Acute toxicities of 34 naturally occurring monoterpenoids were evaluated against 3 important arthropod pest species; the larva of the western corn rootworm, Diabrotica virgifera virgifera LeConte; the adult of the twospotted spider mite. Tetranychus urticae Koch; and the adult house fly. Musca domestica L. Potential larvicidal or acaricidal activities of each monoterpenoid were determined by to...
جنس Dracocephalum از تیره نعناعیان در ایران 8 گونه علفی یکساله و چند ساله معطر دارد که گونه D. kotschy یکی از گونههای انحصاری این جنس در ایران محسوب میشود. سرشاخههای گلدار این گیاه از اطراف تونل کندوان در ارتفاع 2600 متری جمعآوری شد و اسانس آن به روش تقطیر با بخار آب با بازده 0.5% (برحسب وزن خشک) استخراج شد. تجزیه و تحلیل اسانس با استفاده از دستگاه GC/MS و GC نشان داد که ترکیبهای (38.2%) Li...
Twenty naturally occurring monoterpenoids were evaluated in a preliminary fumigation screening test on some important stored-product pest insects, including the rice weevil, Sitoplzilus oryzae, the red flour beetle, Tribolium castaneum, the sawtoothed grain beetle, 0rj)zaephilus surinamensis, the house fly, Musca dornestica, and the German cockroach, Blattella germanica.

The Michael addition of dibenzylamine to (+)-tert-butyl perillate (3) and to (+)-tert-butyl phellandrate (6), derived from (S)-(-)-perillaldehyde (1), resulted in diastereomeric β-amino esters 7A-D in a moderately stereospecific reaction in a ratio of 76:17:6:1. After separation of the diastereoisomers, the major product, cis isomer 7A, was quantitatively isomerized to the minor component, tran...
The chemical composition of the essential oil of fruits of Pimpinella haussknechtii. was studied by GC-MS. After GC-MS analysis, one unknown component (56.7%) was observed, which was not characterized in the GC-MS library. The essential oil of P.haussknechtii was injected to HPLC using YMC-Pak-Sil column (250 × 20 mm) with gradient system of hexane (A), and hexane: ethyl acetate, 9:1 (B) to yie...
