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...

We study electron transfer (ET) in a two level quantum system coupled to a glassy viscous bath. The bath is modeled by the Cole-Davidson (CD) spectral density. The ET in this model is compared to the ET in a normal Drude-Debye (DD) model. It is shown that at low temperatures and when the coupling to the bath is weak, the viscous bath preserves the quantum coherence for a longer time. However in...

17 Road verges have been proposed as refuges for vulnerable grassland species in the 18 modern, changing landscape, but little comparative knowledge exists on how 19 management regimes affect population dynamics of such species. We compared the 20 effects of various management regimes on population dynamics of Pimpinella saxifraga 21 in road verges and pastures, using elasticities and LTRE-anal...

Antibacterial activity of crude extracts of culinary spices like Aniseed (Pimpinella anisum), Star anise (Illicum verum Hook fruit) and Cinnamon (Cinnamomum zeylanicum) against some of the common fish bacterial pathogens like Aeromonas hydrophila, Aeromonas salmonicida and Edwardsiella tarda were explored by finding minimum inhibitory concentration (MIC). A twofold serial dilution of compounds ...

Background: Buceng is a combination of plant of purwoceng (Pimpinella alpina Molk) and pasak bumi (Eurycomalongifolia Jack) that has been traditionally used to enhance adult male vitality. However, the mechanism of action of buceng has not been understood. This study was aimed to elucidate whether buceng could increasing Testosterone (Te), Luteinizing Hormone (LH), and Follicle Stimulating Horm...
