Demam tifoid adalah penyakit menular yang disebabkan oleh bakteri Salmonella typhi. Penularan ini dapat melalui air ataupun makanan yang tercemar oleh air seni dan feses penderita yang mengandung kuman tifoid. Penelitian ini dilakukan bertujuan untuk mengetahui jumlah pasien dan penyebab demam tifoid yang dilihat dari karakteristik pasien, meliputi jenis kelamin dan umur pasien pada usia (5-11) tahun dan remaja usia (12-25) tahun. Demam tifoid dapat terjadi pada semua usia, Pada Usia anak 5-11 tahun merupakan usia sekolah dimana pada kelompok usia tersebut sering melakukan aktifitas di luar rumah, sehingga beresiko terinfeksi Salomonella typhi seperti jajan disekolah atau diluar rumah yang kurang terjamin kebersihannya (mengkonsumsi makanan dan minuman yang terkontaminasi). Dalam menyusun review ini menggunakan metode studi literatur dalam bentuk referensi primer berupa jurnal nasional dan internasional 10 tahun terakhir. Kemudian, dalam menyusun ulasan ini menggunakan media online yaitu Google Scholar. Dari hasil yang didapatkan pada beberapa jurnal Demam Tifoid disebabkan oleh faktor higienitas dan daya tahan tubuh.

In this journal review, we used different drug compounds from the same biological sample, namely plasma with amoxicillin, glyciburida, vancomycin, amlodipine, and paracetamol. Chromatography-Mass Spectrometry (GC-MS). For the first compounds of amoxicillin, plasma concentrations were measured at 250 g/mL and 500 g/mL, and each concentration was repeated 3 times. Glyciburida, plasma concentration is determined by 3 concentrations namely 1g / mL, 2g / mL and 4g / mL, and each concentration is repeated 5 times. For Vanskomin, 4 concentrations are used for the determination of plasma concentrations, namely 3 g / mL, 15 g / mL, 31.5 g / mL and 48 g concentrations that are suitable for the determination of amoxicillin, which is a level of 500 g / mL. All concentrations are suitable for glyburide determination All concentrations are suitable for glyburide determination The most accurate method is the liquid chromatography/mass spectrometry method (LC/MS), and acetaminophen uses gas chromatography-mass spectrometry (GC/MS) method.-MS), the level of paracetamol in the blood sample obtained is 175.2 ppm.

Hexane is a hydrocarbon compound of alkanes with the chemical formula C6H14. The prefix hex refers to the six carbon atoms found in the hexane and the suffix ana is derived from the word alkane which refers to the single bond connecting the carbon atoms. Identification of terpenoid compounds and steroids has been identified in several plants, namely Red Shoots (Syzygium myrtifolium Walp.), Salam (Syzygium polyanthum), bilaran Tapah (Argyreia nervosa (Burm. F.), Blind (Excoecaria agallocha L.), as well as on the lotion preparations Citrus hystrix DC. This study was conducted to determine the content of terpenoid compounds and steroids found in some parts of plants using n-hexane solvents. Research used is qualitative research with Lieberman Burchard method. Review this article using a method of literature study by searching sources and literature with data form in the form of national journals to international journals about the last 10 years (2012-2021). Identification is carried out on extracts, fractions, isolates and lotion preparations using liquid vacuum chromatography, column chromatography, thin-layer chromatography, and Lieberman-Burchard reagents. The results showed that all of the samples were positive for terpenoid compounds and steroids using n-hexane solvents.
