analyses of ancient cannabis from Central Asia
Snubblade över en fruktansvärt intressant artikel, där uråldrig cannabis i en gravplats analyseras.
Borde en gång för alla döda myten om att cannabis skulle blivigt starkare och farligare de senaste åren med tanke på att alla fakta alltså tyder på att redan för 2700 år sedan så odlade de plantan medvetet, samlade endast sensimillan från honblommorna, och kemiska analysen visar att denna sort var hög thc halt och låg cbd redan då…
The results presented collectively point to the most probable conclusion which is that the G?sh? culture cultivated cannabis for pharmaceutical, psychoactive or divinatory purposes. In examining the botanical evidence from this ‘old and cold’ site with its unique degree of preservation, the cannabis consisted of a processed (pounded) sample whose seed size, colour, and morphology, at least according to principles of Vavilov (Vavilov, 1926), suggest that it was cultivated rather than merely gathered from wild plants. The considerable amount of cannabis present (789 g) without any large stalks or branches would logically imply a pooled collection rather than one from a single plant. Importantly, no obvious male cannabis plant parts (e.g. staminate flowers, not infrequently observed in Indian herbal cannabis, or bhang (Russo, 2007) were evident, implying their exclusion or possible removal by human intervention, as these are pharmacologically less psychoactive.
The HPLC, GC, and MS analyses confirm the identity of the supplied plant sample as Cannabis sativa L. The predominance of CBN indicates that the original plants contained ?9-tetrahydrocannabinol (THC) as the major phytocannabinoid constituent. The presence of CBO and numerous CBN-related substance peaks further supports this view. CBD and CBC, together with their known thermo-oxidative degradation products CBE and CBL (Brenneisen, 2007), are present, but the GC analysis would appear to indicate that, in both cases, CBC and CBL are represented in greater quantities, as expected in a high-THC cannabis strain wherein CBD is only a minor component. In addition, there is a peak for CBNV which confirms that the plant also contained ?9-tetrahydrocannabivarin (THCV), a propyl phytocannabinoid. All of these observations are consistent with strains of cannabis with a high THC content and in an alternative taxonomy suggests it should be assigned to Cannabis indica Lamarck (Hillig and Mahlberg, 2004).
