| Summary: | Ocimum gratissimum (O. gratissimum) is a medicinal plant which native in Southeast Asia. Containing various compound
with medicinal value, it acts as herb and spices in cooking, perfumery and used in traditional preparation. It is reported that
O. gratissimum has many phenolic compounds which responsible for many biological activities such as eugenol, limonene,
ocimene and rosmarinic acid. Scientific studies regarding O. gratissimum are widely known due to its beneficial therapeutic
properties, such as antioxidant, antibacterial, anti-inflammatory and others. However, different extraction techniques
approaches will give different effects on extraction yield of bioactive compounds according to the processing condition
such as solvent polarity, concentration of solvent, temperature and solvent to sample ratio that applied. This study applied
Soxhlet and Ultrasonic-assisted Extraction (UAE) techniques to determine the extraction yield of O. gratissimum. The results
indicated Soxhlet techniques requires 2 hours, sample to solvent ratio; 1:10 and temperature at 60oC to obtained highest
yield of O. gratissimum extract with percentage yield at 1.723% compared to others processing conditions. Meanwhile, UAE
techniques showed highest yield of O. gratissimum extract at sample to solvent ratio at 1:10 with results 20.60% and 60%
Methanol as the best solvent for extraction. Throughout analysis, UAE techniques was chosen as the methods of extraction
for O. gratissimum with processing conditions that gives high yield of extraction. |
