Phytochemical Diversity in Seven Grapevine Varieties Using GC-MS

The aim of the current study was to extract the active compounds of seven grape varieties cultivated in Duhok Governorate, Kurdistan Region of Iraq, for the 2023 season. The varieties included (Hejazi, Tre rash, Eayn althawr, Superior seedless, Moon drop, Crimson, Samarkandi). The results indicated that the leaves of grape varieties contain many active compounds, and the number and concentrations of these active compounds vary among the studied varieties. The number of active compounds according to the sequence was Hejazi 61 with highest compound of Methyl linolenate (6.71%), Superior seedless 36, Moon drop 33, Tre rash and Crimson 22, Eayn althawr 14, and Samarkandi 13 with 22.50 of α-Tocospiro-B . The compound Methyl palmitate appeared at its highest levels in the varieties (Tre rash, Eayn althawr, Superior seedless, Moon drop, Crimson), with values of (16.02%, 26.53%, 21.39%, 18.29%, 32.16%), respectively. GC-MS analysis confirmed that there is a biochemical diversity in the given grapevine varieties. Therefore, these varieties could distinguish via the highest compound appeared in GC-MS analysis.
