Combination of coffee peel from Gayo arabica extract and patchouli from South Aceh as antioxidants : gas chromatography-mass spectrometry (GCMS) studies

Abstract

Indonesia is among of the massive coffee producers country in the world. Aceh is the fourth biggest coffee producer in Indonesia. Coffee processing produces a side-product called coffee peel. Apart from coffee, there are other natural ingredients that have antioxidant benefits, such as patchouli which is a typical Acehnese product. Almost 90% of the world’s patchouli oil supply are from Indonesia, 70% of which comes from Aceh Special Region. The patchouli planted in Tapak Tuan, South Aceh Regency is one of the major varieties. The investigation’s goal is to determine and identify the antioxidant compounds in this combination. Combining coffee peel extract and patchouli extract is necessary because this combination can increase the diversity of antioxidant compounds in the combined extract. The 10% coffee peel extract and 1% patchouli extract that have been combined will be examined using gas chromatography-mass spectrometry. There were 36 compounds from this combination, but only twelve compounds were detected to have antioxidant activity. According to the findings in this study, the combination of 10% coffee peel extract and 1% patchouli extract has antioxidant compounds. The antioxidant compounds can be beneficial in dermatology.
