Dr. Jacqueline von Salm
Dr. Jacqueline von Salm will present her talk titled “Unique Terpene Metabolites as Descriptors of Cannabis Phenotypes and Products” at 10:48 a.m. (EDT) on Wednesday, May 6 during the Spring 2020 CANN Virtual Symposium in The Second Annual ElSohly Award session. Sign up for free today.
What will your talk at the CANN symposium focus on?
Dr. Jacqueline von Salm: The talk will be focused on terpene metabolomics of our in-house cultivars and which terpenes best describe the differences or similarities between phenotypes. Other groups have also done this research, but as with any chemical ecology type studies, environment is so important for chemical production. Our chemovars show a specific terpene that has largely been ignored in cannabis is a major differentiator among phenotypes. This terpene isn’t even regularly tested by third party labs!

Jiries Meehan-Atrash
Jiries Meehan-Atrash will present his talk titled “Thermal Degradation of Cannabis Extract Constituents: Mechanistic Insight” at 11:15 a.m. (EDT) on Wednesday, May 6 during the Spring 2020 CANN Virtual Symposium in The Second Annual ElSohly Award session. Sign up for free today.
What will your talk at the CANN symposium focus on?
Jiries Meehan-Atrash: My talk at the CANN symposium deals with some experiments I performed recently that were one of the first times that isotopic tracing was used to study the degradation chemistry happening in e-cigarettes, and certainly the first time it’s been applied to cannabis vapes. The Strongin group is one of the few that studies the degradation of e-cigarette components mechanistically, looking at the bigger picture to help guide future efforts. Specifically, what we did here was mix THC with deuterated myrcene and limonene, then subject this mixture to dabbing and looked at what sorts of deuterated degradation products resulted. What we found was fascinating. From previous studies we knew that, unsurprisingly, dabbing pure terpenes produces very high levels of isoprene, and we theorized that other degradation products such as methacrolein and methyl vinyl ketone result from the oxidation of isoprene. Dabbing pure THC produces a similar slew of toxic degradants, which was a new discovery, and adding terpenes appears to increase the levels, but how? Dabbing the myrcene-d6/THC mix produced elevated levels of deuterated isoprene-d5, methacrolein-d5 and methyl vinyl ketone-d3, and a higher myrcene-d6/THC ratio produced more deuterated degradants. The pattern of deuterium incorporation matches previously described mechanisms for free radical degradation of isoprene in the atmosphere; the fact that the same mechanism for this happens in dabbing is completely fascinating.

Dr. Markus Roggen
Dr. Markus Roggen will present his talk titled “Collaborative Research for Fundamental Insight into Cannabis Production” at 11:38 a.m. (EDT) on Wednesday, May 6 during the Spring 2020 CANN Virtual Symposium in The Second Annual ElSohly Award session. Sign up for free today.
What will your talk at the CANN symposium focus on?
Dr. Markus Roggen: As this CANN symposium is in recognition of the ElSohly award, my presentation will aim to validate this honor bestowed up on me. I will present a broad overview of the research in our laboratory at Complex Biotech Discovery Ventures. A large part of our current efforts is data analytics of cannabis extraction and the development of a predictive algorithm for extraction optimization. Although, I will also report on our continued quest to understand molecular changes in cannabis processing steps.

Dr. Sang-Hyuck Park
Dr. Sang-Hyuck Park will present his talk titled “Inhibitory Effects of Cannabidiol (CBD) on the Growth and Development of Tobacco Hornworm Manduca sexta” at 12:06 p.m. (EDT) on Wednesday, May 6 during the Spring 2020 CANN Virtual Symposium in The Second Annual ElSohly Award session. Sign up for free today.
What will your talk at the CANN symposium focus on?
Dr. Sang-Hyuck Park: Cannabidiol (CBD) has recently been garnering a great deal of global attention in part because of its potential therapeutic uses in human disorders. Despite the increased interests in CBD, little has been known about the evolutionary role that this might have conferred to cannabis plants. For my talk at the CANN symposium, I will primarily focus on the defensive role of CBD against the pest insect, tobacco hornworm Manduca sexta, and how CBD deters the insect feeding behavior as well as inhibiting their growth and development.
