Lupinus luteus

Smirnova and Moshkov have investigated the effects of the removal of leaves or buds and of grafting on the alkaloidal content of lupins, and Wallebroek has studied the alkaloidal and nitrogenous metabolism of Lupinus luteus seeds on germination. ... 

Rothwell and Wain (126) have isolated in crystalline form a growth inhibitor from Lupinus luteus (yellow lupine) pods which they have partially characterized. Analytical data suggested that the inhibitor possessed the characteristics of an unsaturated hydroxyketo acid. Inhibition in the wheat coleoptile cylinder test was obtained with concentrations of 0.25 to 1.0 p.p.m.

Lupinus luteus L., Lupinus hispanicus L., Lupinus hirsutus L. They have also been found in Anabasis aphyla. In absolute configuration, lupinine is in its (—)-form, which is non-stable thermally, and is easily epimerized to epilupinine, which is a stable (+)- form of lupinine . The melting point of (—)-lupinine is 70-71 °C, of mixed (+ and —)-lupinine 63-64°C, and of (+)-lupinine (synthetic)...

Alkaloids 36-41 were isolated from Lupinus luteus L. seedlings. They are considered to be lupinine esters with 4-hydroxycinnamic acids (94-100). The structures of these new alkaloids were elucidated on the basis of H NMR, MS, and chemical and enzymatic transformations. All these alkaloids were obtained from lupinine and hydroxycinnamic acid by two enzymatic systems (96-97) ligase catalyzed formation of the CoA-thioester, and transferase catalyzed lupinine ester formation from the CoA-thioester.

Within the complex flavonols, C-5 substitution is by far the most prominent trend in terms of numbers of compounds and sources. Also, the number of structurally different C-5-residues is remarkable. Apart from the common 3,3-dimethylallyl and the rarer 1,1-dimethylallyl, several hydroxylated C-5-residues such as in topazolin hydrate, isolated from roots of Lupinus luteus (Fabaceae compound 94 in Table 12.4). Another source of such compounds is the whole plant of Duranta repens (Verbenaceae). Plant organs accumulating C-prenylflavo-nols range from buds to leaves and from aerial parts to roots. Only the bud constituents may be considered as exudate compounds. From Lilium candidum, a more complex flavonol was reported (Figure 12.8). This genus also accumulates N-containing flavonoid derivatives discussed earlier. ...

There have been reports of L-arabinosidase activity in various plants. The presence of a-L-arabinofuranosidase was confirmed in callus cultivation of S. japonica, and in an extract of germinating seeds of Lupinus luteus.
