STEP 2: Characteristics of Volatile Oils (25 minutes) • Volatile oils, also known as essential oils, are concentrated, odoriferous liquids that entirely or almost entirely volatile in steam • Volatile oils are referred to as "essential" in the sense that they carry a distinctive scent, or essence of the plant • Essential oils do not as a group need to have any specific chemical properties in common, beyond conveying characteristic fragrances (Essential oils should not be confused with essential fatty acids) • Volatile oil originates from plants, possess a unique odour or flavour, mainly used in perfumes and flavourings • Essential oils have the following general characteristics o They evaporate under atmospheric pressure at room temperature o They are soluble in alcohol and other organic solvents o They are insoluble in water o They have high refractive index o They are optically active o Most of them are colourless or pale yellow o They are odoriferous o They are sensitive to air (resinify on exposure to air) o Most of them are terpenoid in nature • Resins o Resins are hydrocarbon secretions of many plants, more or less solid amorphous products of complex chemical nature o Resin produced by most plants is a viscous liquid o Resins may be associated with volatile oils or gum or may be found in irregular masses which are insoluble in water but soluble in alcohol o Resins, oleoresins (resins associated with oils) and gum resins (resins associated with gums) are usually secreted into secretory cavities or ducts STEP 3: Composition of Volatile Oils (20 minutes) |Activity: Brainstorming (10 minutes) | | | |DIVIDE students into small manageable groups | | | |ASK students to discuss on the following question | | | |What is composition of volatile oils? | | | |ALLOW students to discuss for 15 minutes | | | |ALLOW few groups to present and the rest to add points not | |mentioned | | | |CLARIFY and SUMMARIZE by using the contents below | • Volatile oils are chemically derived from terpenes (mainly from mono and sesqui terpenes) o Terpenoids are hydroxycarbons of plant origin with general formula (C5H8) n i.e. isoprene units o Terpenoids are naturally occurring and give plants and flowers their fragrance • Many oils are terpenoid in origin, some oils such as cinnamon and clove contain principally aromatic (benzene) derivatives mixed with terpenes • With the exception of oils derived from glycosides (e.g. bitter almond oil and mustard oil), volatile oils are mixtures of hydrocarbons and oxygenated compounds derived from these hydrocarbons • Some oils are acyclic, aromatic or contain sulphur or nitrogen • In some oils (e.g. Oil of turpentine) the hydrocarbons predominate and only limited amount of oxygenated constituents are present, other volatile oils (e.g. Oil of cloves) the bulk of the oil consists of oxygenated compounds STEP 4: Classification of Volatile Oils (15 minutes) • Volatile oils can be classified based on extraction method into; o Concretes ▪ Uses solvent e.g. hexane and waxes or resins to contact the plant materials and then the solvent removed by gent heating e.g. jasmine oil o Pomades ▪ Obtained by enfleurage (hot or cold) e.g. oils from flowers o Resinoids ▪ Extraction with resinous materials i.e. to prolong effect of fragrance o Absolutes ▪ Remains after alcoholic extraction from pomades or concretes • Volatile can be classified on the basis of their functional groups into; o Hydrocarbon volatile oils e.g. turpentine o Alcoholic volatile oils e.g. peppermint, cardamom and coriander oils o Aldehydic volatile oils e.g. lemon oil, orange oil, cinnamon o Ketonic volatile oils e.g. camphor, spearmint oils o Phenolic volatile oils e.g. clove, anise, nutmeg oils o Phenolic ether volatile oils e.g. fennel oil o Oxide volatile oils e.g. rosemary oil STEP 5: Extraction of Volatile Oils (30 minutes) • The following methods are used as general extractions for volatile oils; o Distillation ▪ Water (Simple) distillation (for dry plant materials, materials not destroyed by boiling e.g. turpentine oil) ▪ Water and steam distillation (for dry plant materials not destroyed by direct heating e.g. clove and cinnamon oils) ▪ Steam distillation (for fresh plant materials e.g. peppermint and spearmint oils) • Simple steam distillation • Saturated steam distillation • Hydrodifusion o Scarification ▪ Sponge extraction ▪ Ecuelle method ▪ Enzymatic hydrolysis o Soxhlet extraction o Solvent extraction ▪ Extraction by non-volatile solvents • Enfleurage (hot or cold) • Maceration • Spraying or pneumatic method o Extraction by

