Judul: Metode cepat untuk kuantifikasi teoflin dalam sediaan farmasi secara spektrofotometri derivatif ultraviolet
Abstrak: Teofilin merupakan senyawa alkaloid yang telah lama digunakan untuk mengobati penyakit asma. Metode cepat dan dapat dipercaya untuk penentuan teofilin diperlukan untuk mendukung kontrol kualitas obat. Metode spektrofotometri derivatif ultraviolet (SDUV) tanpa teknik pemisahan telah dikembangkan untuk penentuan teofilin di dalam sediaan farmasi. Metode SDUV ditentukan berdasarkan pengukuran jarak puncak ke puncak pada spektrum turunan orde pertama. Kurva kalibrasi yang dibuat pada selang konsentrasi 5.0-30.0 ppm menghasilkan koefisien korelasi yang tinggi sebesar 0.9994 berdasarkan metode kuadrat terkecil. Ketelitian metode SDUV yang dianalisis pada hari yang sama sangat memuaskan dengan nilai persen simpangan baku relatif untuk contoh A dan B secara berturut-turut sebesar 1.89% dan 1.15%. Nilai perolehan kembali berdasarkan metode penambahan standar sebesar 69.23-86.47%. Limit deteksi dan limit kuantisasi secara berturut-turut sebesar 1.08 μg/mL dan 3.63 μg/mL. Metode kromatografi kinerja tinggi digunakan sebagai metode terstandar untuk penentuan teofilin. Hasil analisis kedua metode dibandingkan secara statistika menggunakan uji F dan uji t. Analisis secara statistika menunjukkan bahwa nilai ragam dan rataan kedua metode berbeda nyata untuk contoh A dan tidak berbeda nyata untuk contoh B pada selang kepercayaan 95%.
