“…Minyak kenanga tersusun atas beberapa komponen utama yaitu β-caryo-phyllene (36,44%), senyawa dominan lainnya benzyl acetate, (E,E)-Farnesene, δ-cadinene, p-linalool, methylanisole, methyl benzo-ate, geranyl acetat, benzyl benzoate (Tan et al, 2015). Terdapat senyawa β-caryo-phyllene dalam minyak kenanga menyebabkan minyak kenanga bersifat nonpolar (Andila et al, 2020). Sifat minyak kenanga yang non-polar menjadikan minyak kenanga berpotensi menggantikan peran xylol dalam proses deparafinisasi pewarnaan HE.…”

Histological staining usually requires deparaffinization before starting the staining process. Deparaffinization is a paraffin removal step that often uses a xylol solution. Deparaffinization with xylol has disadvantages, including being toxic, harmful to the human body, and hazardous to the environment. A safer alternative to xylol is required. Ylang-ylang oil, which contains β-caryophyllene, is non-polar and can be used as a substitute for xylol. This study aimed to compare the staining quality of guinea pig liver tissue slides with and without heating as a deparaffinization agent in hematoxylin-eosin (HE) staining. The research set up a quasi-experimental approach using samples of guinea pig liver tissue slides. The sample size was calculated using the Federer formula (n-1) (t-1) ≥ 15, resulting in a total sample of 27 slides divided into three treatment groups: xylol, ylang-ylang oil with and without heating. The Kruskal-Wallis test was used to examine the data. The quality staining of guinea pig liver slides deparaffinized with xylol was 100% good, and deparaffinization of ylang-ylang oil with heating was 100% good, whereas deparaffinization with ylang-ylang oil without heating was 11.1% less good, and the quality was good with an 88.9%. The normality test indicated that the data were not normally distributed (p0.05). The Kruskal-Wallis test was then used.

“…Essential oils are in great demand by consumers around the world due to the shift in interest from products based on synthetic compounds to natural products derived from plants, including products of chemical base compounds contained in essential oils [2]. Indonesia produces 40 of the 80 globally traded essential oil varieties, experiencing an annual demand increase of 8-10% [3]. Among these, gandapura essential oil, also known as wintergreen oil, stands out.…”

Gandapura oil, also called wintergreen oil in international trade, is evaluated based on the purity of its methyl salicylate content. Gandapura oil has several impurities including mainly ethyl salicylate and α-pinene, which can lower its quality and price. Indonesian local farmer’s gandapura oil has a low methyl salicylate content of only 82.23%, and appears in a dark red colour instead of clear. The low grade product may have been caused by thermal degradation of compounds within gandapura oil by constant heating during atmospheric distillation at temperature above its thermal threshold. The determination of their vapor-liquid equilibrium data can provide basic data for the separation and purification of methyl salicylate towards its two main impurities in gandapura oil. The vacuum pressure condition was selected to lower the distillation temperature, aiming to reduce the chance of thermal decomposition. The vapor-liquid equilibrium under isobaric conditions in the binary systems of methyl salicylate + ethyl salicylate and methyl salicylate + α-Pinene at 20.0 and 50.0 kPa were measured experimentally using modified Glass Othmer-Still. Gas Chromatography (GC) was utilized to analyze the composition of both the liquid and vapor phases in the samples. The thermodynamic consistency of experimental data was confirmed through the L-W Wisniak method. The experimental results were successfully correlated with Wilson, NRTL, and UNIQUAC models. The average absolute deviations of temperature (AAD T) and vapor phase composition (AAD y) between experimental data and models are less than 0.8058 and 0.0196, respectively for all systems. In terms of quality, all samples collected post-experiment maintained a clear color, suggesting that vacuum pressure distillation effectively prevents the thermal decomposition of compounds in gandapura oil.

“…As one of the largest producers of essential oils in the world, Indonesia produces 40 kinds of essential oils, one of them being Citronella oil. 1 In terms of the need for citronella essential oil on a world market scale, the need for citronella essential oil increases by 3−5% per year. 2 Although Indonesia is an exporting country for citronella essential oil, the products sold are still in the crude form because the quality of Indonesian citronella oil still does not meet the export quality requirements.…”

Isobaric Vapor–Liquid Equilibrium of Citronellal + Geraniol and Citronellal + Citronellol Binary Systems at 16.0 and 32.0 kPa

The isobaric vapor–liquid equilibrium data for citronellal + geraniol and citronellal + citronellol systems were obtained experimentally at vacuum pressures of 16.0 and 32.0 kPa using a modified glass Othmer still. Gas chromatography was used to analyze the equilibrium samples of liquid- and vapor-phase compositions. The reliability of the experimental data determined in this study was confirmed using the L–W Wisniak and Fredenslund methods. The data were correlated with the Wilson, NRTL, and UNIQUAC equations to obtain the binary parameters, resulting in an average absolute deviation of the temperature of less than 0.5 and a vapor fraction of less than 0.0286. Prediction of the vapor–liquid equilibrium data of related systems was obtained using UNIFAC, giving better results at 16.0 kPa.
