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.

In this study we sought to elucidate the therapeutic effects of fenchone on constipation-predominant irritable bowel syndrome (IBS-C) and the underlying mechanisms. An IBS-C model was established in rats by administration of ice water by gavage for 14 days. Fenchone increased the reduced body weight, number of fecal pellets, fecal moisture, and intestinal transit rate, and decreased the enhanced visceral hypersensitivity in the rat model of IBS-C. In addition, fenchone increased the serum content of excitatory neurotransmitters and decreased the serum content of inhibitory neurotransmitters in the IBS-C rat model. Meanwhile, western blot and immunofluorescence experiments indicated that fenchone increased the expressions of SCF and c-Kit. Furthermore, compared with the IBS-C model group, fenchone increased the relative abundance of Lactobacillus, Blautia, Allobaculum, Subdoligranulum, and Ruminococcaceae_UCG-008, and reduced the relative abundance of Bacteroides, Enterococcus, Alistipes, and Escherichia-Shigella on the genus level. Overall, fenchone ameliorates IBS-C via modulation of the SCF/c-Kit pathway and gut microbiota, and could therefore serve as a novel drug candidate against IBS-C.

소나무과 식물(곰솔, 리기다소나무 및 소나무)이 지닌 monoterpene의 표준시약 12가지를 4가지 농도별로 Escherichia coli와 Aspergillus nidulans에 처리하여 성장 저해 효과를 조사하였다. E. coli의 성장 저해 효과가 있는 것들은 (R)(-)carvone, (S)(+)carvone, (1R)(-)fenchone, (-)menthone, α-pinene, (1S)(-)verbenone 그리고 (+)β-pinene이었고, 이들 중에서 가장 높은 성장 저해 효과를 보이는 것은 (+)β-pinene이었다. 그리고 A. nidulans에 성장 저해 효과를 보이는 것들은 (R)(-)carvone, (S)(+)carvone, (+)β-pinene, geranyl-acetate, α-pinene 그리고 (1S)(-)verbenone이었다. 본 실험에서 A. nidulans에 성 장 저해 효과를 나타내는 monoterpene은 대부분 E. coli에서도 저해효과를 보이는데, 다만 geranyl-acetate는 E. coli에서는 전혀 영향을 미치지 않는 것으로 나타났다. 또한 (1R)(-)fenchone과 (-)menthone은 E. coli의 성장 억제를 하는 반면. A. nidulans의 성장에는 영향이 없었다. 특히 주목할 만한 점은 myrcene, sabinene, bornyl acetate 그리고 limonene의 경우 두 종 모두에서 성장 저해 효과가 전혀 나타나지 않았다.

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.

The monoterpenoids are analysed in leaves and fallen leaves of Pinus species (P. thunbergii, P.. rigida. P. densiflora.). The amount of total monoterpenoids of P. thunbergii was always the highest, and then those of P. rigida and P. densiflora were orderly decreasing (P<0.05). The major monoterpenoids of P. thunbergii, P. rigida and P. densiflora are ${\beta}-pinene$, comphene and sabinene. There was no significant difference among the seasonal variation in monoterpenoids composition (P>0.05), but the concentrations of fenchone and bornyl acetate were varied (P<0.05).

The fruits of Foeniculum vulgare (Foeniculi Fructus) have been widely used in Chinese medicine as an antiemetic, ameliorating stomach ailments and as an analgesic. In order to establish its potential for antiallergic use, inhibitory actions of the fruit on 5-lipoxgenase (5-LOX) and ${\beta}$-hexosaminidase release were evaluated. The 70% ethanol extract of this plant material (FR) considerably inhibited 5-LOX-catalyzed leukotriene production from A23187-induced rat basophilic leukemia (RBL)-1 cells. The $IC_{50}$ was $3.2{\mu}g/ml$. From this extract, 12 major compounds including sabinene, fenchone, ${\gamma}$-terpinene, ${\alpha}$-pinene, limonene, p-anisylacetone, panisylaldehyde, estragole (4-allylanisole), trans-anethole, scopoletin, bergapten and umbelliferone were isolated. And it was found that several terpene derivatives including ${\gamma}$-terpinene and fenchone as well as phenylpropanoid, trans-anethole, showed considerable inhibitory action of 5-LOX. In particular, the $IC_{50}$ of trans-anethole was $51.6{\mu}M$. In contrast, FR and the isolated compounds did not show considerable inhibitory activity on the degranulation reaction of ${\beta}$-hexosaminidase release from antigen-treated RBL-2H3 cells. Against arachidonic acid-induced ear edema in mice, FR and trans-anethole showed significant inhibition by oral administration at doses of 100-400 mg/kg. In conclusion, FR and several major constituents are 5-LOX inhibitors and they may have potential for treating 5-LOX-related disorders.

The total monoterpenoid content of the pine litter layer and the availability of these compounds as inhibitors/stimulators on Polysphondylium violaceum of cellular slime molds were investigated. In order to determine the several monoterpenoids in the natural environment, we examined their concentrations in fresh, senescent, and decaying needles from 3 pine species (Pinus densiflora, P. thunbergii, P. rigida) by litter bag method. Total monoterpenoid content was highest in the fresh needles, but also remained relatively high in senescent needles. The effect of monoterpenoids identified from Pinus plants on the growth of P. violaceum was studied. We tested four concentrations (1, 0.1, 0.01, and $0.001\;{\mu}g/{\mu}L$) of each compound by using a disk volatilization technique. Each compound was treated after germination of spores of P. violaceum. All of the compounds at $1\;{\mu}g/{\mu}L$ concentration had a very strong inhibitory effect on cell growth of P. violaceum. Fenchone at all concentrations, myrcene, verbenone, bornyl acetate, and limonene at low concentrations stimulated the growth of P. violaceum. These results suggest that inhibitory or enhancing effects of selected monoterpenoids depend upon the concentration of the individual compound.
