11-beta-Hydroxy-D: A friedoolean-1-1-en-3-one from the stem bark of Phyllanthus flexuosus

, : 11-beta-Hydroxy-D: A friedoolean-1-1-en-3-one from the stem bark of Phyllanthus flexuosus. Journal of Natural Products (Lloydia) 57(11): 1523-1528

A new pentacyclic triterpene ketol was isolated from the stem bark of Phyllanthus flexuosus and the structure was established on the basis of spectral data interpretation and single-crystal X-ray analysis as 11-beta-hydroxy-D: A-friedoolean-1-en-3-one bearing a stretched conformation of the cis-fused D and E rings.

The error arising when evaluating FHR [fetal heart rate] variability on CTG [cardiotocographic] curves is demonstrated. Visual estimation is based on the appreciation of oscillation amplitude (O. A.) which is necessarily dependent on basic heart f...

The high Glc signalling interacts positively with ABA, but negatively wit...
