Biological Activities
Compounds
Lupinus angustifolius serves as a complex biological source for various specialized chemical compounds. Research utilizing capillary gas chromatography has identified several major alkaloids within the species, including lupanine, 13-hydroxylupanine, and alpha-isolupanine. Furthermore, studies investigating the alkaloid profiles of different lupin selections have specifically looked for the presence of anagyrine. Beyond these alkaloids, the plant also contains significant storage cell wall polysaccharides such as galactan. Understanding these diverse chemical constituents is essential for characterizing the nutritional and structural properties of this Mediterranean legume.
Conditions
Lupinus angustifolius affects digestibility in various ways, such as lowering fecal nitrogen digestibility in rats and calves while increasing ileal starch digestibility. In broiler chickens, the consumption of this plant leads to acute signs of toxicity, including leg weakness and muscle paralysis. High doses of lupin alkaloids in rats are also associated with the presence of altered foci of liver parenchymal cells. Furthermore, certain triterpenoid saponins derived from the plant demonstrate antifungal activity against Candida albicans. Finally, diets containing lupine have been shown to cause decreased food intake and growth rate in both rats and broiler chickens.
Preparations
Lupinus angustifolius is examined in various forms to determine its chemical and nutritional composition. Researchers analyzed the plant when it is prepared as whole seeds, which contain significant protein and crude fiber levels. The studies also investigated the specific properties of the plant when it is prepared as dehulled seeds. Additionally, the chemical makeup of the plant was assessed when it is prepared as testa. These different preparations allow for a comprehensive evaluation of the nutritional value of the species.
Parts used
Lupinus angustifolius is a legume species that can be utilized in various dietary studies, specifically through the consumption of its seed. Research involving long-term feeding trials has examined how diets based on these seeds affect the body composition and organ weights of rats. While all legume-based diets initially reduced growth rates, the specific impact of the lupin seed was found to be relatively moderate compared to other varieties. Notably, long-term exposure to these seeds resulted in a significant increase in the relative weight of the caecum and colon. These findings help clarify the physiological responses to different legume components during extended periods of consumption.
