생황장에 양파를 첨가하였을 때와 무장과 비지장에 표고버섯을 첨가하였을 때, 그리고 찌금장에 다시마를 첨가하였을 때 휘발성 성분을 추출하여 분석 동정하였다. 생황장은 furfural, benzeneacetaldehyde, n-hexadecanoic acid 등이 많이 검출되었고 양파 첨가구에서 1-hexanol, 2,5-dimethylthiophene은 숙성 4일 후에 각각 0.07, 0.11 ppm이 검출되었다. 생황장은 발효 4일된 시료에서 향기성분의 함량이 비교적 높게 나타났으며, n-hexadecanoic acid의 경우 발효 4일된 시료는 발효초기 함량보다 10배 이상 높게 나타났다. 무장에서의 1H-indole과 phenol은 발효초기에는 대조구에서 각각 130.02, 85.38 ppm이었고, 6일째에는 각각 129.68, 95.99 ppm이었다. 표고버섯 첨가 시 1H-indole은 각각 121.90 ppm에서 114.44 ppm으로, phenol은 각각 87.48 ppm에서 75.64 ppm으로 감소하였다. 3-Allyl-6-methoxyphenol, ${\gamma}-dodecalactone$ 등은 대조구에서 검출이 되었으며, 1,2,4-trithiolane, 2-buthyl-2-octenal은 표고버섯 첨가구에서 검출되었다. 비지장에서는 2,4-decadienal이 대조구는 발효초기에는 2.76 ppm, 발효 1일에는 6.46 ppm, 2일에는 5.02 ppm이 검출되었고 표고버섯 첨가구는 발효초기에는 2.92 ppm, 발효 1일에는 3.84 ppm, 2일에는 3.60 ppm이 검출되어 표고버섯 첨가시 함량이 감소하는 것으로 나타났다. Furfural은 증가하는 경향을 보였고, 1,2,4-trithiolane과 lenthionine은 표고버섯 첨가한 시료에서만 검출되었다. 찌금장은 tetramethylpyrazine, hexadecanal, tetradecanoic acid methyl ester, n-hexadecanoic acid, linoleic acid dthyl ester 등이 검출되었고 발효가 진행되어도 이들 성분의 변화는 적었지만, linoleic acid ethyl ester는 감소하였다. 전체적으로 부재료를 첨가하였을 경우에 장 특유의 이취로 알려진 pyrazine류나 hexadecanoic acid 등의 지방산의 함량이 감소하는 것으로 나타났다.

층꽃나무 지상부위 정유의 화학성분 구명을 위하여 수증기증류법으로 정유를 얻고, 이를 solid-phase microextraction(SPME)와 headspace(HS)법으로 흡착시킨 다음 CC-MS로 분석하였다. 향취가 fougere, woody한 층꽃나무 정유에는 탄화수소 28종, 알코올 22종, 아세테이트 7종, 케톤 7종, 알데히드 3종, 기타 2종 등 총 69종의 화학성분이 함유되어 있었으며, 다함량 성분은 4,6,6-trimethyl [1S-($1{\alpha},2{\beta},5{\alpha}$)]-bicyclo[3.1.1]hept-3-en-2-ol(11.8%), tau-cadinol(9.4%), myrtenyl acetate(9.2%), pinocarvone(7.0%), 1-hydroxy-1,7-dimethy 1-4-isopropyl-2,7-cyclodecadiene(6.3%), ${\delta}$-3-carene(6.2%)이었다. SPME법으로 흡착 후 분석한 시료에는 탄화수소 22종, 알코올 16종, 아세테이트 6종, 케톤 3종, 에테르 2종 등 총 49종의 화학성분이 검출되었는데, 다량 함유된 성분으로는 ${\delta}$-3-carene(12.6%), (-)-myrtenyl acetate(11.2%), 6,6-dimethyl-2-methylene-bicycol[3.1.1] heptan-3-ol(10.9%), pinocarvone(9.3%)이었다. 그리고 HS법으로 흡착한 다음 분석한 정유에는 탄화수소 5종, 아민 2종, 알코올 1종, 기타 2종 등 총 10종의 화학성분이 검출되었는데, 다량 함유된 성분은 (Z)-2-fluoro-2-butene(34.9%), ${\delta}$-3-carene(6.9%), 6-(4-chlorophenul) tetrahydro-2-methyl-2H-1,2-oxazine(5.9%)이었다. HaCaT 각질형성세포에 미치는 세포독성을 조사하기 위하여 MTT assar를 실시한 결과 층꽃나무 정유의 $IC_{50}$값은 0.011 ${\mu}g/mg$으로 시판 중인 로즈마리 정유나 차나무 정유의 $IC_{50}$값보다 낮았는데, 이러한 결과는 층꽃나무 정유의 상업화를 위해서 더 많은 독성시험이 요구된다는 것을 시사한다.

Objective: To elucidate 1) whether there are any differences in the urine concentrations of steroid hormone metabolites between patients with leiomyoma and normal controls 2) the correlation between urinary profiles of steroid hormones and leiomyomas of the uterus according to their type, location, volume, and weight. Materials of Methods : The study population consisted of 37 premenopausal patients with uterine leiomyoma and the control group consisted of 25 premenopausal normal volunteer women without uterine leiomyoma. Confirmation of the existence of uterine leiomyoma was done by ultrasonography and histopathological examination after surgery. The volume of the leiomyoma was estimated by trans-abdominal and/or trans-vaginal ultrasonography. The Leiomyomas were divided into 3 types (subserosal, intramural and submucosal). Seventeen patients had subserosal type of leiomyoma, 10 with the intramural type and 10 with the submucosal type. The locations of the leiomyoma were also divided into 3 groups (fundus, body and isthmus). Seventeen patients showed a fundus location, 10 in body, and 10 in isthmus. We compared urinary profiles of the endogenous steroids between patients with leiomyomas and normal controls, and also investigated the relationship between urinary profiles of the endogenous steroids and leiomyomas according to their type, location, volume and weight by using highly sensitive Gas Chromatography-Mass Spectrometry (GC-MS) system. Results: The mean ages of the patients with leiomyomas and the control group were $43.1{\pm}5.6$ and $40.6{\pm}7.2$ years, the weights were $63.4{\pm}7.3$ and $59.4{\pm}8.1\;kg$, and their heights were $155.4{\pm}4.8$ and $159.3{\pm}4.8\;cm$ respectively. Seventeen patients had subserosal, 10 had intramural, and 10 had submucosal leiomyomas. There were 17 patients with leiomyoma located in fundus, 10 in body and 10 in isthmus. $17{\beta}$-estradiol, 5-AT, 11-keto ET, $11{\beta}$-hydroxy An, $11{\beta}$-hydroxy Et, THS, THA, THE, a-cortolone, a-cortol, $\beta$-cortol, $11{\beta}$-OH Et/$11{\beta}$-OH An and E2/E1 were significantly increased in patients with leiomyoma than in the control group. $17{\beta}$-estradiol was significantly increased in the intramural and the submucosal types than in the subserosal type. There was no significant difference in the concentrations of urinary steroids according to the locations of leiomyomas. There was no significant relationship between the concentration of urinary steroids and the volume of the leiomyomas. $17{\beta}$-estradiol significantly decreased as the weight of uterus increased (r=-0.322, p=0.04). Conclusion: The concentrations of steroid hormone metabolites were generally increased in patients with leiomyoma but were not significantly related to the volume and weight of the leiomyomas. Our study suggests that steroid hormones may be involved in the initiation of leiomyomas but may not be involved in their progression. In addition, the concentrations of steroid hormone metabolites are not related to the leiomyoma type and location.
