Abstract:
This objective of this research was to extract and evaluate phenolic content and bioactivities of Ma-Kwaen (Zanthoxylum limonella Alston) for application as massage lotion. The separated husk and seed of Ma-Kwaen fruits were extracted by 2 different extraction methods including hydrodistillation and soxhlet extraction using 95%ethanol and DI water. The results showed that the highest yield was obtained from the husk extracted by soxhlet-assisted extraction method using ethanol for 6 hours (47.4±0.02% w/w). Antimicrobial activity of the all extracts was found that they showed different activities against three microorganisms tested that are Pseudomonas aeruginosa, Staphylococcus aureus and Candida albicans. The queous extract can inhibit the all microorganisms. The ethanolic extract only had an inhibition effect on Candida albicans, whereas the hexane extract provided the activity against among Staphylococcus aureus and Candida albicans. Investigation of phenolic content and DPPH radical scavenging activity of Ma-Kwaen revealed that the husk extracted by ethanol for 3 hours showed the highest phenolic content and IC50 value of 149.05±3.60 mg GAE/g extract and 0.060±0.001 mg/ml, respectively. Development of massage lotion containing 0.2% the ethanol extract of Ma-Kwaen husk was demonstrated and found that the product had good stability in terms of viscosity, pH and color
after passing the accelerated conditions tested (45 and 5 C, as well as ambient temperature). In addition, preference test from 30 volunteers showed that the product was ranged in good level. Further excellent satisfaction was also obtained if essential oils were added to the product in terms of smell, feel on use and overall satisfaction.
