Essential oil composition of Teucrium scordium L.
Composition of the essential oil obtained from dried flowering aerial parts of Teucrium scordium L. (Labiatae) was analyzed by GC and GC/MS. Fifty-six components were identified in the essential oil of T. scordium. The major constituents of the oil were beta-caryophyllene (22.8%), (E)-beta-farnesene (10.4%), caryophyllene oxide (8.6%), 1,8-cineole (6.1%) and beta-eudesmol (5.1%).
متن کاملEffects of a lectin from Polygonum persicaria L. on Pieris brassicae L. (Lepidoptera: Pieridae)
In the current study, the entomotoxic effects of a lectin, extracted from Polygonum persicaria, were determined on Pieris brassicae larvae. The purified molecule significantly decreased larval survival, weight, and mass protein. Different concentrations of P. persicaria agglutinin (PPA) (0.5, 1 and 2 mg/ml) significantly decreased nutritional indices including: the efficiency of conversion of i...

The volatile profile of H...
متن کاملTeucrium polium L. essential oil: phytochemiacl component and antioxidant properties
The essential oil (EO) obtained by hydrodistillation from Teucrium polium L. was analyzed by gas chromatography and gas chromatography mass spectrometry (GC/MS). Antioxidant activity was evaluated through DPPH assay and Beta-carotene/linoleic acid assay. Twenty one components were identified representing (90.4%) of the EO. Main constituents of the essential oil were found as Spathulenol (15.06%...
متن کاملComposition of the essential oil of Lonicera heterophylla Decne.
Aerial parts of the plant (250 g) were collected during flowering in April 2000 from Tehran province in Iran. The essential oil was obtained by steam distillation of air-dried aerial parts in an all-glass apparatus. The sample oil that was light yellow in color was dried over anhydrous sodium sulfate and stored under nitrogen in a sealed vial until required. The essential oil was examined by GC...
