Antimicrobial components of some cruciferae plants (Diplotaxis harra Forsk. and Erucaria microcarpa Boiss.)

Bioactive lipids and antioxidant properties of wild Egyptian Pulicaria incise, Diplotaxis harra, and Avicennia marina

“…Oleic followed by stearic acids were the major fatty acids identified in D. harra, which together accounted for more than 50% of total FAMEs. High level of palmitic acid was also detected in lipidic extract and these results are in line with Hashem and Saleh (1999). In A. marina, palmitic followed by oleic were the major fatty acids, which comprising together ca.…”

“…The volatile constituents of D. harra showed high activity against yeasts than Gram-positive, Gram-negative bacteria and fungi. The nonmethylated fatty acids of the herb showed also strong activity against Grampositive and Gram-negative bacteria than yeasts and fungi (Hashem and Saleh 1999).…”

Phytochemical and pharmacological screening of Sterculiaceae species and isolation of antibacterial compounds

“…Palmitic (hexadecanoic) acid (CH 3 (CH 2 ) 14 COOH) is one of the most common saturated fatty acids in leaf lipids and also occurs in some seed oils (Gurr and James, 1971;Harborne and Baxter, 1993). It has previously been reported to be the major antibacterial compound in a mixture of fatty acids from Diplotaxis harra and Erucaria microcarpa (Hashem and Saleh, 1999), the fruit of Kigelia africana (Grace et al, 2002) and Pentanisia prunelloides (Yff et al, 2002).…”

Variation of glucosinolates in vegetable crops of Brassica rapa L. ssp. pekinensis

“…They are an important group of phytochemicals present exclusively in 16 botanical families of the order of Capparales, and they are particularly abundant in Brassicaceae (Fahey, Zalcmann, & Talalay, 2001). They and/or their breakdown products are well known for their fungicidal (Pedras, Chumala, & Suchy, 2003;Pedras, Sarwar, Suchy, & Adio, 2006), bacteriocidal (Hashem & Saleh, 1999;Lin, Kim, Du, & Wei, 2000), nematocidal (Zasada & Ferris, 2004) and allelopathic properties and have recently attracted intense research interest because of their cancer chemoprotective attributes (Fahey et al, 2001).…”
