Compound Names, Structures, and Sources

The names (Table 1 [pp. 7–59]) and structures (Figure 1 [pp. 219–384]) of diterpenes reported from the Compositae are organized according to skeletal type following the sequence indicated in Figure 2 (p. 392). If a name was assigned to a structure at the time the compound was reported, that name was included in Table 1. Otherwise, the structure was given a name compatible with the names previously assigned to related compounds. If more than one name was applied in the literature to the same structure, usually the first-published name was included in Table 1, followed by additional names listed within brackets. The compound number listed with each name was used throughout this treatment when reference to the compound was made. Comments about a reported compound were also included in brackets on a line below the compound name. Usually these comments describe situations in which the name applied to the compound was incompatible with either the illustrated structure or the published spectroscopic data.
