Sterols were obtained from the non-saponifiable matters of ethereal and methanolic extracts of the root of Panax ginseng. The composition of sterols has been determined by gas chromatographic analysis. It was noted that campesterol, stigmastrol and ${\beta}-sitosterol$ were the major sterols in the ginseng. The results showed that contents of sterols were campesterol, $4.01{\sim}5.82%,\;stigmasterol,\;18.32{\sim}19.12%\;{\beta}-sitosterol,\;and\;75.11{\sim}77.74%$.

The phytochemical study of Cacalia koraiensis Nakai (Compositae) led to the isolation of eight compounds, $\beta$-sitosterol (1), stigmasterol (2), phytol (3), $\beta$-sitosterol-3-Ο-glucopyranoside (4), adenostylol (5), campesterol (6), germacradien-4$\alpha$-ol (7), and quercetin-3-rhamnoside (8). Their structures were established by chemical and spectroscopic methods. The cytotoxicity of the isolated compounds was evaluated by SRB assay against five cultured human tumor cell lines.

To characterize the nutraceutical property of Italian millet (Setaria italica) and sorghum (Sorghum bicolor), ten Korean landraces of each crop were collected and their vitamin E (tocopherols and tocotrienols), squalene and phytosterols (campesterol, stigmasterol and ${\beta}$-sitosterol) contents as well as fatty acid composition in seeds were evaluated. Italian millet seeds exhibited 5 forms of vitamin E isomers: three (${\alpha}$-, ${\gamma}$- and ${\delta}$-) tocopherols and two (${\alpha}$- and ${\gamma}$-) tocotrienols, while sorghum seeds showed only three forms of vitamin E isomers: ${\alpha}$- and ${\gamma}$-tocopherol and ${\alpha}$-tocotrienol. In both crops, ${\gamma}$-tocopherol was the major constituent of vitamin E in terms of highest quantity. Total vitamin E content in Italian millet and sorghum landraces were 88.3 mg/kg and 44.3 mg/kg, respectively. Among three phytosterols (campesterol, stigmasterol and ${\beta}$-sitosterol) analyzed, ${\beta}$-sitosterol was the major form comprising about 85% and 65% in Italian millet and sorghum landraces, respectively. Total phytosterols content ranged from 443.0 to 568.5 mg/kg and 442.3 to 719.2 mg/kg in Italian millet and sorghum, respectively. Squalene, a precursor of phytosterols biosynthesis, ranged from 6.8 to 10.2 mg/kg in Italian millet and from 62.2 to 115.2 mg/kg in sorghum. Linoleic, oleic and palmitic acids were the major fatty acids in both of the crops and about 80% of the total fatty acids were unsaturated fatty acids. Among the tested landraces, M09 and S10 showed relatively higher proportion of phytonutrients, suggesting their potential as a gene source for further breeding program.

본 연구에서는 혈중 콜레스테롤 저하 효과가 알려져 있는 $\beta$-시토스테롤과 지방산과의 에스테르화 반응에 의하여 $\beta$-시토스테롤의 지용성 치환체를 합성하였다. 지방산으로 스테아린산, 올레인산 및 리놀레산을 사용하여 산 촉매 존재 하에서 에스테르화 반응을 수행하였을 때, 불포화지방산인 올레인산 및 리놀레산의 경우에는 불포화기의 산화에 기인하는 것으로 판단되는 부산물이 생성되었다. 반면에 탈수제 및 염기성 촉매의 존재 하에서는 불포화지방산의 경우에도 원하는 치환체를 순수한 형태로 합성할 수 있었다. 생성된 $\beta$-시토스테롤의 지용성 치환체의 유기용매 및 식용유에 대한 용해도는 사용된 지방산의 불포화도가 높을수록 높은 것으로 나타났다.

