You can also prepare your own plant extract, as in the reference below. Use a plant species that herbivores avoid snch as spurges Euphorbia spp.) or false hellebore Veratrum viride). Separate plant parts such as leaves, stems, and roots. Grind plant parts separately with ethyl acetate in a blender. (In onr work, we extracted 60 g of roots of Euphorbia lathyris with 2(X)-ml ethyl acetate. For about 300 g plant tops we used 400-nil ethyl acetate.) Filter the extract, discard the plant tissue. 

Veratrum califomicum, commonly loiown as false hellebore or com lily, is a coarse, weedy plant that thrives between 6500-7000 feet of elevation and is avoided by most livestock, but not sheep [28]. The numerous erect stems of the plant are connected to each other by underground stems or rhizomes. Some of the stems bear open clusters (panicles) of dull greenish-white flowers. Fig. (3), whereas others end in a somewhat smaller leaf. The latter. Fig. (4), are a fascinating botanical curiosity. Each leaf blade is supported by a sheath that encircles the... 

Saffron genus Colchicum (Colchicum L.) produces colchicines. Metacolchicine is in Sandersonia aurantiaca and other colchicines in meadow saffron (Colchicum autumnale L.). Stereoidal alkaloids in the Liliaceae family are found in the Hellebore genus (Veratrum Bemch.). Jervine, cyclo-pamine (Figure 1.18), cycloposine, protoveratrine A, and protoveratrine B yield Veratrum album. Veramadines A and B are reported to be found in Veratratum mackii var. japonicum. O-Acetyljervine has been reported in the false hellebore (Veratrum lobelianum Bemch.). Steroidal alkaloids... 

Stilbenes originate from the same biosynthetic precursors as flavonoids, but have a different structure, since the polyketide portion undergoes a different type of cyclization including loss of one carbon by decarboxylation. Stilbenes occur in several umelated plants such as peanut (Arachis hypogaea), grapevine (Vitis vinifera), rhubarb (Rheum), false hellebores (Veratrum) and pine (Pinus) species. These compounds have antifungal properties. They are induced upon stress, injury, and fungal infection and can therefore be classified as phytoalexins.
