The aim of this study to determine the relationship stucture between two compounds citronellal and L-tyrosine on antimicrobial activity against Staphylococcus aureus , Escherichia coli , and Candida albicans . The conjugation product obtained was yellow-white solid amorphous with the Rf value was 0.84 and the percentage of yield was 71.12%. The FT-IR spectra peak at 3205.69 cm -1 is represented the N-H stretching vibration from L-tyrosine, while the spectra appears at 1460.11 - 1438.90 cm -1 are represented the C=N which derived from imine or immonium from shift base reaction between citronellal and L-tyrosine. The GC-MS analysis showed that the peak 15 observed at RT 10.27 min. be expected a conjugation product with the m/z 316 [ M +H] + ion. The antimicrobial activity were determined by well diffusion method and the results showed that product of conjugation were have no antimicrobail activities at concentration tested.","PeriodicalId":20554,"journal":{"name":"Proceedings of the 2nd International Conference of Essential Oils","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89084381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the methods that can be used to increase the content of patchouli alcohol is fractional distillation method. This research aims to know the influence of the initial concentration of patchouli alcohol and height of column against increment of patchouli alcohol content in patchouli oil. The experimental design which used was Complete Randomized Design (CRD) consist of two factors, first factor namely the initial concentration of patchouli alcohol (C1 = 31,11%, C2 = 32,83%, and C3 = 33,61%) and second factor is height of column (H1 = 25 cm and H2 = 45 cm). Analysis of variance shows that the height of vigreux column has a real influence against the increased levels of patchouli alcohol. The highest levels of patchouli alcohol (83,86%) obtained from the residue fraction of distillation with 31.11 % initial concentration of patchouli alcohol and 45 cm height of column. The higher levels of patchouli alcohol in patchouli oil residue fraction, the higher specific gravity and the refractive index, and solubility in ethanol will be easier. The result shows that this sample have 1.013 specific gravity, clear in ethanol at 1:5 and have 1.5166 refractive index.","PeriodicalId":20554,"journal":{"name":"Proceedings of the 2nd International Conference of Essential Oils","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90105136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Essential oils have been widely used for stress treatment because they have a calming effect. One of them is cedarwood essential oil. This study was conducted to determine the effect of cedarwood balm against serum cortisol levels in rats which were given stressor. In this study wistar male rats were randomly selected. This animal was exposed to forced swim test as stressor and then they were given cedarwood balm. We used 3 groups, the first group were given a daily forced swim test and applied cedarwood balm on the shaved back, the second group were given a daily forced swim test only, the third group were given nothing. Their serum cortisol levels were measured by ELISA test after 30 days. Result were analysed by Kruskal Wallis test for all group and man whitney test as a post test (p < 0,05). Serum cortisol level was significantly lower in cedarwood balm group then the other groups. When the all group were compared, serum cortisol level was significantly different (p = 0,018). In conclusion this indicates that cedarwood balm affect the endocrine regulatory mechanism to modulate stress responses.","PeriodicalId":20554,"journal":{"name":"Proceedings of the 2nd International Conference of Essential Oils","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86364123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
