To date, approximately 500 natural constituents of hemp (Latin name: cannabis sativa L.) have been discovered. Most of these chemicals are also found in many other plants and animals, although their pharmacological effects are generally weak or non-existent. Among the elements that make up the cannabis plant are amino acids, proteins (albumin), sugars, terpenes, cannabinoids, flavonoids, vitamins, hydrocarbons, alkaloids, aldehydes, ketones, acids fat, pigments and many other families of substances. Nearly 120 of these compounds belong to the terpene family alone, more commonly known as essential oils. Each plant, taken individually, contains only part of all of these 500 natural molecules, in particular depending on its variety. The basic structural scheme of perrottetitenic acid, whose pharmacological effects on humans are not yet known, is very similar to that of delta-9-THC. To date, approximately 75 types of cannabinoids have been identified.
