Umbelliferae family

Ammi visnaga is a plant of the Umbelliferae family, which has been known and used for its therapeutic properties by the peoples of the Mediterranean basin since time immemorial. 

The cicutoxin-like compounds are known for their extreme and violent toxicity. There are other plant species that contain these polyacetylene type compounds, however none are as toxic as cicutoxin and oenanthotoxin. These species all come from the Umbelliferae family and include Falcaria vulgaris, Slum sisarum, Carum carvi, Aegopodium podagraria and Daucus carota. Daucus carota is the common carrot and it contains a similar cicutoxin-like compound, caratotoxin, but is less toxic (LD50 = 100 mg/kg i.v. in mice) than cicutoxin. Caratotoxin is found in minute amounts in carrots and is not considered a health concern for humans (Crosby and Aharonson, 1967).

A Cremocarp is the characteristic splitting fruit of the Umbelliferas family. It consists of two inferior akenes or mericarps separated from each other by a forked stalk called a carpophore. These mericarps usually cling to the forks of the carpophore for a time after the cremocarp splits, but sooner, or later fall. Fig. 100 (i).

Cavities are tubular spaces developed in plants due to cell deterioration. Cavities occur in anis, caraway, corriander, and fennel (members of the Umbelliferae family) and the needle oils of the Abies and Pinus.

The close relationships of larval growth rates and efficiencies (see Fig. 7.1 Waldbauer, 1968) with leaf nitrogen content is illustrated in Fig. 7.2. The symbols represent the mean performance ( SE) of the black swallowtail butterfly, Papiliopolyxenes, larvae for 11 different species of the Umbelliferae family at particular times of the growing season.

Swedes and turnips are both brassicas in which the principal phytochemicals of interest are glucosinolates found throughout the plant but particularly in the root. Parsnip is a member of the Umbelliferae family and like many members of this family, including celery (Apium graveolens), contains psoralen (Figure 7.6) which in sensitive people can cause blistering on exposure to light (see Section 7.3.5 and Chapter 5).
