The Characterization of steam distillation as an Extraction Method to Extract Volatile Compounds from <i>Prunella vulgaris</i>and the Investigation of Their Anti-Tumorous Effect

引用

Journal of Biosciences and Medicines 2021年第8期9卷 120-142页

作者： William Chi Keung Mak Sean Walsh School of Life Science University of Technology Sydney Ultimo New South Wales Australia

Prunella vulgaris (PV) is a perennial plant which is widely grown around the world. It has been widely used as a medicinal treatment for generations. Previous studies showed extracts from this plant had a wide range of therapeutic efficacy, including anti-tumorous effect. However, the volatile organic compounds (VOCs) extracted from it were rarely explored. This paper reports on the characterization of a steam distillation process to extract VOCs in PV and also the anti-tumorous effects of the PV distillate using the tetrazolium-based Cell Counting Kit-8 (CCK-8) as the test agent, when the VOCs were used to treat oral squamous cancer cells, SSC154. It was found that most abundant VOCs came out steadily and continuously for as long as the duration of the steam extraction could extend. However, some compounds such as benzaldehyde did show depletion as the distillation process progressed, while some compounds such as caryophyllene oxide was only sparsely found at the beginning of distillation. The PV distillate was mildly effective in its cytotoxicity to cancer cells SCC154, in a dosage dependent manner.

STUDY ON MASS TRANSFER IN SEPARATION OF ESSENTIAL OILS FROM PLANT MATERIALS BY steam distillation

引用

Transactions of Tianjin University 1995年第2期1卷 165+161-164页

作者：陈涛时媛清张凤宝张国亮

The mass transfer model describing the separation of essential oils from plant materials has been proposed and the mass transfer coefficient has been obtained by fitting the present model to the experimental data for three kinds of plant materials. The validity of the model has been verified. To im' prove the vapor-solid contact, a mechanical agitator has been installed in the steam distillator. The effect of agitating rate on mass transfer coefficient has also been examined.

Wuhan University Journal of Natural Sciences 2007年第3期12卷 529-534页

The physical properties and chemical components of three oil samples extracted from Illicium verum Hook. f. by steam distillation （SD）, solvent extraction （SE） and supercritical fluid extraction （SFE） were compared with one another and analyzed by Gas Chromatography-Mass Spectrometry （GC-MS）. The quality parameters of star anise essential oil from SFE were close to that of those came from SD and SE. Although the extraction yield of star anise by SFE （9.2 %） was close to the value from SE （9.3%）, it was yet higher than that came from SD （8.2%）. For sensory evaluation, however, three oils were significantly different. The odor and taste of the products from SFE and SE were generally more natural and vivid than that came from distilled oil. The volatile compound revealed that significant differences of the composition existed in the distilled oil and the oleoresins prepared by SFE and SE.

Predicting Mass Transfer Extraction with steam Flow, Applying Boundary-Layer Concepts

引用

Journal of Materials Science and Chemical Engineering 2021年第6期9卷 46-58页

作者： Jose Antonio Rocha-Uribe Laura Catalina Soto-Armenta Alfredo Raul Hernandez-Ruiz Jorge Ciro Jimenez-Ocaña Colegio de Bachilleres de Chiapas Tuxtla Gutiérrez Mexico Campus Merida Universidad del Valle de Mexico Mérida Mexico Instituto Tecnológico de Tuxtla Gutiérrez Tuxtla Gutiérrez Mexico

Theory and concepts of boundary layer mass transfer is applied to correlate experimental data on extraction of essential oils from vegetable leaves and stems, using steam. From these theory, concepts and experimental data with seven systems, two correlations are developed to predict the Sherwood number and mass transfer coefficient as function of Reynolds and Schmidt numbers. From these equations, the molar flux, the amount of solute extracted, and the yield of extraction is predicted. A steam of higher temperature normally improves the mass transfer and the yield. A method to estimate the enhancement for temperature increase is proposed. The correlations developed are applied to a case with industrial size that was no part of the data for correlation generation. Theory may be applied for industrial applications.

Medicinal Plant 2018年第4期9卷 13-15,18页

作者： Xu ZHANG Minghui HE Weiyao ZHENG Xu CUI Qingde LONG Key Laboratory of Optimal Utilization for Natural Medicine Resources Guizhou Medical University Department of Pharmacology of Botany and Pharmacognosy Guizhou Medical University

[Objectives] The aim was to determine the optimum process for the extraction of volatile oil from Alpinia zerumbet fruit.[Methods]steam distillation was used to extract volatile oil from A. zerumbet fruit. Based on the single factor tests,an orthogonal test was designed to explore the effects of solid-liquid ratio,soaking time,extraction time and grinding degree of material on the extraction rate. The composition of volatile oil from A. zerumbet fruit was analyzed using gas chromatography-mass spectrometry( GC-MS),and the relative mass fraction of each component was determined by peak area normalization. [Results] With volatile oil yield as the index,the optimum extraction process was determined: solid to liquid ratio of 1∶ 10,soaking time of 0. 5 h,grinding degree of passing through 24-mesh sieve and extraction time of 5 h. A total of 29 compounds were isolated. Among them,the contents of α-terpinene( 24. 894%),1,8-terpadiene( 15. 527%) andα-pinene( 6. 982%) were relatively high. [Conclusions]The optimized extraction process for volatile oil from A. zerumbet fruit is stable and reasonable. Under the optimum extraction process,the extraction effect of volatile oil from A. zerumbet fruit was the best. The chemical components of volatile oil from A. zerumbet fruit were determined by GC-MS as α-terpinene( 24. 894%),1,8-terpadiene( 15. 527%) and α-pinene( 6. 982%).
