Alternatively, solvent partition or countercurrent techniques may be applied. In order to obtain an isoflavonoid-rich fraction from Erythrina species (Leguminosae) for further purification work, an organic solvent extract was dissolved in 90% methanol and first partitioned with hexane. The residual methanol part was adjusted with water to 30% and partitioned with t-butyl methyl ether-hexane (9 1). This latter mixture was then chromatographed to obtain pure compounds. ... 

Figure 15.23. The most important biologically mediated nitrogen conversion processes (compare Table 15.9). Natural N fixation occurs through certain blue-green algae and through certain bacteria, which live in symbiosis with plants (leguminosae). Microorganisms mediate, under aerobic conditions, the nitrification of NH4 (and NH3) to NOa and NO ". At low pe (pe < 6 at pH = 7) the reduction to is possible. Organic compounds can cause the reduction of NO to N2 (denitrification) (see reaction 3 in Table 15.9). NO and NjO may occur as intermediates, both in nitrification and denitrification (reactions 9 and 10 in Table 15.9).

Malonic acid (3) is particularly abundant in the Leguminosae although its function is still not entirely clear. Li and Copeland [17] described a study of the temporal and spatial distribution of organic acids in chickpea plants and investigated the different kinds of abiotic stress on organic acid... 

A survey has been contributed of the alkaloid content of 16 species of Spanish and Portuguese Leguminosae belonging to the Cytisus, Genista, Echinospartium, Stauracanthus, and Adenocarpus genera 13 quinolizidine or dipiperidine bases were identified, and their distribution in the various organs of the plants determined. 

These proteins occur in the seeds of many plants but are especially common in the Fabaceae (Leguminosae) (more than 600 species) and the Euphorbiaceae (lectins also occur in other organisms such as fungi, bacteria, and animals). In legumes, lectins are usually found in the cotyledons (Liener, 1991). Well-known plant lectins are concanavalin A, from jack beans Canavalia ensiformis), favin, from the broad bean (Vida faba), and phasin, from the kidney bean (Phaseolus vulgaris) (Ramshaw, 1982), The toxicity of lectins differs considerably (Liener, 1991 Liener et al, 1986). Data for lectins are given in Liener et al. (1986) and Lis and Sharon (1981).

The Type 1 proanthocyanidins are distributed almost ubiquitously in the woody plants, whereas Type 2 proanthocyanidins are confined to certain families in the Leguminosae and Anacardiaceae (see Sect. 7.7.3.1), often co-existing with Type 1 proanthocyanidins either in the same or different organs of the plant. However, the Type 2 tannins are of pre-eminent importance commercially as currently the two most important sources of condensed tannins for industrial applications are wattle Acacia mearnsii) bark and quebracho Schinopsis spp.) wood, which are both of this type (Chap. 10.3). Our current knowledge of these tannins is almost entirely due to the efforts of David Roux and his colleagues over the past three decades.
