A preparative gas chromatography (pGC) method was developed for the separation of volatile components from the methanol extract ofCurcumarhizome. The compounds were separated on a stainless steel column packed with 10% OV-101 (3 m × 6 mm, i.d.), and then, the effluent was split into two gas flows. One percent of the effluent passed to the flame ionization detector (FID) for detection and the remaining 99% were directed to the fraction collector. Five volatile compounds were collected from the methanol extract ofCurcumarhizome (5 g/mL) after 83 single injections (20 uL) with the yield of 5.1–46.2 mg. Furthermore, the structures of the obtained compounds were identified asβ-elemene, curzerene, curzerenone, curcumenol, and curcumenone by MS and NMR spectra, respectively.

Silica Gel Chromatography

A preparative gas chromatography (pGC) method was developed for the separation of isomers (cis- andtrans-asarone) from essential oil ofAcorus tatarinowii. The oil was primarily fractionated by silica gel chromatography using different ratios of petroleum ether and ethyl acetate as gradient elution solvents. And then the fraction that contains mixture of the isomers was further separated by pGC. The compounds were separated on a stainless steel column packed with 10% OV-101 (3 m × 6 mm, i.d.), and then the effluent was split into two gas flows. One percent of the effluent passed to the flame ionization detector (FID) for detection and the remaining 99% was directed to the fraction collector. Two isomers were collected after 90 single injections (5 uL) with the yield of 178 mg and 82 mg, respectively. Furthermore, the structures of the obtained compounds were identified ascis- andtrans-asarone by1H- and13C-NMR spectra, respectively.
