The essential oil of the root of Heracleum persicum (Apiaceae) was analyzed by capillary GC and GC /MS. The major constituents were identified as viridiflorol (23.05 %), elemol (3.63 %), b-maliene (3.07 %), spathulenol (3.34 %) and 2-tetradecanol (3.38 %).

We present an extension, for nonlinear optimization under linear constraints, of an algorithm for quadratic programming using a trust region idea introduced by Ye and Tse [Math. Programming, 44 (1989), pp. 157–179] and extended by Bonnans and Bouhtou [RAIRO Rech. Opér., 29 (1995), pp. 195–217]. Due to the nonlinearity of the cost, we use a linesearch in order to reduce the step if necessary. We...

two flavones, ladanein and 6-hydroxy-5,7,4′-trimethoxyflavone and one labdane-typediterpene, ent-13-epi-manoyloxide, were isolated from an ethyl acetate-methanol extract ofthe aerial parts of salvia sharifii. the compounds were purified using several chromatographicmethods. structural elucidation of the compounds was performed using their 1h and 13c-nmrdata, ei mass and uv spectral data. the co...

Fragrant species of the genus Salvia have been attributed many medicinal properties, which include anticancer activity. In the present study, cytotoxic properties of total methanol extract of Salvia chloroleuca Rech. f. & Aellen and its fractions were investigated on MCF- 7, a breast carcinoma cell line. Malignant and non-malignant cells were cultured in RPMI medium and incubated with different...

The biological activity and composition of the essential oil of Sclerorhachis leptoclada Rech. f. an endemic species from northeast of Iran was studied. The essential oil was isolated from the aerial flowering parts of the plant and analyzed by GC and GC-MS. Fifty-four compounds accounting for 95.9% of the total oil were characterized. The main constituents were (E)-nerolidol (14.5%), terpinen-...

Medicinal plants have long been considered for the treatment of many diseases among Iranians and in recent years use medicinal has increased. In traditional Iranian medicine, described to eliminate kidney stones, dissolve stones or prevent stone formation. Based on results Cichorium intybus L. Biarum straussii Engl., Tribulus terrestris L., Nasturtium officinale R. Br., Alhagi camelorum Fisch.,...

objective: this study was designed to investigate the effect of hydroalcoholic extract and essential oil of heracleum persicum (apiaceae) on lipid profile of male hyperlipidemic rabbits. materials and methods: thirty rabbits were randomly divided into six groups of five each. one group received normal diet and the other groups fed with a high cholesterol (2% w/w) diet for 7 weeks. vehicle, hydr...

conclusions results of this study suggest that the extract alone of peganum harmala and heracleum persicum may be useful to treat bacterial infections. objectives the major aim of the current study was to investigate the antimicrobial activity of an extract of the peganum harmala flower and heracleum persicum against acinetobacter baumannii. materials and methods the minimum inhibitory (mic) co...
