Potency Trends of Δ9‐THC and Other Cannabinoids in Confiscated Cannabis Preparations from 1993 to 2008 *
The data showed an upward trend in the mean Δ9‐tetrahydrocannabinol (Δ9‐THC) content of all confiscated cannabis preparations, which increased from 3.4% in 1993 to 8.8% in 2008, mainly due to the increase in the potency of nondomestic versus domestic samples. Expand
Characterization of Aloeride, a new high-molecular-weight polysaccharide from Aloe vera with potent immunostimulatory activity.
A new immunostimulatory polysaccharide called Aloeride from commercial aloe vera (Aloe barbadensis) juice is characterized and its potency for macrophage activation accounts fully for the activity of the crude juice. Expand
GC-MS analysis of the total delta9-THC content of both drug- and fiber-type cannabis seeds.
A GC-MS method was performed to determine the total delta9-THC content in both drug- and fiber-type cannabis seeds, finding that drug-type seeds were found to contain much higher levels than fiber (hemp) seeds, and the bulk of delta9/g is located in the testa, mainly on the outside. Expand
Potency trends of delta9-THC and other cannabinoids in confiscated marijuana from 1980-1997.
The analysis of 35,312 cannabis preparations confiscated in the USA over a period of 18 years for delta-9-tetrahydrocannabinol (delta9-THC) and other major cannabinoids is reported, showing that the potency of confiscated marijuana samples has continuously risen, going from 3.1% in 1992 to 4.2% in 1997.

Comparison of the subjective effects of Delta(9)-tetrahydrocannabinol and marijuana in humans.
The results support the idea that the psychoactive effects of marijuana in healthy volunteers are due primarily to THC. Expand
Comparison of the subjective effects of Δ9-tetrahydrocannabinol and marijuana in humans
Rationale. There has been controversy about whether the subjective, behavioral or therapeutic effects of whole plant marijuana differ from the effects of its primary active ingredient,Expand
Isolation of a galactomannan that enhances macrophage activation from the edible fungus Morchella esculenta.
The edible mushroom Morchella esculenta is among the most highly prized and morphologically recognizable fungi in the world. We describe the isolation from a polar extract of M. esculenta carpophoresExpand
Isolation of three high molecular weight polysaccharide preparations with potent immunostimulatory activity from Spirulina platensis, aphanizomenon flos-aquae and Chlorella pyrenoidosa.
Three new high molecular weight polysaccharide preparations isolated from food-grade microalgae that are potent activators of human monocytes/macrophages are identified: "Immulina" from Spirulina platensis, "Immunon" from Aphanizomenon flos-aquae, and "Immurella" from Chlorella pyrenoidosa. Expand
The volatile oil composition of fresh and air-dried buds of Cannabis sativa.
Drying of the plant material had no effect on the qualitative composition of the oil and did not affect the ability of individuals familiar with marijuana smell to recognize the odor. Expand
Cyclooxygenase‐2 inhibitory and antioxidant compounds from the truffle Elaphomyces granulatus
The ethanol extract of fruiting bodies of Elaphomyces granulatus, a truffle‐like fungus, was evaluated for cyclooxygenase‐2 (COX‐2) enzyme inhibitory and antioxidant activities and showed a potent antioxidant effect. Expand
