Chapter I
Sampaguita flowers are blooming almost everywhere in the Philippines. Nevertheless, only a few people are knowledgeable of the full uses of this plant. Around the globe, many researches have already been conducted concerning the volatile oils one could harvest from the plants with rich scents, such as jasmine, rose, and lavander. However, there have been very few researches in the Philippines on the volatile oils of the jasmine, specifically the Jasminum sambac, which is the local plant more commonly known as Sampaguita. This plant is said to be very delicate, requiring meticulous steps in order to obtain the best aroma from it. There are many methods of oil extraction, but not every method is efficient and effective. In relation with this, this study is to be conducted to further widen the scope of the knowledge of the people especially the Filipinos, regarding this plant’s properties and uses. Problem

This study will answer the question:
What is the more efficient and more effective way to obtain the volatile oils of the Sampaguita flower? Hypotheses
Null Hypothesis (Ho): There is no significant difference in the quantity, quality, and odor of the essential oils produced. Alternative Hypothesis (Ha): There is a significant difference in the quantity, quality, and odor of the essential oils.

This study aims to determine the quantity, intensity, and resemblance of the essential oils produced in comparison with the Sampaguita flower using two different methods: solvent extraction and hydro distillation. Specifically, this study aims to achieve the following objectives: 1. To determine which among hydro distillation or solvent extraction is more efficient in producing the desired essential oils 2. To determine the quantity, intensity, and resemblance of the essential oils with the Sampaguita flower 3. To compare and contrast the two essential oils produced using the two different methods 4. To compare the cost of the two methods

Significance of Study
Volatile oils give essential benefits, acting as anti-depressant, expectorant and medicine, to its users. It also has countless uses in the manufacturing sector of the society. For example, it can be used in making perfumes and lotions. Thus, additional information in acquiring such produce efficiently and effectively is significant. More so, the plant to be tested in this study is very abundant in the Philippines, giving a greater possibility of utilizing it. This may result to a lucrative business to whoever desires to engage in a similar study. Scope and Limitations

This study on the production of essential oils using two methods, namely solvent extraction, and hydro distillation only covers collection of significant data which proves the quantity, intensity, and odor resemblance of the essential oils produced in comparison with the Sampaguita flower. It only discusses and highlights significant factors that affect the production of essential oils and its properties. However, this study does not look into the shelf life of the essential oils produced. Furthermore, this study does not include other methods in producing the essential oils. Also, only one product per method is made. No testing on concentrations of the essential oils is performed, and neither is a product made out of the essential oils. Other information on the production of essential oils not mentioned above is not tackled thoroughly in the study. Definition of Terms
