Abstract

Cannabinoids in hemp plant are strictly located in the inflorescence, in particular in top side of the plant while a lower amount may be found in the leaves. As a consequence, the lower amount of cannabinoids which can be recovered in the hemp flours is obtained from seeds, thus from contamination during harvesting procedures. To this aim, a screening test for the real time detection of cannabinoids in hemp flour was developed by a miniaturized analytical platform based on the MicroNIR spectrometer. Chemometrics was used to develop models of prediction to identify the cannabinoids and simultaneously to quantify the residual amounts in order to accomplish specific regulatory legislation according to the country. In particular, Partial Least Square-Discriminant Analysis (PLS-DA) and Partial Least Square regression (PLSr) were applied and results demonstrated that MicroNIR/Chemometric platform permit to differentiate hemp flours according to the presence of CBD, THC and CBG. In addition, for each cannabinoid, a quantification method was developed in the range 0.001-0.1 %ww, and their performances were evaluated by comparing results to those obtained by the reference procedures. Processing of the real samples provided a suitable correlation and confirmed the capabilities of this innovative platform to be used for the monitoring of the residual content of cannabinoids in hemp flours.

Hey, I’ve recently started using cbd gummy’s to help with my anxiety attacks, but I’ve noticed it doesn’t take effect fast enough to really help. I want to try out vaping it but I am not really interested in using disposables. Can you use any kind of pod systems to vape eliquid?

pre-made tincture are more expensive?

Republished by Plato

I’ve been looking around for tinctures, mainly full spectrum 1000mg/30 mL. The price for this has been hovering around $60-$70 from several vendors. However as I was browsing through powders, I found 1000mg full spectrum powder for just $30 at cbdistillery, at half the cost of pre-made full spectrum tincture. Is the price difference mainly just convenience? Pre-made tinctures seem to be far more expensive than a DIY. I understand you’d need to buy a carrier oil to make a tincture, so the total cost at first purchase would be more than $30, but one would be set for making additional cbd tinctures in the future.
