Total antioxidant capacity of piper betel hydrosol

Abstract

Piper Betel has been used as a medicinal herb in Thailand for a long period. Not only consumption but Piper Betal also has been used for religious belief and ritual. However, the piper leave should be in the good condition without any defect. As a result, there are numerous fall-grade leaves to be get rid of from agriculture. Increasing the value-added of this by- product can increase the income. Extraction of bioactive compounds by using alembic is uncomplicated and green without any solvent is required. Two products come out from this process, the first one is an essential oil, which is expensive. The second product is hydrosol. The piper hydrosol still contained various phytochemicals. In this study, total phenolic content was investigated and was found to be in the range 31.16-73.71 GAE mg/g. Total antioxidant capacity was also studied using the DPPH method. The antioxidant activity was 0. 37▁(+)0.11 mg ascorbic acid equivalent/ ml hydrosol. However, the piper hydrosol cannot inhibit P.ance, S.aureus, and S.epideminis. To sum up, the piper hydrosol can be used as an ingredient for antioxidant cosmetics rather than antibacterial skincare.
