Gentianaceae

The following example comes from the work of Gottlieb and Kubitzki (1983) on the use of xanthones as indicators of relationships within Gentianaceae, a family [Pg.217]

Other examples in the Gottheb and Kubitzki (1983) paper, following similar statistical methodology and logic, concern chemical changes in the evolution of Aniba (Lauraceae) in the Amazon, and associated river basins and relationships among genera of Papilionoideae as a function of their accumulated alkaloids. These are complex examples that would repay careful study by interested readers. [Pg.219]

The toxic properties of Pteridium aquilinum L., the common bracken fern, have been known to humankind for a very long time. Two principal causes of trouble are its carcinogenic properties (M. Saito et al., 1975 I. A. Evans, 1976 Hirono, 1986) [Pg.219]

simpler compounds appear to vary among varieties of bracken as well. Both trans-o-cowmdixic acid [393] and the related coumarin [394] have been reported from var. caudatum (Bohm and Try on, 1967 Alonso-Amelot et ak, 1995), but not from other varieties that have been tested var. aquilinum from Europe and England, var. latiusculum from Europe, North America, and Japan, var. pubescens from western North America and Mexico, and var. esculentum from Australia and New Zealand (Alonso-Amelot et ak, 1995). [Pg.220]

Altogether 22 anthocyanins, including three produced by genetic engineering, have been reported to occur in flowers from the family Gentianaceae (Figure 10.14). Nineteen among these have been identified as novel compounds in the period of this review. The examined... [Pg.518]

Gentiopicroside is also contained in the herbal medicine Gentiana (Ryutan), which is the extract of the root of Gentiana lutea and has gastroprotective effects.117 It has a secoiridoid structure, which is a common constituent in members of the family Gentianaceae. [Pg.650]
