Abstract:
Five new metabolites, including two monoterpene glycosides Pubescenosides L-M (1-2) and three phenolic glycosides, Pubescenosides N-P (3-5), along with nineteen known ones, including liganoids, hemiterpenoids and caffeoylquinic acid derivates, were isolated from the roots of Ilex pubescens. Their structures were elucidated from extensive spectroscopic analysis, including 1D and 2D NMR experiments. This study is the first to report monoterpene glycosides with β-pinene aglycone in Aquifoliaceae. Nine of these compounds were evaluated in vitro for their anti-platelet aggregation activities. Among them, compounds 3 and 4 showed moderate inhibitory activities on ADP-induced blood platelet aggregation [inhibition (%): 32.3 and 33.6, respectively] as compared to aspirin.

Oxidation of Phenols to Quinones
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox...
Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and...
