A rotationally fluid state of α-pinene at fused silica/vapor interfaces is revealed by computational and experimental vibrational sum frequency generation (SFG) studies. We report the first assignment of the vibrational modes in the notoriously congested C−H stretching region of α-pinene and identify its bridge methylene group on the four-membered ring (“CH2”) as the origin of its dominant spec...

background & aim: turmeric, scientifically named (curcuma longa l.), a member of ginger (zingiberaceae) family, is a perennial plant, with pharmaceutical properties and with a rhizome. this plant has many medicinal characteristics including anti-cancer, anti-bacteria and anti-hepatitis properties. experimental: to study the effects of gibberellic acid and salicylic acid on leaf, the rhizome...

Rosmarinus officinalis L. (synonym Salvia rosmarinus Schleid) grows in the Mediterranean basin and is known to be a source of natural bioactive compounds one most important aromatic species terms marketing essential oil. However, wild collection lack selection lead absence standardized material that ensures homogeneity quality oils over time. In present work, thirteen Spanish populations rosema...

the leaves of four cultivated eucalyptus species, eucalyptus microtheca var. microtheca f. muell., eucalyptus spathulata, eucalyptus largiflorens and eucalyptus torquata were collected in spring from kashan and isfahan provinces (central region of iran). after drying the plant materials in shade, their essential oils were obtained by hydro-distillation. the oils were analyzed by capillary gas c...

A simple, accurate and precise HPTLC method was developed validated for simultaneous estimation of 1, 8-Cineole Betulinic acid in Shati Vati - An Ayurvedic formulation by HPTLC. contains rhizome powder have 1-8 cineole Badar ripe fruit reported medicinal claims uses. In the analytical method, toluene: ethyl acetate (93:07 v/v) finalized as mobile phase a clear separation achieved. The wavelengt...

The essential oils of the flowers, leaves and stems of Senecio polyanthemoides Sch. Bip. Samples collected from two different localities within the city of uMhlathuze, KwaZulu-Natal Province (South Africa) were isolated by hydrodistillation and analyzed using GC and GC/MS. Twenty-six constituents were identified, representing an average of 86.0 - 99.6% of the total oil composition. The chemical...
