Crude Drugs



Classic drugs are based on natural products: e.g. on leaves, flowers, roots or fruits of plants, on secretions from small animals or insects. Proven effectiveness and many years of experience make them interesting to this day. Ingredients, pharmacological agents and their interactions are the subject of extensive analytical work.

The Determination of CBD and General Cannabinoid Content in Hemp Oils Using HPLC with UV Detection

Medical marijuana generally possesses high levels of the psychotropic tetrahydrocannabinol, d9-THC and lower levels of the non-psychotropic cannabidiol, CBD. Pain mitigation and reduced severity of nausea and seizures are just a few of the therapeutic benefits reported by medical cannabis patients. Little has been done to better understand the chemistry of benefits from CBD. To complicate matters, there is evidence that a combination of CBD, a host of other minor cannabinoids and a complex array of terpenoids may be the most beneficial – called the “entourage effect”.  CBD-rich oil has become increasingly popular and is administered via sublingual drops, gel capsules or as topical ointment.



Technical Report – Characterization of the volatile fraction of Brazilian essential oil, namely Cordia verbanaceae

Essential oil of a Brazilian medical plant, Cordia verbenaceae L., was characterized by means of GC-MS technique. The volatile compounds were identified using the FFNSC MS library, a flavor and fragrance database with embedded linear retention index (LRI). Using two simultaneous filters, namely ≥ 90% MS similarity and +/- 5 LRI, 48 individual molecules were identified, providing a very fast and reliable peak assignment in the identification process.
