摘要:

AbstractThe empyreumatic wood oils ofJuniperus oxycedrusL. andJuniperus phoeniceaL., after separation on a silica gel column, resulted in a hexane fraction which was analyzed by GC/MS.Thirty compounds were identified in each fraction: they make it possible to determine unambiguously the botanical origin of each oil considered.

摘要:

AbstractA new chemotype ofMentha longifolia(L.) Hudson was selected from populations growing wild in the Piedmont Valley (Italy). The oils obtained by steam distillation were analysed using gas chromatography while the components were identified using gas chromatography‐mass spectrometry. The plant was found to possess a high content of piperitenone oxide (77.43%) and moderate amounts of germacrene D (3.7%) and 1,8 cineole (1.61%). The chromosome number (2n = 24) was determined in metaphasic squashes of root tip

摘要:

AbstractThe essential oilScutellaria laterifloraL. (Labiatae) growing wild in northern Iran obtained by hydrodistillation was investigated using TLC, LSC, GLC, and GLC‐MS methods. The oil is mainly composed of sesquiterpenes (78.3%) of which τ‐cadinene (27%), calamenene (15.2%), β‐elemene (9.2%), α‐cubebene (4.2%), and α‐humulene (4.2%) are the major components. At least 73 compounds were present in the oil. Non‐terpenoid constituents were found in low

摘要:

AbstractThe essential oil ofDracocephalum kotschyiBoiss. (Labiatae) growing in the mountainous region of northeastern Iran have been analysed by TLC, LSC, GLC, and GLC‐MS. The main components of the oil were citral, caryophyllene, terpinyl acetate, and myrcene. Sesquiterpenoids, phenylpropanoids, and aliphatic compounds found in this oil have not been previously reported from other species ofDracocephalu

摘要:

AbstractThe chemical composition of essential oils from the flowering plants of four Santolina L. species was examined by gas chromatography, gas chromatography‐mass spectrometry, infrared spectroscopy and nuclear magnetic resonance (1H NMR and13C NMR). The essential oil of S. canescens Lag. was rich in camphor (15.0%). The other major constituents of this species and of S. rosmarinifolia L. were 1,8‐cineole, β‐pinene, myrcene, sabinene, ar‐curcumene and β‐eudesmol. The oil of S. pectinata Lag. and of S. semidentata Hoffmanns.&Link contained β‐eudesmol, nerolidol + spathulenol, α‐cadinol and a sesquiterpene alcohol MW 220. The oil of S. pectinata also contained τ‐cadinol, γ‐eudesmol and elemol as major components. The absence of yomogi alcohol and artemisia ketone in the oils from S. canescens and S. rosmarinifolia is

摘要:

AbstractMelaleuca leucadendraL. (family Myrtaceae) exists in three chemotypes, the volatile leaf oil of two of which are characterized by very high contents of the phenylpropanoids methyl eugenol of E‐methyl isoeugenol (up to 99% and 88% respectively). In addition to small amounts of trans‐β‐ocimene and linalol, numerous sesquiterpenes, often in traces only, are also present in these two chemotypes. Limited progeny studies indicated that the methyl eugenol form might breed true whilst seed from the methyl isoeugenol form yielded a mixture of both chemotypes in approximately equal propo

摘要:

AbstractThe leaf oil of four varieties of Algerian sweet orange were examined by GC and GC‐MS. In total, 68 constituents were identified from which 50, 54, 38 and 43 compounds were found to be present in the leaf oils of Washington‐navel, Valencia, Sanguine and Portuguese varieties respectively. Of the 68 constituents, 34 were characterized in sweet orange leaf oil for the first t
