Öğe Comparing the effect of sub-critical water extraction with conventional extraction methods on the chemical composition of Lavandula stoechas(Elsevier Science Bv, 2008) Giray, E. Sultan; Kirici, Saliha; Kaya, D. Alpaslan; Turk, Murat; Sonmez, Ozgur; Inan, MemetThe volatile extract composition of Lavandula stoechas flowers obtained by hydrodistillation (HD), subcrtical water extraction (SbCWE) and organic solvent extraction under ultrasonic irradiation (USE) were estimated by gas chromatography-mass spectrometry (GC-MS). One hundred and twenty four components were detected in SbCWE extracts while 94 and 65 signals were gained from HD and USE extracts, respectively. Most of the constituents were identified. The major compounds in all three extracts were fenchon, camphor, myrtenyl acetate, myrtenol and 1,8-cineol, but they differ in quantitatively. The total monoterpene hydrocarbons are higher in HD and USE extracts than those of SbCWE extract. However, SbCWE extract had higher concentration of light oxygenated compounds which contributes to the fragrance of the oil in a major extension. Heavy-oxygenated compounds was also in higher abundance in SbCWE extract (9.90%) than those of HD and USE extracts (3.19 and 4.78%, respectively). Effect of temperature on the extraction yield of SbCWE was investigated and while oil yield was increasing with an increase in temperature, a decrease in the extraction ability of sub-critical water toward the more polar compounds such as, 1,8-cineol, camphor and fenchon, was observed. Kinetic studies shown that SbCWE is clearly quicker than conventional alternatives. Most of components of volatile compounds were extracted at 15 min. (C) 2007 Elsevier B.V.

Lavandula stoechas ssp. stoechas which is called Karabasotu in Turkish, has grown commonly under the natural conditions of Turkey. This species is widely used in cosmetics as well as for medicinal use. Seeds of this species collected from Hatay were domesticated at the field trial area of Cukurova University Agricultural Faculty. Plants were harvested three times a day (07:(00)am, 12:(00)am and 05:(00)pm) during two different growing stages (before flowering and full flowering). Contents of essential oil and its components were determined by using bottom, middle and top leaves for both growing stages in each harvest time. In addition to the three plant parts, the flower part was used at full flowering stages. The content of essential oils ranged between 0.71-1.97% and alpha-pinene, d-fenchone, camphor, eucalyptol, and myrtenyl-acetate were determined as major essential oil components depending on plant parts, growing stages and harvesting times.Öğe Diurnal, ontogeneticand morphogenetic variability of lavandula stoechas L. ssp. stoechas in East Mediterranean Region(Syscom 18 SRL, 2012) Kaya, Durmus Alpaslan; Inan, Memet; Giray, Elife Sultan; Kirici, SalihaLavandula species which belong to Lamiaceae family have a wide spread area in the Mediterranean region.

In order to measure fastness degree of wool dyed with these plants, dying were made by using mordant of alum. So, plant organs crushed at the weight of 25%, 50%, 100% and 200% of wool weight were used. Dark colors were determined at all samples with which plant two times of wool weight were used. However, as dye concentration increased, rubbing and washing fastness in wools decreased; whereas wet water dropping fastness increased. Dry water dropping fastness obtained from all concentration were found to be high (4-5).Öğe Effect of harvest time on essential oil composition of thymbra spicata L. growing in flora of adıyaman(American-Eurasian Network for Scientific Information, 2011) Inan, Memet; Kirpik, Muzaffer; Kaya, D. Alpaslan; Kirici, SalihaThymbra spicata L. is an aromatic shrub growing wild in different regions of Turkey. This plant has traditionally been used for different purposes by local settlements. Leaves of Thymbra spicata were collected from Kahta district of Adi{dotless}yaman (684 m, 370 43' N, 380 39' E) in three different harvest time as follows: before flowering (10 May 2010), in flowering (21 May 2010) and after flowering stage (10 June 2010). Essential oil contents of the plant samples were determined by Hydro-distillation in Clevenger Apparatus with three hours. Composition of the essential oils was determined by Gas Chromatography Mass Spectrometry (GC-MS). All the laboratory analysis was performed with three replications. In conclusion, the highest and the lowest essential oil contents of Thymbra spicata were obtained from the full blooming harvests (3,56%) and after flowering (3,38%), respectively. The lowest essential oil content was found in before flowering harvest (3,10%). Besides essential oil contents, essential oil composition of Thymbra spicata was also affected by different harvest times.Öğe The effects of different nitrogen doses on Artemisia annua L.(2002) Ayanoglu, Filiz; Mert, Ahmet; Kirici, SalihaThe purpose of this study was to determine the effects of different nitrogen doses (0, 6, 12 and 18 kg/da) on the plant parameters, yields and quality of Artemisia annua L. ecotype from Adana, Turkey. A two-year experiment was conducted between 1996-1998 under Adana ecological conditions. During this study, plant height (cm), number of branches per plant, fresh herb yield (kg/da), dry herb yield (kg/da), dry leaf yield (kg/da), essential oil content (%) essential oil yield (1/da), artemisinin content (%), and artemisinin yield (kg/da) were investigated, The results indicated that application of different N doses statistically affected the essential oil content and oil yield only the first year of the study. But artemisinin content and yield were not significantly affected. © 2002 by The Haworth Press, Inc.

In the study, the plant height (cm), fresh weight (kg/da), dry weight (kg/da), dry leaf weight (kg/da), essential oil content (%), essential oil yield (1/da), artemisinin content (%), and artemisinin yield (kg/da) of ecotypes were investigated. The results of this study showed that the highest essential oil content and the highest essential oil yield were found in the Samankaya ecotype when planted at 15 plants/m2. However, the highest artemisinin content and highest artemisinin yield were found in the Serinyol ecotype when planted at 15 plants/m2. © 2002 by The Haworth Press, Inc.

IN CUKUROVA REGION(Incdtp-Icpi, 2010) Kaya, Durmus Alpaslan; Kirici, Saliha; Giray, Elife Sultan; Inan, MemetThis study has been carried out to determine yield and quality of valerian essential oil grown in Cukurova region. Valerian seeds cultivars were acquired from Germany (Anton and Mehrfahrig). It has been determined that Valeriana officinalis L. could be grown easily in Cukurova region. The essential oil of subterranean parts of valerian was obtained by hydrodistillation (0,95-1,03%) and analyzed by GC-MS. The main characteristic of V. officinalis essential oil was isopren (1.8%), monoterpenoids (19.9%), sesquiterpenoid (10.1%), light oxygenated compounds (30.7%) and heavy oxygenated compounds (37.5%). The major compounds in the essential oil of both cultivars were bornyl acetate, valerenal, camphene, spathulenol and fenchene.Öğe Essential oil composition of cultivated valerian (Valeriana officinalis L.) in Cukurova Region(2010) Kaya, Durmus Alpaslan; Kirici, Saliha; Giray, Elife Sultan; Inan, MemetThis study has been carried out to determine yield and quality of valerian essential oil grown in Cukurova region.
