Volatile compounds of the Hallabong (Citrus kiyomi × Citrus ponkan) blossom
The objective of this study was to identify and compare the volatile compounds of liquid essential oils and volatiles of headspace-solid phase microextraction (HSSPME) of the hallabong blossom. SPME is a sampling technique based on sorption of analytes into a polymeric material that coats a silica fiber. Two different fiber coatings tested to evaluate the extraction efficiencies of volatiles. The hallabong blossom exhibited 5 major volatile compounds: linalool (28.89–43.24%), limonene (0.39–23.06%), β-myrcene (0.38–16.67%), sabinene (1.37–11.42%), and 4-terpineol (1.26–6.12%). The amounts of identified compounds in the hallabong blossom were more abundant in carboxen/polydimethylsiloxane (CAR/PDMS) fiber than in PDMS fiber.
