Larvae and adults of certain species of predator lady beetles feed on pollen, guaranteeing their survival, and at times, reproduction in the absence of preferred prey. Palynology, therefore, may contribute in the investigation of botanical families visited by these predators in order to obtain this floral resource. There are records of the visitation of Apiaceae flowers by Coleomegilla maculata...

Ruta graveolens (rue) is a spontaneous plant in the Mediterranean area with a strong aroma and a very intense bitter taste, used in gastronomy and in folk medicine. From the leaves, stems and fruits of rue, we isolated rutin, rutamarin, three furanocoumarins, two quinolinic alkaloids, a dicoumarin and two long chain ketones. Bitter taste and chemesthetic properties have been evaluated by in vit...

Phylogenetic relationships among 25 members of Apiaceae (Umbelliferae) subfamily Apioideae, representing 7 of the 8 tribes and 8 of the 10 subtribes traditionally recognized in the subfamily, and 5 outgroups from Apiaceae subfamilies Hydrocotyloideae and Saniculoideae and allied families Araliaceae and Pittosporaceae have been inferred from nucleotide sequence variation in the intron of the chl...

گلپر (heracleum) گیاهی چند ساله، متعلق به تیره چتریان (apiaceae) و بومی مناطق شمالی ایران می باشد. در ایران هشت گونه گلپر یافت می شود که سه گونه آن بومی کشور ما می باشد. گیاه گلپر دارای ارزش اقتصادی و دارویی می باشد. یکی از مشکلات عمده این گیاه دارویی عدم جوانه زنی مطلوب بذرهای آن در شرایط آزمایشگاهی و برداشت بی رویه آن در رویشگاه های طبیعی است. در بخش اول این پژوهش، هدف بررسی اثر عوامل شیمیایی...

By using a cell-based high throughput screening campaign, a novel angelicin derivative 6a was identified to inhibit influenza A (H1N1) virus induced cytopathic effect in Madin-Darby canine kidney cell culture in low micromolar range. Detailed structure-activity relationship studies of 6a revealed that the angelicin scaffold is essential for activity in pharmacophore B, while meta-substituted ph...

Cells from patients with the inherited disorder, Fanconi's anemia (FA), were analyzed for endonucleases which recognize DNA interstrand cross-links and monoadducts produced by psoralen plus UVA irradiation. Two chromatin-associated DNA endonuclease activities, defective in their ability to incise DNA-containing adducts produced by psoralen plus UVA light, have been identified and isolated in nu...

Two new diterpenes, named sibiriquinone A (1) and B (2), along with four known diterpenes have been isolated from the aerial part of Veronicastrum sibiricum. Their structures were elucidated by spectroscopy. The isolated compounds showed significant immunosuppressive activities.
