progesterone slow-release 200-mg capsules were prepared by different mixing methods until visually determined as homogeneous based on yellow food coloring distribution in the(More)
