"Analysis of cannabidiol, delta-9-tetrahydrocannabinol, and their acids in CBD/hemp oil products"

Hemp products are readily available and are aggressively marketed for their health and medicinal benefits. Most consumers of these products are interested because of their cannabidiol (CBD) content, which has taken the natural products industry by storm. The CBD and delta-9-tetrahydrocannabinol (delta-9-THC) concentrations in these products are often absent, and even where labeled, the accuracy of the label amounts is often questionable. In order to gain a better understanding of the CBD content, fifty hemp products were analyzed by gas chromatography coupled with mass spectrometry (GC-MS) for CBD, delta-9-THC, tetrahydrocannabinolic acid (delta-9-THCAA), and cannabidiolic acid (CBDA). Delta-9-THCAA and CBDA are the natural precursors of delta-9-THC and CBD in the plant material. (Full article...)
