Ingia / Ingia

Mitochondrial monoamine oxidase (MAO) of human brain and liver was inhibited by low concentrations of cannabis extract (CE) and a cannabinoid fraction isolated from it. delta 1-Tetrahydrocannabinol (THC) did not elicit any inhibitory effect on the enzyme. The inhibition of MAO activity by CE and by

Rapid isolation procedure for Δ9-tetrahydrocannabinolic acid A (THCA) from Cannabis sativa using two flash chromatography systems.

Ingia / Ingia

Two isolation procedures for Δ9-tetrahydrocannabinolic acid A (THCA), the biogenetic precursor in the biosynthesis of the psychoactive Δ9-tetrahydrocannabinol (THC) in the cannabis plant, are presented. Two flash chromatography systems that can be used independently from each other were developed to

Confirmation of cannabis use. II. Determination of tetrahydrocannabinol metabolites in urine and plasma by HPLC with ECD.

Ingia / Ingia

Simultaneous determination of delta 9-tetrahydrocannabinol (THC) and its major metabolites--11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (THC-COOH) and 11-hydroxy-delta 9-tetrahydrocannabinol (11-OH THC)--in urine and plasma by HPLC with electrochemical detection (LC/EC) was studied. After

In-tube solid-phase microextraction with a dummy molecularly imprinted monolithic capillary coupled to ultra-performance liquid chromatography-tandem mass spectrometry to determine cannabinoids in plasma samples.

Ingia / Ingia

A selective and sensitive method that uses automated in-tube solid-phase microextraction coupled to ultra-performance liquid chromatography-tandem mass spectrometry (in-tube SPME/UHPLC-MS/MS) was developed to determine cannabidiol (CBD) and Δ9-tetrahydrocannabinol (Δ9-THC) in plasma samples. A new

Synthetic cannabinoids in "spice-like" herbal blends: first appearance of JWH-307 and recurrence of JWH-018 on the German market.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Herbal smoking blends, available on the German market were analyzed and several known synthetic cannabinoids were identified (JWH-122 and JWH-018). In addition, we isolated a new active ingredient by silica gel column chromatography and elucidated the structure by nuclear magnetic resonance (NMR)

Analysis of choline and atropine in hairy root cultures of Cannabis sativa L. by capillary electrophoresis-electrospray mass spectrometry.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

We describe a capillary zone electrophoresis method coupled to electrospray ionization (ion trap) mass spectrometry (CZE-ESI-MS) for the identification and determination of choline and atropine compounds in hairy root extracts from Cannabis sativa L. Fused-silica capillary and an alkaline solution

Analysis of anandamide, an endogenous cannabinoid substance, and of other natural N-acylethanolamines.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Recent reports have suggested that N-arachidonoylethanolamine (anandamide) acts as an endogenous ligand for cannabinoid receptors in mammalian brain. Here we describe methods for the extraction, purification and analysis of anandamide and related N-fatty acyl-ethanolamines (NAEs). Liquid-phase

Ingia / Ingia

delta 9-Tetrahydrocannabinol (delta 9-THC), cannabinol, cannabidiol and cannabichromene were detected in commercially available cannabis seeds by silica gel TLC and gas chromatography. These cannabinoids existed in rather high content (0.10-2.02 mg/100 g of seeds) in the feed for birds especially

Determination of cannabinoids by gas chromatography-mass spectrometry and large-volume programmed-temperature vaporiser injection using 25 microl of biological fluid.

Ingia / Ingia

This paper presents a GC-MS confirmation method, based on large-volume programmed-temperature vaporisation (PTV) injection, for the determination of cannabinoids in plasma samples (or whole blood) with deuterium-labelled internal standards using only 25 microl of biological fluid. The analytes,

Ingia / Ingia

Cannabis is widely smoked in Europe and its increasing use is becoming a major public health problem. Adulterating cannabis with glass beads or sand is a new trick used by dealers to increase the weight and boost profits. These recent practices are not without danger. We report two cases of

Solid-phase extraction-liquid chromatography-tandem mass spectrometry method for the qualitative analysis of 61 synthetic cannabinoid metabolites in urine.

Ingia / Ingia

This article comprises the development and validation of a protocol for the qualitative analysis of 61 phase I synthetic cannabinoid metabolites in urine originating from 29 synthetic cannabinoids, combining solid-phase extraction with a reversed phase silica-based sorbent (phenyl) with liquid

Development of rapid and simple method for DNA extraction from cannabis resin based on the evaluation of relative PCR amplification ability.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

In recent years, analysis of cannabis DNA has been increasingly used in forensic drug tests. However, in the case of cannabis resin, a processed marijuana product, complicated procedures are required for the extraction of clean DNA, as the presence of various impurities inhibits PCR amplification.

WIN-55,212-2 chronically implanted into the CA3 region of the dorsal hippocampus impairs learning: a novel method for studying chronic, brain-area-specific effects of cannabinoids.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

We report here that local hippocampal WIN-55,212-2 implants release this cannabinoid agonist for extended periods, the release is restricted to the implanted brain region and is behaviorally active. Radiolabeled WIN-55,212-2 was implanted bilaterally into the CA3 region of the dorsal hippocampus by
