Abstract:
Two benzoic acid allopyranosides, pseudolaroside A and pseudolaroside B, along with seven known compounds were isolated from the bark of Pseudolarix kaempferi. Their structures were determined by analysis of HR-ESI-MS, 1D and 2D NMR spectroscopic data, chemical analysis and comparison to the literature data.

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 phenols...
