Sampel feses dikoleksi dari dua kelompok M. Nigra yang hidup di Cagar Alam Tangkoko-Batuangus (1°30′ to 1°34′ N; Kata kunci: Macaca nigra, preservasi, ekstraksi, metabolit progesteron, metabolit estrogen. ABSTRACT This study was conducted to develop a technique of preservation, extraction, and biological validation of metabolites progestrone and estrogen in feces for hormone analysis through enzyme immunoassay. Fecal samples were collected from Two groups of crested macaques (Rambo I and Pantai Batu) living in Tangkoko-Batuangus Nature Reserve (1°30′ to 1°34′ N; 125°3′ -125°15′ E) in North Sulawesi. Three diffrent techniques of preservation and extraction (freeze drying, oven drying and field extraction) were performed to evaluate the best technique of fecal samples preservation and extraction for hormone analysis. Moreover, Three different hormone assay of progesterone (PdG,progesterone DH, pregnanolone Mostl) and estrogen (E1C, E2, Etotal) were tested to evaluate the best and reliable assay for measuring metabolites progesterone and estrogen in M. Nigra. Our result shown that although freeze drying was the best technique compared with the oven drying and field extraction. However, field extraction was not significant with freeze drying. Pregnanolone Mostl was the most reliable hormone assay for measuring progesterone metabolite, whereas Estrone (E1C) was the most reliable hormone assay for measuring estrogen metabolites. Keywords: Macaca nigra, preservation, extraction, metabolite progesterone, metabolite estrogen. |
