The effects of temperature, prechilling, chemicals such as $GA_3$, IAA, kinetin and $KNO_3$ on the germinability of Foeniculum vulgare seed of medicinal plant were examined. In Foeniculum vulgare, the germination rate appeared to be around 50~60% or more in general, showing no differences in germination rate with different temperatures, promoting substances, physical or chemical treatments, and prechilling treatments. The observation of embryo under stereoscopic microscope for Foeniculum vulgare in Umbelliferae showed that seeds with or without embryo was almost the same in number. This result suggests that the lower rate of germination in this species is caused by embryolessness of seeds. The straight-shaped embryos as well as Y-shaped embryos were also observed. Foeniculum vulgare of medicinal plants in Umbelliferae were observed under scanning electron microscope, and did not show any opening problem near micropyle area. Final count should be made on 7th day of germination test.

We investigated the anti-obesity effects of Foeniculum fructus water extract on body weight, epididymal adipocyte size, plasma lipid levels and activities of key enzymes such as lipoprotein lipase (LPL), acyl-CoA synthetase (ACS) in high fat diet-induced obese mice. Experimental groups were normal diet group (ND), high fat diet group (HFD), high fat diet with 0.05% orlistat group (HFDO), and high fat diet with 0.5% Foeniculum fructus group (HFDF). Eleven-weeks feeding with HFD resulted in significant increase in lipid levels, body weight, liver and epididymal adipose tissue weight, compared with the ND group. Diet containing Foeniculum fructus water extract significantly reduced plasma total cholesterol, triglyceride and glucose concentrations as well as body weight, liver and epididymal adipose tissue weights. Plasma LDL cholesterol levels were significantly lower in the HFDF group than those in HFDO group. LPL activities elevated by a high fat diet were significantly decreased by Foeniculum fructus water extract administration. ACS activities decreased in the high fat diet group and markedly increased in the Foeniculum fructus water extract administered group. All things considered, Foeniculum fructus water extract efficiently inhibits the inflow of fatty acid into the cell, and activates metabolic process that uses fatty acids flowing as an energy source. Thus, Foeniculum fructus water extract may have great potential as a novel anti-obesity agent.

The anticoagulant properties of compounds derived from fennel (Foeniculum vulgare Gaertner) fruits were evaluated using a platelet aggregometer and compared with aspirin. The active constituents of fennel fruits were isolated and identified as (+)-fenchone and extragole by various spectral analysis techniques. With regard to the 50% inhibitory concentration ($IC_{50}$), (+)-fenchone effectively inhibited platelet aggregation induced by treatment with collagen ($IC_{50}$, $3.9\;{\mu}M$) and arachidonic acid (AA) ($IC_{50}$, $27.1\;{\mu}M$), and estragole inhibited collagen-induced platelet aggregation ($IC_{50}$, $4.7\;{\mu}M$). By way of comparison, (+)-fenchone and estragole proved to be significantly more potent than aspirin at inhibiting platelet aggregation induced by collagen. The inhibitory activity of (+)-fenchone toward platelet aggregation induced by AA was 1.3 times stronger than that of aspirin. These results indicate that (+)- fenchone and estragole may be useful as lead compounds for inhibiting platelet aggregation induced by arachidonic acid and collagen.

Background: Fusarium oxysporum (F. oxysporum) is the primary pathogenic fungus that causes Panax notoginseng (P. notoginseng) root rot disease. To control the disease, safe and efficient antifungal pesticides must currently be developed. Methods: In this study, we prepared and characterized a nanoemulsion of Foeniculum vulgare essential oil (Ne-FvEO) using ultrasonic technology and evaluated its stability. Traditional Foeniculum vulgare essential oil (T-FvEO) was prepared simultaneously with 1/1000 Tween-80 and 20/1000 dimethyl sulfoxide (DMSO). The effects and inhibitory mechanism of Ne-FvEO and T-FvEO in F. oxysporum were investigated through combined transcriptome and metabolome analyses. Results: Results showed that the minimum inhibitory concentration (MIC) of Ne-FvEO decreased from 3.65 mg/mL to 0.35 mg/mL, and its bioavailability increased by 10-fold. The results of gas chromatography/mass spectrometry (GC/MS) showed that T-FvEO did not contain a high content of estragole compared to Foeniculum vulgare essential oil (FvEO) and Ne-FvEO. Combined metabolome and transcriptome analysis showed that both emulsions inhibited the growth and development of F. oxysporum through the synthesis of the cell wall and cell membrane, energy metabolism, and genetic information of F. oxysporum mycelium. Ne-FvEO also inhibited the expression of 2-oxoglutarate dehydrogenase and isocitrate dehydrogenase and reduced the content of 2-oxoglutarate, which inhibited the germination of spores. Conclusion: Our findings suggest that Ne-FvEO effectively inhibited the growth of F. oxysporum in P. notoginseng in vivo. The findings contribute to our comprehension of the antifungal mechanism of essential oils (EOs) and lay the groundwork for the creation of plant-derived antifungal medicines.

