Senyawa bahan alam yang terdapat pada tanaman memiliki banyak khasiat bagi kesehatan yang telah dibuktikan melalui pengobatan tradisional secara empiris. Identifikasi senyawa kimia sangat penting untuk mengetahui kemungkinan adanya senyawa yang dapat memiliki aktivitas farmakologi. Tanaman yang telah banyak digunakan oleh masyarakat termasuk pengobatan adalah temu kunci (Boesenbergia rotunda L.) dan serai (Cymbopogon citratus). Temu kunci dan serai diekstraksi menggunakan pelarut etil asetat. Uji fitokimia pada ekstrak etil asetat temu kunci dan serai dilakukan dengan uji kualitatif pereaksi warna dan pengendapan serta kromatografi lapis tipis untuk melihat gambaran pemisahan senyawa kimia yang terkandung. Ekstrak etil asetat temu kunci dan serai mengandung senyawa golongan alkaloid, terpenoid, flavonoid, fenol, dan kuinon. Senyawa pada temu kunci dan serai dapat dipisahkan menggunakan kromatografi lapis tipis dengan fase gerak etil asetat : n-heksan (8:2).    Kata Kunci: Fitokimia, Temu Kunci, Serai, Ekstrak Etil Asetat, Kromatografi Lapis Tipis Natural compounds found in plants have many health benefits that have been proven through empirically traditional medicine. Identification of chemical compounds is very important to determine the possibility of compounds having pharmacological activity. Plants that have been widely used by the community, including medicinal plants, are Temu Kunci (Boesenbergia rotunda L.) and serai or lemongrass (Cymbopogon citratus). Temu Kunci and lemongrass were extracted using ethyl acetate as a solvent. Phytochemical test on ethyl acetate extract of temu Kunci and lemongrass was carried out by qualitative test using color reagent and deposition and thin layer chromatography to see the description of the separation of the chemical compounds contained. Temu Kunci and lemongrass ethyl acetate extracts contain alkaloids, terpenoids, flavonoids, phenols, and quinones. Compounds in Temu Kunci and lemongrass can be separated using thin layer chromatography with ethyl acetate: n-hexane (8: 2) as mobile phase.

Karamunting or Kalimantan Grapes (Rhodomyrtus tomentosa) is a medicinal plant from Central Kalimantan that is easily found in shrubs. Based on hereditary experiences of the people of Central Kalimantan, karamunting can be used for the treatment of various diseases, one of which is diabetes. This study aims to identify the chemical compounds contained in the karamunting stem. The method used is thin layer chromatography with eluent n-hexane : ethyl acetate and methanol : chloroform. Besides, a color reaction was carried out to determine the group of compounds contained in the methanol extract of the karamunting stem. The TLC results show better stain separation in eluent n-hexane : ethyl acetate with the formation of four stains. Positive results are indicated by the content of phenol, saponin, flavonoid and terpenoid compounds. The existence of this group of compounds can be a clue to further research on the truth of the efficacy of karamunting.

Abstract A rapid, simple, convenient, and widely applicable method for the direct fluorescent detection of organothiophosphorus pesticides and some postulated breakdown products of these compounds is presented. The coinpounds were spotted on thin layer chromatographic sheets, developed in ethyl acetate :nhexane, and made visible by exposure to bromine vapor followed by spraying with ferric chloride and 2-(o-hydroxy phenyl) benzoxazole. Of the 47 compounds tested, 32 compounds produced fluorescent blue spots vinder longwave ultraviolet light; these consisted of 25 organothiophosphorus pesticides, 5 sulfur-containing breakdown products, and phosphoric and hypophosphorous acids. A superimposed Congo red spray destroyed the fluorescence and resulted in dark blue spots against a red backgrovind. The sensitivity of this method is in the range of 0.2 to 5.0 μg, depending on the specific compound.

