  • The objective of this study was to evaluate the sensory profiles of market milk, yogurt, and kefir, supplemented with the powder of Hibiscus sabdariffa Linnaeus (Roselle) in 1% increments, ranging from 0% (control) to 4%. In this study, there was no statistically significant difference in titratable acidity and pH between the treated groups and the control group. All samples were evaluated in five categories by thirteen appraisers. Compared to the control group, the best sensory profiles were observed in the market milk sample supplemented with 1.0% of Hibiscus sabdariffa Linnaeus (Roselle) powder, in the yogurt samples supplemented with 2.0% and 3.0% of Hibiscus sabdariffa Linnaeus (Roselle) powder, and in the Kefir sample supplemented with 3% of Hibiscus sabdariffa Linnaeus (Roselle) powder. According to statistical analysis of the sensory profiles obtained in this study, there was a statistical difference in the taste, flavor, color, and overall acceptability of market milk; in the taste, color, texture, and overall acceptability of yogurt; and in the taste, color, and overall acceptability of Kefir, between the treated groups and the control group (p<0.05). In the future, when Hibiscus sabdariffa Linnaeus (Roselle) powder is used as a food additive for dairy products, studies on improvement of biofunctionality, as well as of sensory profiles in dairy products must be carried out.

  • Objectives : Hibiscus (Hibiscus sabdariffa L.) is rich in antioxidants such as flavonoids and anthocyanins and is known to have anti-inflammatory activity and anti-aging function of the skin, but there is no study on its effect on the skin barrier. This study aim to investigate the positive effect on the skin barrier by confirming the effect of water extracts of Hibiscus sabdariffa L. (WEHS) on the tight junction-related gene expression. Methods : The antioxidant efficacy of WEHS was investigated through ABTS and DPPH assays, and 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium was performed to examine the effect on cell viability. quantitative Reverse transcription polymerase chain reaction and immunoblot analysis were performed to confirm the effect of WEHS on the expression of tight junction-related genes, and immunofluorescence microscopy was used to confirm the movement of Claudin 1 protein into tight junctions. Results : WEHS showed strong antioxidant activity and induced an increase in both mRNA and protein expression levels of Claudin 1 among tight junction-related genes. The strong localization of Claudine 1 protein increased by WEHS to the tight junction was confirmed by immunofluorescence microscopy. Conclusions : Hibiscus was confirmed through this study to show antioxidant activity and the function of promoting the expression of the tight junction Claudin 1 gene, suggesting that Hibiscus can be used as a material for the prevention and treatment of skin moisturizing and atopy, which have an important influence on tight junction.

  • 본 연구의 목적은 비만 쥐에서의 발효 무궁화 추출물의 항산화 효과를 평가를 위해 수행되었다. 항산화 실험은 in vivo와 in vitro 둘 다 진행하였다. In vitro 실험은 산화질소 자유 라디칼 소거활성을 사용하여 측정하였다. 발효 무궁화 추출물에서의 산화질소 자유 라디칼 소거활성은 비발효 무궁화 추출물보다 높게 나타났다. In vivo 실험은 정상식이군(NOR), 고지방식이군(CON), 고지방식이+발효 무궁화 추출물군(FH)과 고지방식이+비발효 무궁화 추출물군(NFH)로 나눴고, 4군은 4주 동안 복강투여하였다. 그리고 간 균질액의 SOD, CAT, MDA 수준을 측정하였다. 그 결과 FH군의 SOD와 CAT 수준은 CON군보다 높게 나타났으며, FH군의 MDA 수준은 CON군에 비해 현저하게 감소하였다. 결론적으로 발효 무궁화 추출물은 비만 쥐에서의 산화적 스트레스 억제 효과와 항산화 효소 활성 증가 효과를 가지며, 유용한 천연 항산화제의 원료로 사용할 수 있음을 제안한다.

