Oil from Iris rhizomes is widely used in perfumery, cosmetology, and medicine owing to its regenerative and bactericidal properties [1]. The chemical compositions of essential oils from rhizomes of I. medwedewii and I. carthaliniae (Iridaceae) have not been previously studied. I. carthaliniae Fomin and I. medwedewii Fomin are perennials with thick creeping rhizomes. They are indigenous to several Azerbaijan districts (Lankaran, Masally, Agdash, Terter) in littoral marshes, moist locations, and bottoms (I. carthaliniae) and also along dry rocky slopes in the middle belt of Diabara mountains (I. medwedewii) and in the Low Caucasus Mountains (Shakhbuz, Julfa, Gek-Gel, Dashkesan) [2].The goal of the present work was to study the constituent composition of essential oil from rhizomes of I. medwedewii and I. carthaliniae of the Azerbaijan flora. Rhizomes of both species were collected in May 2014 in Gosmalyan and Pirasora, Lerik District, and of I. carthaliniae in Masally District during flowering in natural habitats. Essential oil (EO) was obtained by steam distillation for 12 h in an apparatus consisting of a 25-mL round-bottomed flask, a reflux condenser, and a water bath. The method allows EO to be isolated from plant material with trace quantities of EO [3]. The constituent composition of the plant rhizomes was studied by GC-MS [4] on an Agilent Technologies 6890N GC with a 5973 mass-spectrometric detector. The analytical conditions were published earlier [5]. Constituents were identified using the NIST05 and Wiley 2007 mass-spectra libraries in combination with the AMDIS and NIST identification programs.The EO contents of the air-dried raw materials were 0.2% for I. carthaliniae and 0.6% for I. medwedewii. A pairwise comparison of the EO constituent compositions for the two species found 35 common constituents, 42 for I. carthaliniae and 40 for I. medwedewii. Table 1 presents the results.The contents of the constituents varied from 0.01 to 34%. The EO contained terpenoids, their O-containing derivatives (alcohols, ketones, aldehydes, esters), aromatic compounds, triterpenoids, and carboxylic acids.The EO contained acyclic and monocyclic monoterpenoids such as cis-and trans-linalool oxide, p-menth-1-en-8-ol, and terpen-4-ol. The total monoterpenoid contents were 0.4% for I. carthaliniae and 0.5% for I. medwedewii.The common sesquiterpenes for both species were E-farnesene, germacrene D, trans-caryophyllene, G-cadinene, spathulenol, caryophyllene oxide, and D-and E-cadinol. Calamenene (0.1%) was identified only in I. medwedewii; D-and E-bisabolene epoxides, in I. carthaliniae. The rare tricyclic sesquiterpenoid D-copaene, which is characteristic of Pinus sylvestris sap, was detected in EO of the plants. The sesquiterpenoid contents were 2.1% in rhizomes of I. carthaliniae and 1.1% in those of I. medwedewii.The norterpenoids E-ionone, trans-2,6-J-irone, and D-irone that give Iris oil a violet aroma were detected for the first time [6]. The norterpenoid contents in rhizomes were 0.1% for I. carthaliniae and 0.02% for...
By extraction with acetone, the roots of Persian giant fennel Ferula persica Willd., ram. Apiaceae, gathered during the fruit-ripening period in Gobustan (Azerbaidzhan), have yielded a resin from which four substances have been isolated by the chromatography and rechromatography of the individual fractions, using various absorbents (alumina, silica gel). Sustance (1), composition C17H220~, mp 164-166°C (from aqueous ethanol) had in its IR spectrum £he absorption bands of a hydroxy group (3390 cm-1), of the CO group of an ~,8unsaturated ester (1690, 1290 cm-1), and of the C:==C bonds of a benzene ring (1615, 1600, 1525 cm-Z). A direct comparison of the IR and NMR spectra of substance (I) and those of £-chimgin showed their identity.
The pharmacognostic study of the aerial part of Prangos ferulacea lindl. at the stage of the beginning of vegetation Aim. To study the coumarin composition of salted Prangos ferulacea herb collected at the stage of vegetation and compare it with the coumarin composition of the freshly collected raw material.Materials and methods. The analysis was performed using Agilent 5977 GC and 7890B MS devices. The carrier gas was helium with a constant flow of 1 ml/min. The data of NIST library of standard mass-spectra were used to identify compounds.Results and discussion. The results of the study of coumarin derivatives in the food additive prepared from Prangos ferulacea herb collected at the beginning of the vegetation period are presented. The anatomical structure of the aerial part of Prangos ferulacea has been studied, and the diagnostic features of the plant raw material have been identified.Conclusions. The composition of coumarin derivatives in the food additive and in the freshly collected aerial part is identical. The diagnostic features of the structure of the plant raw material of Prangos ferulacea have been identified.
