Arachidonic acid gets its name from arachidic acid, the saturated C20 fatty acid isolated from peanut (Arachis hypogaea) oil.

Fatty acids have also great potential as synthons for tte preparation of secondary metabolites. Renewable sources include rapeseed Brassica rapa), sunflower (Helianthus annuus), soy bean Glycine max), peanut Arachis hypogaed), and linseed Linum usitatissimum). These plants can be genetically engineered to furnish fetty acids in high-purity (Bierman 2000). 

Catechin and the proanthocyanidin prodelphinidin B3 are, respectively, the major monomeric and dimeric flavan-3-ols found in barley and malt where prodelphinidin B3 is the main contributor for the radical scavenging activity [Dvorakova et al., 2007], Proanthocyanidins have also been detected in nuts. Hazelnuts (Corylus avellana) and pecans (Carya illinoensis) are particularly rich in proanthocyanidins containing ca. 5 g kg, whereas almonds (Prunus dulcis) and pistachios (Pistachio vera) contain 1.8-2.4 mg kg 1, walnuts (Juglans spp.) ca. 0.67 g kg, roasted peanuts (Arachis hypgaea) 0.16 g kg, and cashews (Anarcardium occidentale) 0.09 g kg 1 [Crozier et al., 2006c]. Dark chocolate derived from the roasted seeds of cocoa (Theobroma cacao) is also a rich source of procyanidins [Gu et al., 2004], Monomeric flavan-3-ols and the proanthocyanidin B2, B5 dimers, and Q trimer are found in fresh cocoa beans (Fig. 1.13). Flavan-3-ols have also been detected in mint...

Peanuts (Arachis hypogea) contain about 25% protein and are reported to have two proteins, namely, arachin and conarachin, of which the former is the major one. Isolation, composition, and properties of peanut proteins were reviewed by J. C. Arthur, Jr. in 1953, a review covering the literature up to 1951 (Peanut protein isolation, composition and properties...

Peanut (Arachis hypogea) belongs to the Papilionacea family of the Fabales order, which also includes pea, bean, soybean, lupine, chickpea, and lentil (Duranti and Gius 1997, Makri et al. 2005).

Since L-arabinose is a constituent unit of many natural products a number of methylated derivatives of this sugar have been isolated by the hydrolysis of methylated polysaccharides. Thus methylated peanut (Arachis hypogea) araban and sugar beet araban give trimethyl-L-arabofuranose, 2,3-dimethyl-L-arabinose and 2-methyl-L-arabinose in equal proportions.84 From methylated gum arabic trimethyl-L-arabo-furanose and 2,5-dimethyl-L-arabinose have been isolated.85 These same compounds have also been isolated from methylated cherry gum86 and methylated damson gum,87 whereas methylated mesquite gum88 affords 3,5-dimethyl- and 2,3,5-trimethyl-L-arabinose on hydrolysis.
