Abstract

Hardwoods are a class of tree that holds multiple types of extractives, some of which have their own specialized biological activity. Characterizing these compounds in greater depth can help virologists understand how natural chemicals are able to resist infection, leading to pharmaceutical uses. Hardwoods are known to contain high concentrations of different phenolic compounds which exhibit anti-microbial properties. Liquid-liquid fractionation was used to separate extracts with the same polar characteristics in different solvents. GC/MS spectra showed Black Locust, Catalpa, & Honey Mesquite, had a number of potential biological-active phenolic compounds despite differences in durability.
