Study of antioxidant activity and essential Oils composition from the Flowers and Fruits of Cryptocarya stocksii Meisn

The aim of this study was to investigate the flowers and fruits essential oil composition and antioxidant activity
of Cryptocarya stocksii, an endemic and vulnerable tree grows in the Western Ghats of India. The essential oils
were obtained by hydrodistillation using a Clevenger apparatus and analyzed by GC/MS. GC-MS analysis of
essential oil of flower and fruit revealed the presence of individual 24 different compounds corresponding to 99.87%
and 99.99% of the total oil respectively. The flower and fruit oil were dominated by α-Pinene (39.42% and 8.84%),
β-Pinene (17.96% and 4.87%), 3-Carene (29.52% and 1.92%) and Longifolene (6.53% and 19.12%) respectively.
Antioxidant activities were determined by four different test systems, namely, DPPH, FRAP, H2O2, and anti-lipid
peroxidation assay and result found to be dose dependent manner. This work represents the first study of the
chemical composition and anti oxidant of essential oils from flowers and fruits of C. stocksii.