  • 본 연구는 조경수용 무궁화 우수품종 보급을 위한 유전자원 수집과 특성을 평가하기 위해 최근 국내외에서 육성된 127품종의 1년생 접목묘를 이용하여 2014년부터 2015년까지 2년 동안 생육 및 형태적 특성조사를 실시하였다. 수집된 품종 중 화색 및 꽃이 특이한 품종을 조사하여 무궁화를 조경수로 활용도를 높이는데 기여하고자 하였으며 얻어진 결과는 다음과 같다. 최근 국내외에서 육성된 품종들의 화색별 분류로는 크게 분홍색 단심(pink color with red eye spot), 흰색 단심(white color with red eye spot), 붉은 자주색 단심(purplish red color with red eye spot), 분홍보라색 단심(violet pink color with red eye spot), 심홍색 단심(crimson color with red eye spot), 흰색 바탕에 붉은색 무늬의 이중색(asadal), 흰색(white color), 푸른색(blue color) 등 총 8종류로 분류되었다. 화색이 붉은 자주색으로서 적색이 강한 꽃으로 국내에서 육성된 품종으로 '광명', '난파', '노스페이스', '불새', '비단', '송암', '영창', '적퍼소', '키호', '탐라', '화수레드', '환희' 등이 있었으며, 국외에서 육성되어 국내에 도입된 품종으로는 'Aphrodite', 'Dr. Uemoto', 'Freedom', 'Pink Cup', 'PS 80-1', 'Purpureus Variegatus', 'Red Giant', 'Woodbridge' 등이 있었다. 화색이 분홍보라색으로서 특이한 품종으로는 '꼬마', '도투락', '명미', '병화', '산처녀', '태화', 'Hikari-hanagasa', 'Little Kim Violet' 등이 있었다. 화색이 심홍색으로 기존의 꽃에서는 볼 수 없는 특이한 품종으로 '종무'와 'Ruffled Satin' 등이 있었다. 최근 국내외에서 육성된 품종중 조경수용 소재로 보급할 수 있는 품종중 기존 품종에 비해 꽃의 크기가 큰 품종으로 무궁화 종간교잡종인 Hibiscus hybrid 'Daewangchun', 'Daeil', 'Jina' 등이 있었다. 반면 꽃이 작고 조경적 가치가 높은 품종으로 '꼬마', '미백', '안동', '릴킴', '은하수' 등이 있었다. 백단심계 무궁화 '꼬마' 품종은 수고가 작은 왜성형으로 꽃의 크기가 5.2cm로 작은 소형화 품종으로 나타났다. 기존 품종에 비해 단심의 길이가 긴 품종으로 '훈장'과 '하이리레드'가 있었다. 홍단심계 무궁화 '훈장'은 꽃의 크기는 12.0cm로 중간크기이나 단심길이는 4.8cm로 지금까지 육성된 품종중 가장 긴 품종이었다. 또한 홍단심계 무궁화 '하이리레드'의 단심길이 역시 4.2cm로 꽃잎 길이에 비해 단심의 길이가 길어 조경적 가치가 높은 것으로 판단되었다.

  • Column chromatographic separation of the MeOH extract from the aerial parts of Hibiscus manihot led to the isolation of four compounds. Their structures were characterized to be hentriacontane (1), palmitic acid (2), daucosterol (3) and 3-dihydrocaffeonyl-5-p-coumaroylquinic acid (4) by spectroscopic methods. The compounds (1~4) were for the first time reported from this plant. The solvent fractions were tested for their antioxidant activities by free radical scavenging and superoxide dismutase (SOD).

  • The root of Hibiscus syriacus (Malvaceae) has been used for treatment of fungal diseases such as tinea pedis (athlete's foot). In this study, we investigated the antifungal constituent of the root of Hibiscus syriacus Ggoma, which was produced by a mutation breeding using gamma ray irradiation, and compared the antifungal activity of H. syriacus Ggoma and its parent type. According to the results, the methanolic extract of H. syriacus Ggoma exhibited four times higher antifungal activity than its parent type against Trichophyton mentagrophytes. Following purification through various column chromatographies, the antifungal substance was identified as nonanoic acid on the basis of spectroscopic analysis.

  • Anti-inflammatory activity of the extracts of Hibiscus manihot was investigated through the evaluation of its inhibitory effect on the production of inflammatory biomarkers (i-NOS, COX-2) in RAW264.7 murine macrophage cells. Among the sequential solvent fractions (hexane, dichloromethane, ethyl acetate, n-butanol and water), the fractions of dichloromethane (1 ${\mu}g/ml$) and ethyl acetate (5 ${\mu}g/ml$) showed potential inhibitory activities on i-NOS and COX-2 activity in RAW264.7 cells. These results suggest that Hibiscus manihot might have an anti-inflammatory activity through the suppression of inflammatory markers.

  • Hibiscus sabdariffa L., (roselle) in the Malvaceae family is an erect subshrub known to be native to India and Malaysia. It is widely used as a food or tea material around the world, and its therapeutic effects have been widely studied. In this study, the sequencing of the complete chloroplast genome of H. sabdariffa was carried out. The result indicates a genome size of 162,428 bp, which is composed of a large single copy of 90,327 bp, two inverted repeats of 26,242 bp each, and a small single copy of 19,617 bp. Overall, a total of 131 genes were predicted, including 86 coding sequences, 37 tRNAs, and 8 rRNAs. According to a phylogenic analysis, it was clearly distinguished from outgroups such as other species of the genus Hibiscus used in the analysis.
