In order to analyze trigonelline, caffeine, chlorogenic acid, and their related compounds simultaneously, an HPLC method using InertSustain C18 column a mobile phase containing octanesulfonate as ion-pairing reagent under acidic condition was developed. The optimum conditions were determined be 0.1% phosphoric 4 mM octanesulfonate, 15% methanol at 35°C. Using the proposed method, nicotinic theophylline, caffeic acid in ten instant coffee samples analyzed. These analytes except for...

Abstract Age is necessary information for the study of life history wild animals. A general method to estimate age odontocetes counting dental growth layer groups (GLGs). However, this highly invasive as it requires capture and handling individuals collect their teeth. Recently, development DNA‐based estimation methods has been actively studied an alternative such methods, which many have relied on used biopsy samples. if can be developed from faecal samples, performed entirely...

Age is an important parameter for bettering the understanding of biodemographic trends—development, survival, reproduction and environmental effects—critical conservation. However, current age estimation methods are challenging to apply many species, no standardised technique has been adopted yet. This study examined potential use methylation-sensitive high-resolution melting (MS-HRM), a labour-, time-, cost-effective method estimate chronological from DNA methylation in Asian elephants (...

Abstract Age is an important parameter that provides a better understanding towards biodemographic trends–development, survival, reproduction and environmental effects–which critical for conservation. However, current methods to estimate age difficult in many species no standardised technique has been adopted. Here, we focus on the endangered Asian elephants ( Elephas maximus ) examine potential of estimating from DNA methylation through two candidate age-related epigenetic genes develop...
