Xantine derivatives are known to have some pharmacological activity, such as a bronchodilator. The substitution on atoms N1 xantine can improve the activity and selectivity as a tracheaspasm. The purpose of this research was to investigate the influence of concentration sodium hydroxide in sodium acetate as solvent used on the production yield of N1-tert-butilteobromin. The result of the synthesis was isolated using chloroform and purified with the preparative thin layer chromatography. The molecule structure of N1-tert-butilteobromin was confirmed using ultraviolet and infrared spectrophotometry. The result showed that sodium hydroxide concentration could effect the results of yield. The yields of 4%, 8%, and 12% sodium hydroxide concentration were 3.7% (0.074 g), 7.2% (0.144 g), and 1.3% (0.026 g), respectively.Keywords: N1-tert-butylteobromin, sodium hydroxide, tert-butylbromide, theobromine

Teh (Camellia sinensis [L.] O. Kuntze) merupakan bahan minuman  kedua yang paling  banyak diminati di dunia setelah air mineral. Pengembangan  metode isolasi  senyawa  metabolit  sekunder teh hitam perlu menjadi perhatian mengingat potensi dan manfaatnya. Salah satu metode yang dapat pilih yaitu dengan menggunakan material mesopori. Pada penelitian ini mesopori dibuat dari campuran CTAB (Cetyl Trimetil Amonium Bromide), etanol absolut, ammonium hidroksida, asam borat, dan TEOS (Tetraethyl Orthosilicate) yang karakterisasi menggunakan instrument Scanning Electron Microscopic, Transmition Electron Microscopic, dan  Fourier Transform Infrared. Selain itu, mesopori silika juga dilakukan penjerapan terhadap ekstrak teh hitam  yang bertujuan mengisolasi senyawa metabolit sekunder teh hitam, salah satunya kuersetin. Pemastian kadar kuersetin dilakukan dengan menggunakan Kromatografi Cair Kinerja Tinggi. Hasil karakterisasi menunjukan bahwa mesopori silika yang dibuat memiliki partikel dengan diameter antara 10-20 nm dan bersifat amorf. Berdasarkan proses penjerapan mesopori terhadap ekstrak hitam menghasilkan fraksi yang memiliki kadar kuersetin sebesar 0,8753 ppm. Mesopori silika dapat dikatakan memiliki kemampuan untuk menjerap beberapa metabolit sekunder  teh hitam, walaupun belum dapat diaplikasikan proses permurnian isolat.

Kunyit (Curcuma domestica L.) termasuk family Zingiberaceae yang banyak terdapat di daerah tropis dan subtropis termasuk Indonesia. Kunyit telah banyak digunakan sebagai pewarna makanan, penambah rasa, dan obat tradisional. Peningkatan kelarutan kurkumin telah terbukti dapat meningkatkan bioavaibilitas dan juga efek farmakologinya. Pembuatan garam kurkumin larut air dilakukan dengan cara reaksi penggaraman dengan menggunakan natrium metoksida sehingga menghasilkan natrium kurkumin yang diharapkan dapat meningkat kelarutannya. Selain itu pada penelitian ini juga dilakukan karakterisasi garam kurkumin dengan spektrofotometri UV-Vis, FTIR, LC-MS, HPLC, dan KLT. Garam natrium Kurkumin dengan perbandingan molnatrium : kurkumin ( 1:1 ) dapat meningkatkan kelarutan kurkumin dalam air sebesar 620 kali. Hasil karakteristik garam kurkumindengan spektrofotometri menunjukann adanya perubahan  panjang gelombang maksimum (λ maks) dari 450 nm menjadi 350 nm. Garam natrium kurkumin menunjukkan adanya substitusi atom H oleh natrium yang mengakibatkan turunnya intensitas puncak pada daerah 3500-3000 cm-1. Hasil ujikarakteristik dengan KLT garam kurkumin dan kurkumin memiliki sedikit perbedaan nilai Rf. Garam natrium kurkumin dapat dibuat dengan mereaksikan natrium metoksida dan kurkumin.

Alpha tocopherol (?-tocopherol) contained in noni fruit (Morinda citrifolia L.) is one of the antioxidants that contribute to pharmacological effects. The noni plant is a tropical plant that has broad growing requirements, so that this plant can grow anywhere. Although easy to find, the environmental conditions where noni grows will have an influence on the amount of ?-tocopherol it contains, one of which is the difference in where it grows. The purpose of this study was to determine the levels of ?-tocopherol in the n-hexane fraction of noni fruit, which grows in three different growing places. Analysis for ?-tocopherol by High Performance Liquid Chromatography (HPLC) with a validated analytical method. The results of system suitability test HPLC System for ?- tocopherol analysis were as follows isocratic elution system of a mobile phase 100% methanol, uv detector at a wavelength of 292 nm using the column C18 (150 ? 4, 6mm, 5?m) flow rate of 1 ml / min. The method had linear concentration range from 1-25 ppm, with R2 0.9967. The accuracy of this method that represented by recovery was 98.02-99.252%. The precision of this method that expressed by Relative Standard Deviation (RSD) was 0.262% and has good specificity. From the analysis, it was found that the content of ?-tocopherol in noni fruit was different and had a positive correlation with the height where it grew, namely in Pameungpeuk (18 m asl) of 0.0316%; Kiaracondong (173 m asl) of 0.0637%; and Lembang (1200 m asl) at 1.0853%.

Purslanes are medicinal plants from the Portulacaceae family which has more than 100 species, including Portulaca oleraceae L. and Portulaca grandiflora Hook. Both types of purslanes have the potential to become natural medicines due to the presence of active chemical compounds that produce various pharmacological effects. This review compiled the data concerning chemical compounds found in those two types of purslanes, the method of analysis, as well as the factors that affect the quality and quantity of chemical compounds so that they can be used as references in determining natural medicinal ingredients by selecting purslanes based on their desired phytochemical compounds and the appropriate analysis. The data were collected by a method of searching research journals on Google Scholar using certain keywords. From this review, the results showed that the chemical compounds found in the two types of purslanes are phenolic, flavonoid, fatty acid, sterol, terpenoid, and alkaloid. These components can be analyzed using spectroscopic and chromatographic methods for both qualitative and quantitative analysis. Some factors that need to be considered in the analysis of these components are the analytical method used, the method of extraction, the solvents, the plant varieties and genotypes, the part of the plant used, the growth time and harvest time of the sample, and the conditions in which the samples grew.
