Abstract: Cannabis sativa L. has been used as medicine for thousands of years. Since the early identification of
tetrahydrocannabinol (THC) in 1960, pharmacological activities were attributed to a group of unique structures
named cannabinoids. For decades, research and development were applied to determine different cannabinoids
and their medicinal properties. Nowadays there is evidence that the therapeutic benefits of the plant are based
on the synergy of cannabinoids and other secondary metabolites such as terpenes and flavonoids. Differences
between the medical performance of isolated compounds like cannabidiol (CBD) or THC and full-spectrum
plant extracts are notable. Indeed, the superiority of the last one is provoked by the synergy between various
different compounds. This improved medicinal effect is called the entourage effect. Chromatography has become
the method of choice for the determination of cannabinoids, terpenes, and flavonoids, so it represents an
excellent tool for a proper characterization of the plant and plant derived products. The objective of characterization
relies not only in analyzing the fingerprint of cannabis, but also to identify different chemotypes for medical
purposes. To understand the contributions of each natural product to this “entourage effect”, this review
presents an in-depth analysis of the utilization of High-performance liquid chromatography (HPLC), Gas chromatography
(GC) and other methods for the analysis of phytocomponents of Cannabis sativa L. In this sense, a
representative number of examples and advances made in the field together with limitations and future needs
are provided. It can be concluded that standardized protocols and quality control policies and procedures are
necessary for the comprehensive analysis of cannabis extracts and derivatives.
