In vivo and in vitro Volatile Constituents of the Flowers of Xylopia aromatica by HS‑SPME/GC-MS

Xylopia aromatica (Lam.) Mart. (Annonaceae) is a typical species from the Brazilian cerrado that presents medicinal properties. The plant distinguished by its large white flowers which produce pleasant fragrance. X. characterized wide range of application. These characteristics have motivated us to investigate volatile organic compounds (VOCs) via in vivo and vitro protocols headspace solid-phase microextraction (HS‑SPME) technique combined with gas chromatography-mass spectrometry (HS-SPME/GC‑MS). Four different fibers, extraction times temperatures were parameters changed lead maximum profiling constituents. Data analyzed using principal component analysis (PCA). A total 77 VOCs extracted floral scent, 52 68 sampling, respectively, 48 reported for first time literature as constituents flowers. identification successfully performed through HS-SPME/GC-MS. PCA data allowed led number VOCs, polyacrylate (PA) carboxen/polydimethylsiloxane (CAR/PDMS) 60 min temperature 29.0 °C. Among identified, sesquiterpenes predominated, comprising about 61.04%.
