Phytochemical composition and bioactivities of lupin: a review

Abstract

Lupin is a nonstarchy grain legume with high protein, dietary fibre and low fat contents. The industrial shift of lupin seed utilisation from feed to food has recently increased the scientific interest to explore its phytochemical composition and biological activities. Lupin seeds contain significant amounts of polyphenols, carotenoids, phytosterols, tocopherols, alkaloids and peptides with antioxidant, antimicrobial, anticarcinogenic and anti-inflammatory activities. Among polyphenols, genistein and their derivatives (isoflavones) are of great importance because of their phytoestrogenic potential. This comprehensive review will help out the readers in understanding the phytochemicals present in lupin and their benefits.

White lupin (Lupinus albus L.) - nutritional and health values in human nutrition - a review

“…Phenolic compounds produced at the end of plant maturity and accumulated mainly in seed coats constitute natural protection against diseases and pests, and show antioxidative, antifungal, and an-Review doi: 10.17221/114/2016-CJFS tibacterial properties; however, Khan et al (2015) did not show any correlation between antioxidant activity and phenolic contents. Petterson & Fairbrother (1996) found small amounts of them in white lupin seeds (0.23-0.52%), while Lampart-Szczapa et al (2009) detected slightly above 2 mg/100 g in dehulled raw seeds.…”

“…Carbohydrates. Lupin seeds and seed coats contain various types of carbohydrates, mainly nonstarch carbohydrates (Khan et al 2015), which are the most abundant in seeds. In the seed coat, apart from a small amount of proteins and fats, structural polysaccharides prevail: cellulose, hemicellulose, and pectins, while in the cotyledons -non-structural polysaccharides of cell walls (Straková et al 2006;Vecerek et al 2008), with the major proportion of galactose, arabinose, and uronic acid (Mohamed & Rayas-Duarte 1995;Petterson 1998).…”

“…They have a protective function in plants and seeds and are synthesised in response to biotic and abiotic stresses (phytoalexins). They have been recognised as useful substances preventing the occurrence of breast cancer, osteoporosis, and hot flashes during menopause, they show hypocholesterolaemic properties (Khan et al 2015), whereas cholesterol content reduction is connected with the stimulation of LDL fraction receptors (Sirtori et al 2004), most likely due to the reabsorption of bile acids, which affects reduction in solubility and in LDL cholesterol fractions (Martins & Bento 2007). The highest content of isoflavones in seeds is characteristic of soybean.…”

“…Also germination is used as a process to increase the nutritional value of many legumes (Khan et al 2015). Seed germination causes a reduction in the content of alkaloids, phytynians, and oligosaccharides (Dagnia et al 1992).…”

Development of a fermented product with higher phenolic compounds and lower anti‐nutritional factors from germinated lupin ( Lupinus angustifolius L.)

“…However, some nutrients in lupin have poor bioaccessibility which creates hurdles to overcome malnutrition in some of the developing countries (Khan, Karnpanit, Nasar-Abbas, Huma, & Jayasena, 2015).
