In the current study, we investigated 2 species of the genus Rhodiola for the inhibition of alpha-amylase,alpha-glucosidase and angiotensin converting enzyme (ACE) inhibitory activity. Water extracts of Rhodiola crenulata had the highest alpha-amylase inhibitory activity (IC50,98.1 microg total phenolic /ml) followed by ethanol extract of R.crenulata (IC50, 120.9 microg total phenolic/ml) and e...

Abstract All parts of Thanakha ( Hesperethusa crenulata R.) have been used as traditional skin care herbal material in Myanmar. In this study, coumarins from H. R. bark were isolated through solvent extraction, systematic fractionation, and repeated column chromatography. Spectroscopic analyses using ESI–MS, 1D NMR (1H 13C), 2D (gHSQC gHMBC), specific rotation, circular dichroism, IR spectromet...

Waldeckia Chevreux is a genus of scavenging lysianassoid amphipods with distribution records from Antarctica, Australia, Thailand, Indonesia, Singapore, the Philippines, Vietnam, China and Japan. The genus is revised and diagnosed against all other genera of the Lysianassidae and the subfamily Waldeckiinae is established. All known species are redescribed and a key is provided. Three new specie...

Previously we have demonstrated that a Rhodiola crenulata extract (RCE), containing a potent antioxidant salidroside, promotes neurogenesis in the hippocampus of depressive rats. The current study was designed to further investigate the protective effect of the RCE on neurogenesis in a rat model of Alzheimer's disease (AD) induced by an intracerebroventricular injection of streptozotocin (STZ),...
