Essential Oil Yielding Plants (Chapter 17), Economic Botany
Mostly they are terpene derivatives, phenylpropanoids, various hydrocarbons and straight chain compounds (seldom longer than 20 carbon atoms) (Figure 17.1). They are distinguished from the fixed oils in their physical and chemical properties. Essential oils have a characteristic aroma or taste that they impart to the plants in which they occur.
A total of 24 oil yielding natively growing plant species belonging to 17 families were documented. These oil yielding plants were used by the different local people and tribals of Nabarangpur.
JOURNAL OF BIODIVERSITY AND CONSERVATION: Oil yielding wild plants
A search conducted to determine the plants yielding vegetable oils resulted in 78 plant species with ... fluid technology for edible use and solvent extracted fixed oils for exclusive
The taxonomic position of these plant species is described with a description of vegetable oils from these plants and their use in cosmetic and skin care products. These species belonged to 74 genera and 45 plant families and yielded 79 vegetable oils. Family Rosaceae had highest number of vegetable oil yielding species (five species).
Edible vegetable oils from oil crops: Preparation, refining
Compared with animal oils, vegetable oils are more popular with consumers due to their renewable utilization, good quality, and lack of cholesterol [3]. The yield of oil crops determines the yield of vegetable oils. In the past 30 years, the production of oil crops has increased by 240% worldwide.
The 225 W microwave power, 15 mL/g solid/liquid ratio, and 20 min extraction time were the optimum conditions necessary to obtain a yield of 87.4% ± 0.44%. The results showed that maximum yields for UAE were obtained in half the time required for microwave assisted extraction (MAE).
A comparative appraisal of three important oil yielding plants for
Annual oil yield per plant in B. aegyptiaca, J. curcas and P. pinnata has been found to be 9.3 kg, 1.5 kg and 16 kg per plant, respectively (Dagar and Minhas 2016). Considering situations like ideal plantation, average seed yield and average oil yield, the final oil yield per hectare has been compared in Table 4 .
Presumably, agriculture began in the Mesolithic or ‘Middle Stone Age’ (12 000 -6000 BC) when man lived by the spear, the bow and the fishing net.This shift from a food gatherer to a food producer is assumed to develop independently at different times in different parts of the world. The Neolithic or ‘New Stone Age’ began about 6000 BC
Larvicidal Efficacy of Crude Seed Extracts of Six Important Oil
The late third and fourth instars larvae were exposed to different concentration (i.e. 25, 50, 100, 250, 500, 1000 ppm) of crude oil extracts of seeds of all the six plants.
Different oil extraction techniques from plant sources are being practiced and work differently: cold pressing extraction (CPE) requires mechanical power and does not need organic solvents ; supercritical-fluid extraction (SFE) uses a supercritical fluid as a solvent; ultrasound-assisted extraction (UAE) involves ultrasonic waves , while microwave-assisted extraction (MAE) uses microwave
