Abstract
Essential oil of nutmeg (Myristica fragrans houtt) is one of the many potentials of nutmeg that has a high economic value although in North Sulawesi it has not been exploited to its full potential. This research was conducted to compare the yield and properties of Nutmeg oil extract from the seeds and mace of Talaud and North Minahasa-North Sulawesi. The oil extract was obtained by distillation and was further characterized in terms of color, solubility in ethanol, density, optical rotation, refractive index. Results of this research exhibited that oil of the mace of nutmeg from Talaud had a lighter appearance in color compared to that from North Minahasa, while the density of oil extracted from North Minahasa was more densed compared to Talaud in both seed and mace (0.923 and 0.938 respectively at 25°C). The reflective index of nutmeg oil from North Minahasa was slightly higher than of Talaud both from seed and mace (1.4834 and 1.493 at 25°C), while the optical rotations of oil extracted from the mace were between +6.90° to +9.80° and from the seed were +20.73° to +22.30°.
Highlights
Rismunandar, described the Myristica fragrance houtt, the Indonesian Nutmeg originated from the island of Banda [1]
The color of nutmeg maces of Talaud were yellowish to brownish in color, the North Minahasa maces were more brownish in color, while nutmeg oil obtained from the seeds from Talaud or North Minahasa are more yellowish (Fig 1.)
The North Sulawesi nutmegs in the findings of this research remained consistent with previous researches, while remained within standard with the standards set by the National Indonesian Standards
Summary
Rismunandar, described the Myristica fragrance houtt, the Indonesian Nutmeg originated from the island of Banda [1]. The nutmeg essential oil physicochemical analysis begins from the oil yield, visual appearances, and solubility in alcohol, density, optical rotation and refraction indexes; where all were done to the SNI (Standard Nasional Indonesia).
