Effects of manure, chemical fertilizer and plant density on hypericin content of Hypericum perforatum
Volume 10, Issue 1 , November 2001, , Pages 39-64
Abstract
Fluctuation of hypericin and yield in Hypericum perforatum was examined in Karaj Research Station in 1989. In this study chemical fertilizer, organic manure and combination of them were allocated in subplot, and plant density was allocated as main plot with 4,5.7 and 10 plant m?. In a split plot design ... Read MoreComposition of the essential oil of fruit and aerial parts of Petroselinum sativum
Volume 9, Issue 1 , August 2001, , Pages 163-177
Abstract
The herb was cultivated in the Research Station of Alborz-Karaj. Essential oils were extracted from aerial parts of plants at full flowering stage by steam distillation and by water distillation from fruit. The oil content were 1.3% in the aerial parts of plant and 2.5% in the fruit. Concentration and ... Read MoreCompositition of the Essential oil from Carum carvi Grown in Ardebil
Volume 8, Issue 1 , July 2001, , Pages 121-133
Abstract
Fruit of Carum carvi L. was collected from Ardebil province (Aparchai region) in August 1997. The essential oil of crashed fruit was obtained by water distillation method for 4 hours (R=5.5% w/w). The oil was analysed by GC/MS. Result of it showed 11 components above 0.2% concentration in essential ... Read MoreComparative study of the essential oil composition of Satureja hortensis L. by hydro and steam distillation methods
Volume 7, Issue 1 , April 2001, , Pages 55-70
Abstract
Essential oil of Satureja hortensis was isolated from shoots at flowering stage by two steam and hydrodistillation methods. Both of essential oil were analysed by GC-MS. Twenty-six components were identified representing 99.6% of the oils. The major components being y-terpinene (38%, 47%), Carvacrol ...

Volume 7, Issue 1 , April 2001, , Pages 89-100
Abstract
The seed of Cuminium cyminium was produced by dry farming at 4 separate planting dates (Feb. to Mar. with 10 day interval), in Kerman province (Sirch region). Then the seeds were harvested in June. The essential oils of seeds was isolated by Clevenger apparatus to produce the oil in A=1.5%, B=3.4%, ... Read MoreComparison of Ephedrine and Pseuduephedrine contents in Ephedra species in Iran
Volume 6, Issue 1 , September 2000, , Pages 48-65
Abstract
A total of 42 Ephedra herba samples which belong to 9 species of Epedra, were collected from extraction of total Alkcloids, contents of two Ephedra, Alkoloid cephedrine and Psudoephedra) Were determined by GC/MS. Generally E. major was superior (0.1-1.8) and E. brevifoliata (0.05-0.08) and E. foliate ... Read MoreStudie on Chemical composition of the Essential Oil from seeds of Cuminum cyminum L.