NTA Level 5 • Semester 2 • PST05210 Waxes 219 Basic Pharmacognosy • Source Session/Topic 38 Full source-text version: all educational wording from the extracted learning source is retained; only presenter/tutor metadata and web-layout noise are removed, while formatting is improved for readability. Session 38: Waxes 219 Background There is currently an ever-increasing demand for pharmaceutical personnel in Tanzania. This is due to expanding investment in public and private pharmaceutical sector. Shortage of trained pharmaceutical human resource contributes to poor quality of pharmaceutical services and low access to medicines in the country (GIZ, 2012). Through Public-Private-Partnership (PPP) the Pharmacy Council (PC) together with Development Partners (DPs) in Germany and Pharmaceutical Training Institutions (PTIs) worked together to address the shortage of human resource for pharmacy by designing a project named “Supporting Training Institutions for Improved Pharmaceutical Services in Tanzania” in order to improve quality and capacity of PTIs in training, particularly of lower cadre pharmaceutical personnel. The Pharmacy Council formed a Steering committee that conducted a stakeholder’s workshop from18th – 22ndAugust 2014 in Morogoro to initiate the implementation of the project. Key activities in the implementation of this project included carrying out situational analysis, curriculum review and harmonization, development of training manual/facilitators guide, development of assessment plan, training of trainers and supportive supervision. After the curricula were reviewed and harmonized, the process of developing standardised training materials started through Writer’s Workshop approach. The approach included a number of workshops for developing, reviewing, editing and formatting the sessions of the modules. The goals of writer’s workshops were to build capacity of tutors in the development of training materials and to develop high-quality, standardized teaching materials. The training package for pharmacy cadres includes a facilitator guide, assessment plan and practicum. There are 11 modules for NTA level 5 making 11 facilitator guides including one practicum guide. Acknowledgment The development of standardized training materials of a competence-based curriculum for pharmaceutical sciences has been accomplished through involvement of different stakeholders. Special thanks go to the Pharmacy Council for spearheading the harmonization of training materials in the pharmacy after noticing that training institutions in Tanzania were using different curricula and train their students differently. I would also like to extend my gratitude to Christian Social Service Commission (CSSC) for their tireless efforts to mobilize funds from development partners (German Ministry of Industry and action medeor). It is through the implementation of the Multi-Actors Partnership (MAP) project, CSSC has been able to provide the financial and technical support needed during the development of this training material. Many thanks go to the Centre for Educational Development in Health Arusha (CEDHA) experts on health material development and training who coordinated the development of these module sessions particularly Ms. Diana H. Gamuya for her commitment in coordinating and facilitating the planning and development to its completion. Particular acknowledgements are sent to Mr. Dickson Mtalitinya and Members from the secretariat of National Council for Technical Education (NACTE) for facilitating and providing their expertise to the success of this work. It will be unfair if I will not recognize the efforts and contributions of all CEDHA supportive staff that made this process a success; accountant, secretary, drivers and printers Finally, I very much appreciate the contributions of the tutors and content experts representing PTIs, hospitals, and other health training institutions. Their participation in meetings and workshops, and their input in the development of this training manual/facilitators guide have been invaluable. These participants are listed with our gratitude below: Ms. Elizabeth Shekalaghe Registrar, Pharmacy Council of Tanzania Health,MoHCDGEC Dr. Catherine Jincen Acting Principal, CEDHA Dr. Sungwa N.
