 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Comparative Study of Scented Compound Extraction from Plumeria obtusa L.) ผู้เขียน: Potechaman Pitpiangchan,  นางอุไรวรรณ ดิลกคุณานันท์ , Udomlak Sukkatta, ดร.สรัญญา วัชโรทัย, รองศาสตราจารย์ , Vichai Haruethaitanasan, Putthita Punjee, Prapasson Rukthaworn สื่อสิ่งพิมพ์:pdf AbstractVarious scented compound extraction methods were studied using Plumeria obtusa L. flowers: water distillation, steam distillation, water-steam distillation, hexane extraction, petroleum ether extraction, and cold and hot enfleurage. Chemical compounds of the extracts from each method were analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed the percentage yield of the extracts was 0.0167, 0.0045, 0.0342, 0.4170, 0.3510, 0.3969 and 12.2400%, respectively. The major chemical component in the essential oils from all distillation methods and both solvents was benzyl salicylate, but the extracts from cold and hot enfleurage were linalool and n-undecanoic acid, respectively. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Scented Extracts and Essential Oil Extraction from Michelia alba D.C.) ผู้เขียน:Putthita Punjee, นางอุไรวรรณ ดิลกคุณานันท์, Udomlak Sukkatta, ดร.สรัญญา วัชโรทัย, รองศาสตราจารย์, Vichai Haruethaitanasan, Potechaman Pitpiangchan, Prapassorn Rakthaworn สื่อสิ่งพิมพ์:pdf AbstractThe study assessed extractions of scents and essential oils from Michelia alba D.C., with water, steam, water-steam distillation, cold enfleurage using palm stearin and hot enfleurage using palm oil, hexane and petroleum ether extraction. The yields of M. alba essential oils from the three distillations were 0.225, 0.120 and 0.199%, respectively. The percentage yields of M. alba absolutes obtained from cold and hot enfleurage, hexane and petroleum ether extractions at saturation point (1,500 g of flower/ 200 ml of fat, 400 g/ 400 ml of oil, 200 and 150 g/L of solvent) were 0.3511, 2.7506, 0.0457 and 0.0497%, respectively. The chemical composition of the essential oils and absolutes was analyzed by GC-MS. The results showed that linalool was the major component of the oils and indole, linalool and phenylethyl alcohol were the major components of the absolutes. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Extraction Methods for Tuberose Oil and Their Chemical Components) ผู้เขียน:Prapassorn Rakthaworn, นางอุไรวรรณ ดิลกคุณานันท์, Udomlak Sukkatta, ดร.สรัญญา วัชโรทัย, รองศาสตราจารย์, Vichai Haruethaitanasan, Potechaman Pitpiangchan, Putthita Punjee สื่อสิ่งพิมพ์:pdf AbstractThe objectives of the project were to compare essential oil extraction methods from the doubleflower variety of tuberose (Polianthes tuberosa L.). The flowers were extracted by cold or hot enfleurage, or by solvent extraction with hexane or petroleum ether. The chemical composition of the tuberose absolutes was analyzed by gas chromatography-mass spectrometry (GC-MS). The results showed that percentage yields of tuberose oil from cold enfleurage, hot enfleurage, hexane and petroleum ether extractions were 0.3137%, 6.5808%, 0.0279% and 0.0182%, respectively. The main chemical component detected in both enfleurage absolutes was methyl benzoate, while benzyl benzoate and pentacosane were found to be the main chemical components in hexane and petroleum ether absolutes, respectively. |

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Development of Mangosteen Anti-Acne Gel) ผู้เขียน:ดร.อุดมลักษณ์ สุขอัตตะ, นางสาวประภัสสร รักถาวร, Potechaman Pitpiangchan, นางอุไรวรรณ ดิลกคุณานันท์ สื่อสิ่งพิมพ์:pdf AbstractThe ethanolic fruit peel extracts from mangosteen (Garcinia mangostana L.) which is widely grown in the east and the south of Thailand have potential for inhibiting acne - causing bacteria. The purpose of the present study was to develop mangosteen anti-acne gel by using 32 factorial design. The result showed that the optimal formula of anti-acne gel with mangosteen crude extract contained water, Carbopol Ultrez-10, Triethanolamine, Panthenol, Dimethicone, Germaben II, Polysorbate 20 and mangosteen crude extract 94.2%, 0.5%, 0.5%, 0.5%, 2.0%, 0.8%, 1.0 % and 0.5%, respectively. Antiacne gel with mangosteen crude extract was yellowish brown in color with L*, a* and b* 31.39, 2.19 and 4.49, respectively. The gel pH was 6.07 and its viscosity was 8023.33 cP. The mangosteen anti-acne gel was satisfactorily effective to control acne inducing bacteria; Staphylococcus aureus, S. epidermidis and Propionibacterium acnes. In addition, the consumer acceptance test with 120 targeted consumers showed that 71.7 % of them accepted the gel and the overall liking was a little like. |
