Biological Activities
Lupinus albus has long been recognized for its diverse medicinal and practical applications across various traditional healing practices. Scientific investigations into Algerian empirical medicine have confirmed its potent antidiabetic properties, specifically through its ability to inhibit $\alpha$-glucosidase activity. Beyond its metabolic benefits, this plant also holds a significant place in the traditional agricultural toolkit of Central Italy. Local farmers and shepherds have frequently utilized the species for its effective antiparasitic qualities to protect livestock. Furthermore, its documented use as a natural repellent highlights the versatile biological activities inherent in this remarkable plant.
Compounds
Lupinus albus is a complex plant species characterized by several significant biochemical components and physiological adaptations. Research into its alkaloid profile has investigated the presence of anagyrine, though studies suggest certain peaks may actually correspond to 17-oxolupanine. The plant also demonstrates specialized metabolic responses to nutrient scarcity, such as the enhanced expression of phosphoenolpyruvate carboxylase in its proteoid roots during phosphorus deficiency. Furthermore, the nutritional value of its seeds is closely tied to essential elements, as the plant contains both sulphur and the amino acid methionine. Interestingly, the levels of these vital nutrients can be influenced by fertilization methods and various food processing techniques.
Conditions
Lupinus albus treats diabetes through its antihyperglycemic effects and its ability to inhibit $\alpha$-glucosidase activity. The plant also treats protein digestibility, with certain processing methods and dehulled seeds showing high digestibility levels comparable to casein. In livestock studies, Lupinus albus treats body weights by improving growth rates in various species such as broiler chicks and turkeys. It treats feed efficiency by enhancing the feed-to-gain ratio in poultry and maintaining similar performance levels in lambs. Furthermore, Lupinus albus treats 3.5% FCM in lactating Holstein dairy cows, with certain dietary inclusions significantly increasing milk production.
Preparations
Lupinus albus is prepared as seeds to study the availability of methionine and sulfur, as well as for consumption in various forms. It is also prepared as extracts, specifically ethanol-based solutions, to evaluate their potent inhibitory activities against α-glucosidase. Additionally, Lupinus albus is prepared as additives to wheat flour, a practice that has raised concerns regarding cross-allergenicity in peanut-allergic patients. The plant is further prepared as an aqueous suspension for oral administration in studies investigating antihyperglycemic effects in diabetic models. Finally, Lupinus albus is prepared as defatted flour to facilitate the electrophoretic separation and analysis of its albumin and globulin protein fractions.
Parts used
Lupinus albus is a versatile plant species that offers significant nutritional and medicinal value across its various biological components. The seeds are particularly notable for their methionine and sulfur content, which play crucial roles in protein quality and potential functional food applications. Beyond the seed, research into the intercellular fluid of the plant has revealed complex protein profiles within the leaves. These studies also indicate that specific enzymes, such as class III chitinase-lysozymes, are present throughout the stem and root tissues. By examining these different parts, scientists can better understand the full metabolic and defensive capabilities of the white lupine.
