The lipid content of Atriplex semibacata growing in Egypt was studied. The unsaponifiable fraction was identified by GLC. A series of hydrocarbons ranging from C(14)- C(28) in addition to cholesterol, stigmasterol and the triterpenoids α and β - amyrin were identified. GLC analysis of fatty alcohols fraction revealed the presence of six fatty alcohols in which dotriacontanol (C(32)H(66)O) was t...

Previous studies analyzing 2,200 plant extracts indicated anti-enterococcal activity in 25 extracts obtained from Brazilian forests' plants. In the present study, these extracts were subjected to microdilution broth assay (MDBA) and disk diffusion assay (DDA) using planktonic Enterococcus faecalis ATCC(®) 29212™ and were submitted to phytochemical analysis in TLC and HPLC. Three extracts obtain...
