Tissue cultures o f Pimpinella anisum and P. major were used to study the biosynthesis o f pseudoisoeugenols. The putative precursors were labelled with 13C with one exception that was labelled with i4C. The incorporation o f the label was controlled by 13C N M R and liquid scintil lation, respectively. The biosynthetic sequence found was L-phenylalanine, /-cinnamic acid, /?-coumaric acid, / 7...
Background and Aim: It is believed that cortical spreading depression (CSD) is underlying mechanism of aura and subsequent pain in migraine. This study was designed to investigate the effect of Pimpinella Anisum on CSD specifications in rat neocortical slices. Materials and Methods: In this experimental study, CSD was induced in rat somatosensory cortical slices using two methods. At the firs...
The plant species Pimpinella serbica (Vis.) Drude, endemic to West Balkans, belongs the genus L. (Apiaceae) according newer botanical classification. Initially, was described as Pancicia Vis. and long considered a monotypic genus. Previous phytochemical investigations of this were limited essential oil analysis by GC?MS method. This is first study that includes LC-DAD?MS screening extracts root...
جنس Pimpinella در ایران حدود 20 گونه دارد که اغلب یکساله می باشند. از رایج ترین گونه های چند ساله P. aurea و P. tragium می باشند که تقریبا در سراسر مناطق معتدله سرد ایران پراکنده اند. یکی از گونه های بسیار معطراین جنس P. anisum است که ارزش صادراتی بسیاری دارد.یکی از اهداف این طرح بررسی سایر گونه های این جنس از جهت تولید اسانس است. گیاه P. aureaدر مرحله گلدهی و بذردهی از دو منطقه ( فشم و توچال...
Anisaldehyde characterized in the seeds of Pimpinella anisum L. (Umbelliferae), also known as aniseed, was found to inhibit the oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) by mushroom tyrosinase (EC 1.14.18.1) with an ID50 of 43 μg/mL (0.32 mM). The inhibition kinetics analyzed by a Lineweaver-Burk plot established anisaldehyde to be a noncompetitive inhibitor for this oxidation. On the ...
The species of Pimpinella, one the largest genera family Apiaceae, are traditionally cultivated for medicinal purposes. In this study, high-throughput double digest restriction-site associated DNA sequencing technology (ddRAD-seq) was used to identify single nucleotide polymorphisms (SNPs) in eight Pimpinella from Iran. After double-digestion with enzymes HpyCH4IV and HinfI, a total 334,702,966...
No Brasil, o consumo de chás a base plantas medicinais e fitoterápicas advém do conhecimento empírico da população acerca dos benefícios uso cada espécie. Dentre os mais comercializados no Brasil estão as duas espécies conhecidas erva doce, Pimpinella anisum Foeniculum vulgare, utilizadas não apenas pelo seu efeito ansiolítico, mas também pelos seus controle sintomas climatério.
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...
The efficacy of methanolic extracts and powders of 12 spices (Pimpinella anisum, Scorodophleuszenkeii, Xylopiaparviflora, Eugenia caryophyllus, Fagara leprieurii, Fagara macrophylla, Monodora myristica, Olax subscorpioidea, Xylopiaaethiopica, Allium sativum, Zinziber officinale and Cinnamomum zeylanicum) in stabilizing crude soyabean oil during accelerated storage was assessed. The phytochemica...
