Combination Techniques for Fast and Low-Waste Identification and Separation of Fragrances from Persicaria odorata

Abstract
Fragrance of Persicaria odorata has been using for decades in ASEAN states, from food to perfume industries. Identification and separating of its effective volatile substances for its true scent require high resources and time. Therefore, this study used combination techniques of extraction, distillation and chromatography to develop faster and lower-waste method. It was found that the most abundance fragrances were aldehydes. Real fragrances content in essential oil was 54.61% while extracts varied from more than twenty to over eighty percentages with lesser chemical diversity. This procedure may be applied to experimental planning and increasing in fragrance separation efficiency. Keywords - Fragrance, Persicaria odorata, Separation, Solid-phase microextraction
