VOLATILE COMPONENT COMPOSITION OF BALLOTA NIGRA SUBSP. ANATOLICA AT DIFFERENT VEGETATION PERIODS IN ÇAMLICA PROVINCE OF KÜTAHYA CITY, TURKEY.

The volatile component composition of leaves and flowers for Ballota nigra subsp. anatolica P.H. Davis that were collected between 2015 and 2016 from Çamlıca provice of Kütahya city during three different vegetation periods as pre-bloom, bloom and post flowering were determined by gas chromatography mass spectroscopy (GC-MS) after solid phase micro extraction (SPME). 59 different volatile oil components were determined of Ballota nigra subsp. anatolica. As main components, Hexenal (17.60%), germacrene D (6.70%) and β-caryophyllene (8.80%) were found during pre-blooming period, also Hexenal (21.16%), germacrene D (7.77%) and β-caryophyllene (10.03%) in blooming period and Hexenal (15.88%), germacrene D (7.60%) and β-caryophyllene (9.48%) in post-flowering period.
