“…In spite of our efforts, we were not able to obtain a pure compound. However, the structure was elucidated using the concept of ‘Extraction NMR’ . Indeed, NMR experiments have been conducted on a fraction of chromatography (F”4) which contained the unidentified compound (40%), β‐elemol (18%), β‐eudesmol (18%), trans ‐guai‐6‐en‐10β‐ol (12%) and α‐eudesmol (8%).…”

The composition of an oil sample isolated from leaves of Fortunella japonica (Thunb.) Swingle was investigated by combination of chromatographic and spectroscopic techniques. Among the compounds present at appreciable amounts, a special attention was brought to sesquiterpenes bearing a tertiary alcohol function and particularly to germacra-1(10),5-dien-4α-ol. Indeed, identification of diastereoisomers α and β of germacra-1(10),5-dien-4-ol has been the subject of controversy in the literature. We report here for the first time 13

“…The chromatographic profile as well as the 13 C-NMR spectrum of fractions F2, F8 and F9 demonstrated that every fraction contained an unidentified major component. Therefore, it was decided to combine column chromatography (CC on silica gel using a gradient of solvents pentane/diethyl ether) and the concept of “extraction” NMR [18,19] to identify the major components of every fraction.…”

Abstract:In order to get better knowledge about the volatiles produced by Xanthocyparis vietnamensis, a species recently discovered in Vietnam, its wood oil has been analyzed by a combination of chromatographic (GC, CC) and spectroscopic (GC-MS, 13 C-NMR) techniques. Forty components that accounted for 87.9% of the oil composition have been identified. The composition is dominated by nootkatene (20.7%), 11,12,13-tri-nor-eremophil-1(10)-en-7-one (17.2%), γ-eudesmol (5.1%), nootkatone (4.7%), valencene (3.5%) and 13-nor-eremophil-1(10)-en-11-one (2.6%). The structure of two new compounds-10-epi-nor-γ-eudesmen-11-one and 12-hydroxy-isodihydroagarofuran-has been elucidated, while 11,12,13-tri-nor-eremophil-1(10)-en-7-ol is reported as a natural product for the first time. The composition of X. vietnamensis wood oil varied drastically from those of leaf oils, dominated by hedycaryol (34.4%), phyllocladene (37.8%) or by pimara-6(14)-15-diene (19.4%).
