Over the last few decades, a growing body of evidence has increasingly showed the therapeutic capabilities of ''[[Cannabis]]'' plants.

The accumulation of these metabolites in the flower is versatile and influenced by a largely unknown regulation system, attributed to genetic, developmental, and environmental factors. As ''Cannabis'' is a [[Dioecy|dioecious]] plant, one main factor is fertilization after successful pollination.

[[Terpene]]s are the primary constituents of essential oils and are responsible for the aroma characteristics of the ''[[Cannabis]]'' plant. Together with [[cannabinoid]]s, terpenes illustrate a potential synergic and/or [[entourage effect]], with their interactions having only been speculated on for the last few decades. Hundreds of terpenes have been identified that additionally add to the overall cannabis sensory experience, contributing largely to the consumer’s experiences, as well as the market price.

"Quality control of cannabis inflorescence and oil products: Response factors for the cost-efficient determination of ten cannabinoids by HPLC"

The quality control (QC) of medicinal cannabis should include quantification of as many cannabinoids as practicable in a routine analytical laboratory, to accurately reflect the quality of the product. However, the cost and availability of some cannabinoid standards is an impediment to their routine use. This work seeks to overcome this obstacle by analyzing samples using relative retention times (RRT) and relative response factors (RRF), relative to cannabidiol (CBD) and cannabidiolic acid (CBDA) reference standards which are readily available. A high-performance liquid chromatography-photodiode array (HPLC-PDA) method was developed to quantify 10 cannabinoids ... (Full article...)
