Comparative study of Oxalis L. species growing wild in Egypt: GC-MS analysis and chemosystematic significance

Five Oxalis L. plants belonging to three different sections were collected and subjected GC-MS analysis evaluate understand the relationship between them from chemosystematic point of view. The revealed identification characterization thirty seven compounds non-polar chemical classes which nine (two aliphatic hydrocarbons, one diterpene, fatty acid, four acid esters alcohol) identified before genus while, rest for first time. results chemosystematically significant among species found be a good parameter in finding tangible demarcation O. corniculata var. repens, on other hand it is difficult differentiate by obtained data.