Alzheimer's disease is a neurodegenerative disorder associated with a decline in cognitive abilities. Dementia is one of the aged related mental problems and a characteristic symptom of Alzheimer's disease. Nootropic agents like piracetam and cholinesterase inhibitors like $Donepezil^{\circledR}$ are used in situations where there is organic disorder in learning abilities, but the resulting side-effects associated with these agents have limited their utility. Foeniculum (F.) vulgare Linn. is widely used in Indian traditional systems of medicines and also as a house remedy for nervous debility. The present work was undertaken to assess the potential of F. vulgare as a nootropic and anti-cholinesterase agent in mice. Exteroceptive behavioral models such as Elevated plus maze and Passive avoidance paradigm were employed to assess short term and long term memory in mice. To delineate the possible mechanism through which F. vulgare elicits the anti-amnesic effects, its influence on central cholinergic activity was studied by estimating the whole brain acetylcholinesterase activity. Pretreatment of methanolic extract of fruits of F. vulgare Linn. for 8 successive days, ameliorated the amnesic effect of scopolamine (0.4 mg/kg) and aging induced memory deficits in mice. F. vulgare extract significantly decreased transfer latencies of young mice and aged mice, increased step down latency and exhibited significant anti-acetyl cholinesterase effects, when compared to piracetam, scopolamine and control groups of mice. F. vulgare might prove to be a useful memory restorative agent in the treatment of dementia seen in the elderly.

이물질 침입에 대한 인식의 결과 NO, PGE$_2$, TNF-, IL-6와 같은 여러 신호전달물질의 분비가 개시되며 이들을 억제하는 물질을 항염증제라고 볼 수 있다. 본 연구에서는 회향(Foeniculum vulgare Mill.) 열매 추출물이 mouse macrophages RAW264.7 세포에서 lipopolysaccharide(LPS)로 유도한 NO(iNOS 산물), PGE$_2$(COX-2 산물) 및 cytokines (TNF-$\alpha$, IL-6) 생성 억제에 미치는 영향을 살펴보았다. 회향 열매의 methanol 추출물 및 분획물(chloroform, butanol, and aqueous fractions)은 4～100$\mu$g/mL 농도에서 LPS가 활성화된 대식 세포에서 NO 생성을 억제하였으며 독성을 나타내지 않았다. LPS가 유도한 PGE$_2$ 생성은 butanol 분획(100 $\mu$g/mL)에 의해서만 유의적으로 감소하였다(P<0.05). 회향 열매 추출물 및 분획물은 TNF-$\alpha$의 생성을 유의적으로 감소시켰으며 IL-6의 생성은 methanol extract(4～100 $\mu$g/mL), chloroform fraction(4 $\mu$g/mL), butanol fraction(4 and 100$\mu$g/mL) 및 aqueous fraction(4～100 $\mu$g/mL)에 의해 감소되었다(P<0.05). 이는 회향 열매 추출물은 염증 상태에서 유용할 것이며 COX-2와 iNOS를 억제하는 butanol 분획은 새로운 항염증제 개발에 사용될 수 있음을 시사하여 주었다.

The various plant organs of fennel (Foeniculum vulgare Mill.) were investigated to identify their volatile components using Dynamic Headspace (purge & trap). They showed slight differences concerning the volatile components both qualitatively and quantitatively. Results revealed that trans-anethole (12.65%) was the major compound in the leaf. The highest compound was ${\alpha}-pinene$ (28.78%), and trans-anethole (7.90%) was highly detected in the stem. The maximum values were 5.64, 4.59, 1.58, 1.51, and 1.04% for ${\alpha}-pinene,\;{\gamma}-terpinene,\;{\beta}-pinene$, 1,8-cineol and fenchone, respectively in the flower. However, very little trans-anethole was detected (0.27%) in the flower. From these results, it was suggested that the major components were different depending on the plant organs. However it was demonstrated that the related plant organs like flower-fruit and leaf-stem contained the similar components.

Polysaccharides were isolated with alkaline extraction method from twelve pharmaceutical plants, which have been used against the various tumors in the oriental herb medicine, and examined for their antitumor activities. When the polysaccharides were administered i. p. at the dose of 10mg/kg/day for ten consecutive days to the male ICR mice, which had been implanted with $1{\times}10^{6}$ cells of sarcoma 180 twentyfour hours before the first injection of polysaccharides, those from Forsythia Corea, Curcuma, Zedoaria, Albizzia Julibrissin, Prunuts Persica, Foeniculum Vlugare and Daphne Pseudogenkwa showed inhibition ratios of 88.0%, 61.1%m 73.0%, 72.8% 55.1% and 71.7%. The significant prolongation of life span was observed only in the case of Forsythia Corea (18.1%). Other six polysaccharide fractions from Olibanum, Lonicera Japonica, Rheum Coreanum, Scirpus Maritimus, Gleditchia Officinalis and Brassica Juncea showed negligible inhibition ratios.