Background: The Panax ginseng plant is used as an herbal medicine. Phytosterols of P. ginseng have inhibitory effects on inflammation-related factors in HepG2 cells. Methods: Phytosterols (e.g., stigmasterol and ${\beta}$-sitosterol) in the roots of P. ginseng grown under various conditions were analyzed using high-performance liquid chromatography. The P. ginseng roots analyzed in this study were collected from three cultivation areas in Korea (i.e., Geumsan, Yeongju, and Jinan) and differed by cultivation year (i.e., 4 years, 5 years, and 6 years) and production process (i.e., straight ginseng, red ginseng, and white ginseng). Results: The concentrations of stigmasterol and ${\beta}$-sitosterol in P. ginseng roots were 2.22-23.04 mg/g and 7.35-59.09 mg/g, respectively. The highest concentrations of stigmasterol and ${\beta}$-sitosterol were in the roots of 6-year-old P. ginseng cultivated in Jinan (82.14 mg/g and 53.23 mg/g, respectively). Conclusion: Six-year-old white ginseng and white ginseng cultivated in Jinan containing stigmasterol and b-sitosterol are potentially a new source of income in agriculture.

The flowers of Chrysanthemum boreale Makino were extracted with 80% aqueous MeOH, and the concentrated extract was partitioned with n-hexane, EtOAc, n-BuOH and $H_2O$. Two compounds from the n-hexane fraction and one glucoside from the n-BuOH fraction were isolated through the repeated silica gel and ODS column chromatographies. From the result of physico-chemical data including NMR, MS and IR, the chemical structures of the compounds were determined as ${\beta}-sitosterol$ (1), phytol (2) and zingerone $4-O-{\beta}-D-glucopyranoside$ (3). Compounds 2 and 3 were isolated for the first time from this plant.

Evodia daniellii $H_{EMSLEY}$ (Rutaceae) is cultivated in Korea and used as a folkmedicine for gastric inflammation, extermination of noxious insects, headache and antiinflammatory. The seed oil of this plant also has been used in various diseases, for example, dermatitis, scabies and so forth. Fructus Evodiae seed oil sterols were obtained from the nonsaponifiable matters of ethereal extract of the seed. The composition of sterols have been determined by gas liquid chromatography and thin layer chromatography on the preparative plates. It was noted that ${\beta}-sitosterol$ was the major sterols in the Evodia daniellii $H_{EMSLEY}$ in Korea. The results showed that contents of Evodia daniellii $H_{EMSLEY}$ sterols were campesterol 14.01%, stigmasterol 4.36%, ${\beta}-sitosterol$ 71.26%, ${\delta}^7-sterol$ 9.21% and unknown sterol 1.16% by method of triangulation and campesterol 13.02%, stigmasterol 3.87%, ${\beta}-sitosterol$ 74.34%, ${\delta}^7-sterol$ 8.67% and unknown sterol 1.85% by method of planimetry.

We previously identified β-sitosterol (BS) as one of the most abundant compounds found in Korean red ginseng oil. BS is a widely prevalent vegetable-derived phytosterol with many known health benefits. Here, we investigated the efficacy of BS against Brucella (B.) abortus infection. BS showed no effect on bacterial growth but attenuated internalization, intracellular survival and MAPKs-linked intracellular signaling in RAW264.7 cells. BS treatment in cells is also associated with increased nitrite concentration during infection at 24 h. Slightly enhanced resistance to B. abortus infection was observed in mice orally given BS, which could be mediated by induced production of proinflammatory cytokines. Taken together, our study demonstrates the contribution of BS treatment against B. abortus infection although further investigation is encouraged to maximize its beneficial effects against intracellular infection.

Methods for the determination of sterols in sesame oils were studied. The sesame oils were saponified and the sterols isolated from the unsaponifiable matter by Florisil column chromatography, and the individual components were determined by means of gas chromatography. Campesterol, ${\beta}-sitosterol$, stigmasterol were found in sesame oil including unknown Ⅰ and Ⅱ. The use of SE-30 gas chromatographic column allows the slow elution, duplication of peaks and relatively low reproducibility, therefore, 3% OV-17 was suitable for the sterol analysis. The result of this study showed that contents of sterols in sesame oil were campesterol 8.4%, stigmasterol 4.5%, ${\beta}-sitosterol$ 33.9% and others 53.0% involving 8.8% of unknown I and 44.3% of unknown Ⅱ. There has been no specific test available for identifying the sesame oil among common edible oils. But the ratio of sterols in sesame oils allowed the estimation of genuiness. The ratio of sterols vs. campesterol in genuine sesame oils were stigmasterol 0.3- 0.6, ${\beta}-sitosterol$ 3.0-3.8 and unknown Ⅱ 3.0, respectively. The 65 samples were composed of genuine sesame oil 40%, mixed rape seed oil 3%, cotton seed oil 1. 5% others were reused soybean oil or re-extracted oil.
