constituents in this plant as if all specimens analyzed were 
referable C. sativa, realizing that this may or may not be the 
case. There is little dispute that the major active hallucinogen in 
Cannabis is A’-tetrahydrocannabinol. To date, at least 50 
cannabinoids, or rearranged cannabinoids, have been isolated 
from the genus. Most of these are trace constituents, and onlya 
few are judged to be artefacts. The structures of the major 
cannabinoids are presented in Figures 2-11. 
Cc. NON-CANNABINOID CONSTITUENTS OF CANNABIS. Although little 
is known of the contribution of non-cannabinoids to the biologi- 
cal activity of marihuana, the constituents recognized will be 
presented for the sake of completeness. 
Flavonoids. Cosmosioside, orientin and vitexin (Paris and 
Paris 1973); and 2”-0-glucopyranosylorientin and 2”’-0-gluco- 
pyranosylvitexin (Segelman et al. 1978). 
Triterpenes. Epi-friedelanol, friedelanol and friedelin (Slatkin 
et al. 1971). 
Sterols. Campesterol (Fenselau and Hermann 1982; Foote 
and Jones 1974; Slatkin et al. 1975a; and Turner and Mole 
1973), B-sitosterol (Fenselau and Hermann 1972; Foote and 
Jones 1974: Itokawa et al. 1975; Slatkin et al. 197S5a; Turner and 
Mole 1973); stigmasta-4,22-dien-3-one, stigmast-5-en-3-8-ol-7- 
one, stigmasta-5,22-dien-3-B-ol-7-one, campest-4-en-3-one and 
stigmast-4-en-3-one (Slatkin et al. 1975a); and ergosterol and 5 
a-stigmasta-7,24(28)-dien-3B-ol (Novotny et al. 1976); Sa-stig- 
mast-22-en-3-one, Sa-stigmasta-3-one, campesterol, and Sa- 
ergostan-3-one (Itokawa et al. 1975). 
Essential Oil Analyses. Several monoterpenes, sesquiterpenes, 
phenylpropanoids and phenolic compounds (Bercht et al. 1971 
and 1974; Hendriks et al. 1975; Hood et al 1973; Malingre et al. 
1975; Stahl and Kunde 1973; Stromberg 1974). 
Aliphatic Hydrocarbons. C22-C3; n-alkanes (Adams and Jones 
1973; Mobarak et al. 1974a, 1974b; and Rasmussen 1975); iso- 
alkanes Cys; C27 and C2» (Adams and Jones 1973) and anteiso- 
alkanes C25, Cog and C30 (Adams and Jones 1973). 
Fatty Acids. Several normal fatty acids have been reported 
(Itakawu et al. 1975; Romanenko 1974; Stepanova 1973). 
Amino Acids, Proteins, Nucleosides. The following amino
