Phytochemical investigation of the lipids extracted from seeds of by GC-MS showed 43 cannabinoids, 16 of which are new. The extract is dominated by Δ-tetrahydrocannabinolic acid (A) and its neutral derivative -Δ-tetrahydrocannabinol-C (THC) and -Δ-tetrahydrocannabinol-C isomers with an ethyl-pentyl branched chain together with minor amounts of -Δ-tetrahydrocannabinol with a methyl-pentyl C branched side chain were identified as new natural compounds. Four cannabichromene isomers with a C side chain are postulated to be derived from the double bond migration at the terminal isoprenyl unit. C cannabichromene together with the neutral and acidic forms of cannabinol-C were also detected. The mass spectrum of these homologues as trimethylsilyl (TMS) derivatives are presented, and the fragmentation patterns are discussed.

A semisynthetic alkylated ESTRADIOL with a 17-alpha-ethinyl substitution. It has high estrogenic potency when administered orally, and is often used as the estrogenic component in ORAL CONTRACEPTIVES.
The transfer of STEM CELLS from one individual to another within the same species (TRANSPLANTATION, HOMOLOGOUS) or between species (XENOTRANSPLANTATION), or transfer within the same individual (TRANSPLANTATION, AUTOLOGOUS). The source and location of the stem cells determines their potency or pluripotency to differentiate into various cell types.
A child or adolescent who, when compared to others of the same age or experience, exhibits capability of high performance in intellectual, creative, or artistic areas, possesses an unusual capacity for leadership or excels in specific academic fields. (From PL 100-297, Sec. 4103, Definitions)
A 20 cM region of mouse chromosome 17 that is represented by a least two HAPLOTYPES. One of the haplotypes is referred to as the t-haplotype and contains an unusual array of mutations that affect embryonic development and male fertility. The t-haplotype is maintained in the gene pool by the presence of unusual features that prevent its recombination.
A MEPERIDINE congener used as an antidiarrheal, usually in combination with ATROPINE. At high doses, it acts like morphine. Its unesterified metabolite difenoxin has similar properties and is used similarly. It has little or no analgesic activity.
