Title: Constituents of Cannabis sativa, XXV. Isolation of two new dihydrostilbenes from a Panamanian variant.

Source: Journal of Natural Products
Date: 1984 May-Jun
Issue: 47(3)
Pages: 445-52

Two new dihydrostilbene compounds (named cannabistilbenes I and II) were isolated from a polar acidic fraction of a Panamanian variant of Cannabis sativa grown in Mississippi. The structure of cannabistilbene I was shown to be 3,4'-dihydroxy-5-methoxy-3'-(3-methylbut-2-enyl)-dihydrostilben e (1) from spectral data which was confirmed by synthesis. There is spectral evidence to indicate that cannabistilbene II could be represented by either structure 3 or 4.

Title: Constituents of Cannabis sativa L. XXII: isolation of spiro-indan and dihydrostilbene compounds from a Panamanian variant grown in Mississippi, United States of America.
Source: Bulletin on Narcotics
Date: 1982 Apr-Jun
Issue: 34(2)
Pages: 51-6
Abstract: Three spiro-compounds, namely cannabispiran, dehydrocannabispiran and beta-cannabispiranol, and 2 dihydrostilbenes [3-(2-(3-hydroxy-4-methoxyphenyl)ethyl)-5-methoxyphenol and canniprene] were isolated from a polar fraction of a Panamanian variant of Cannabis sativa L. grown in Mississippi, United States of America. The plant material was extracted with 95% ethanol and the dried ethanol extract was then partitioned between chloroform and water. The chloroform fraction was fractionated between hexane and 3N sodium hydroxide solution. Acidification of the basic fraction followed by extraction with ether afforded a polar acidic fraction from which the above-mentioned compounds were isolated through repeated chromatography. The structures of the above compounds were determined by spectral means as well as by comparison with reference samples. The isolation of two dihydrostilbenes and three spiro-indan compounds from a single variant provides good support that the dihydrostilbenes are the natural precursors to the spiro-indan compounds.

Title: Analysis and pharmacotoxicity of feruloyltyramine as a new constituent and p-coumaroyltyramine in Cannabis sativa L.
Source: Pharmacology, Biochemistry & Behavior
Date: 1991 Nov
Issue: 40(3)
Pages: 465-9
Abstract: Feruloyltyramine (FT), a new amide compound, together with p-coumaroyltyramine (p-CT) was isolated and identified in ethanol extract of cannabis seeds. FT and p-CT were also detected in the roots, leaves and resin of Cannabis sativa L. The intracerebroventricular injection of these amides caused hypothermia and motor incoordination in mice, and the maximal effects were caused 160 to 240 min after the injection. Furthermore, p-CT also exhibited cataleptogenic effect in mice, although FT did not show any effect. These results suggest that these amide compounds may be responsible for some pharmacotoxicity of marihuana.

Title: Influence of photoperiodism on cannabinoid content of Cannabis sativa L.
Source: Bulletin on Narcotics
Date: 1978 Jan-Mar
Issue: 30(1)
Pages: 67-8
Abstract:
Cannabis sativa plants submitted to 10 and 12 hours of natural light showed different content in cannabinoids. An increase of exposure to natural light of only 2 hours a day, at least, doubled the average amoung of THC, but decreased that of cannabichromene.

Title: Cannabiripsol: a novel Cannabis constituent.
Source: Experientia
Date: 1979 Oct 15
Issue: 35(10)
Pages: 1278-9
Abstract:
Cannabiripsol [(-) (6aR, 9S, 10S, 10aR)9,10-dihydroxy-hexahydrocannabinol] (1), a new cannabinoid was isolated from a South African Cannabis variant. The structure was determined by spectral means and by synthesis.

Title: (+/-)9,10-Dihydroxy-delta6a(10a)-tetrahydrocannabinol and (+/-)8,9-dihydroxy-delta6a(10a)-tetrahydrocannabinol: 2 new cannabinoids from Cannabis sativa L.
Source: Experientia
Date: 1978 Sep 15
Issue: 34(9)
Pages: 1127-8
Abstract:
The structures of 2 new polyhydroxylated cannabinoids, (+/-)9,10-dihydroxy-delta6a(10a)-tetrahydrocannabinol and (+/-)8,9-dihydroxy-delta6a(10a)-tetrahydrocannabinol, obtained from a hexane extract of an Indian Cannabis variant were determined by spectral means and correlation with cannabinol.

Title: Anhydrocannabisativine, a new alkaloid from Cannabis sativa L.
Source: Journal of Pharmaceutical Sciences
Date: 1978 Jan
Issue: 67(1)
Pages: 124
Abstract:
Ethanol extracts of the leaves and roots of a Mexican variant of Cannabis sativa L. (marijuana) afforded, after partitioning and chromatography, the new spermidine alkaloid, anhydrocannabisativine. The structure was determined by spectral analysis and semisynthesis.

Title: Structural studies of water-soluble glycoproteins from Cannabis sativa L.
Source: Carbohydrate Research
Date: 1977 Aug
Issue: 57
Pages: 135-44
Abstract:
Two carbohydrate-protein fractions, isolated from Cannabis sativa L. by extraction with water and chromatography of DEAE-cellulose, contained arabinose, galactose, glucose, mannose, galacturonic acid, 2-acetamido-2-deoxyglucose, and 2-acetamido-2-deoxygalactose. The structure of the carbohydrate moieties was investigated by methylation analysis and Smith degradation. A high percentage of end-groups indicates a large degree of branching, glucose and galactose being the main branch-points, linked at C-3 and C6. The hexoses are also present as unbranched residues in the chain, largely as (1 leads to 3)- and (1 leads to 4)-linked units and as end-groups. Arabinofuranosyl units constitute the main part of the non-reducing end-groups, and are also present as part of the chain. The polysaccharide chains are probably linked to protein through the hydroxyl group of hydroxyproline.
