D 3.2.1, several families of Angiospermae) and toxic compounds, such as andromedotoxins (D 6.3, Ericaceae), quinolizidine alkaloids (D 18, Sophora microphylla) and arbutin (D 22.2.5, Arbutus unedo) may be present — pollen may contain pigments, such as carotenes (D 6.5) and flavonoids (D 22.3.3), cinnamic acid derivatives (D 22.2) and cell wall constituents such as carbohydrates (D 1.4.1) and sporopollenins (D 6.5). 

N/0.01% Inc. C-2 26%, C-10 25%, C-15 16%. In this experiment and the one carried out in Sophora microphylla, only 2/3 of the activity was recovered In C-2,10, and 15. The higher level of activity found at C-2 and C-10 is rationalized on the basis of the following scheme, in which rings A and B of matrlne are derived from a dimer of A -piperidelne (1). This then later condenses with the monomer to yield the carbon skeleton of matrlne. Different pool sizes of the monomer and dimer could then result in different levels of activity in ring D and rings A/B.
