“…These components can be terpenes, alcohols, aldehydes, acids, esters, ketones and others. In addition, these components may contain saturated or unsaturated bonds so that patchouli oil is easily oxidized, hydrolyzed and polymerized [3].…”

This study is aimed to examine citric acids as a potential chelating agent to decrease colloidal impurities in patchouli oil to improve its quality. It covers colour, specific density, refractive index, acid value, iron content, oleoresin oil content, and patchouli alcohol. Complete Randomized Design with factorial design is used with two factors and repeated 3 times. Factors are (1) citric acid concentration consists of 0.25%, 0.5%, 1.0% and 1.50% (w/v), (2) stirring time of 30, 60 and 90 minutes. Further, purified oil by citric acid was compared to purified oil by Ethylene Diamine Tetra Acetate (EDTA). Findings show that the concentration of chelating agents and the time of stirring have an effect on the quality of patchouli oil. The higher the chelating concentration and the more the stirring time, the better the quality of purified patchouli oil in terms of colour, specific density, refractive index, acid value, and iron content. Findings also show that citric acid has almost the same performance as EDTA. The main components in patchouli oil (patchouli alcohol and oleoresin oil) are not affected by treatment. Purified patchouli oil by using citric acid meets Indonesian National Standard (SNI) requirements so citric acid is one of the potential chelating agents.

“…Patchouli oil purification can be done by vacuum distillation and re-distillation [3], adsorption [9], and using chelating agents [10]. The redistillation purification method has the disadvantage of being relatively expensive, long processing time and charred-smelling oil [ [11], [12]].…”

Pogostemon cablin Benth is one of the most important crops grown in Indonesia, especially in Aceh province. It is well known as Patchouli belongs to Lamiaceae family and shows a great demand for perfume, luxury products, food and beverage industry. This study conducted to determine the effect of organic fertilizers application on the leaf morphology and stomatal density on the Pogostemon cablin Benth. The seedlings were transplanted for three months on the soil mixed either with manure or compost. The results obtained that was no significant different in affecting the leaf morphology of Pogostemon cablin Benth. The treatment with manure application showed the highest leaf length (15.23 cm) and the highest leaf width (10.5 cm), the leaf color is green. While the stomatal density obtained the significant difference among the treatments, the highest stomatal density in both side of the leaf surface showed in the application of manure, 663.5 mm-2 for adaxial part and 486.38 mm-2 for abaxial part. Stomatal type is anisocytic and on the leaf surface was found glandular and non-glandular trichomes.