Turmeric (Curcuma longa), java turmeric (Curcuma xanthorrhiza) and cassumunar ginger (Zingiber cassumunar) are widely used in traditional Indonesian medicine. These three herbs have relatively similar rhizomes colour so it is difficult to be differentiated especially if they are in powder form. A rapid and reliable method, thin layer chromatography (TLC) fingerprint, has been developed in order to identify, authenticate and differentiate these three herbs through fingerprint profile of chemical compounds. TLC fingerprints of the three herbs were obtained by visualization of separate zones with visible and UV (254 and 366 nm) light. The TLC fingerprint pattern is different each other and showed a specific marker zones respectively. Therefore, TLC fingerprint can be utilized for identification, authentication and differentiation method in quality control of the three herbs tested.

The phytochemical screenings and analysis of chemical compounds in ethanol extract of labu siam fruit (Sechium edule Jacq. Swartz.) with Thin Layer Chromatography (TLC) has been carried out. Isolation was done by Soxhlet extraction for 6 hours with petroleum ether and the residue was extracted by maceration during 24 hours with ethanol.The isolated compounds in ethanol extract were identified by phytochemical screenings method and TLC. The result showed the presence of alkaloid, saponin, cardenolin/bufadienol and flavonoid.

A rapid method using thin-layer chromatography has been developed to measure urinary HVA (homovanillic acid). Ethyl acetate extracts of urine are chromatographed on glass plates coated with silica gel. The solvent used is the organic phase of benzene: acetic acid: water (2:3:1) mixture. The eluted HVA is treated with Folin's phenol reagent and absorbance is measured at 750 mμ in a spectrophotometer. Normal amounts of HVA in human urine are 8.23 ± 2.96 (mean ± standard deviation) mg/24 hours or 6.42 ± 2.28 mg/g of creatinine. Higher values were obtained in cases of ganglioneuroma and neuroblastoma, in a case of pheochromocytoma, and in one of two cases of hepatolenticular degeneration (Wilson's disease). In three cases of Huntington's chorea, values lay in the normal range.

Objectives: In this study, systematic pharmacognostic study and preliminary phytochemical screening of the bark of Cascabela thevetia L. were carried out. Methods: The selected plant part was collected, processed and stored in an airtight container. From the bark different pharmacognostic studies like macroscopic and microscopic evaluation, physicochemical parameters, fluorescence analysis were done. Powdered bark was successively extracted by petroleum ether, chloroform, ethyl acetate, and methanol using a Soxhlet apparatus and finally macerated with the hydro-alcoholic solvent system (30:70). The preliminary phytochemical analysis and thin layer chromatography of the extracts were done to find the nature and number of the different phytoconstituents present. Results: Transverse microscopy reveals the presence of crystal oxalate, cork cell, starch granules, vascular bundle, phloem fiber, parenchyma cells, and collenchyma cells. Powder microscopy also showed the presence of cork cell, fiber and calcium oxalate crystal. Results obtained in different physicochemical analysis like total ash, acid insoluble ash, water soluble ash, alcohol-soluble extractive, water-soluble extractive, and moisture content were 8.67%, 0.83%, 5.33%, 4.53%, 12.27%, and 7.83% respectively. Phytochemical analysis showed the presence of alkaloid, flavonoid, triterpenoid, phytosterol, tannin, saponin, anthraquinone, carbohydrate and fatty acid in the different extracts. TLC (Thin Layer Chromatography) study revealed 4 spots in petroleum ether, chloroform, ethyl acetate, and methanol extracts and 3 spots in the Hydro-alcoholic extract with different solvent systems. Conclusion: The results obtained from the study will provide a reliable basis for identification, purity, and quality of the plant.

Abstract Red Delicious apples were inoculated with Penicillium expansum NRRL 973 or P. expansutn 1071 (fresh apple isolate), and incubated in air at 33°F and in a controlled atmosphere of 1% carbon dioxide, 3% oxygen, and 96% nitrogen at 33°F. Both fungal strains produced the carcinogen, patulin, in the air-incubated lots, but only the freshly isolated strain (1071) produced detectable patulin in controlled atmosphere lots. Thin layer chromatography was used to assay ethyl acetate extracts of juice pressed from blended apple tissue. We conclude that naturally occurring P. expansum strains are capable of producing significant levels of patulin in apples stored from 3 to 6 months under controlled atmospheric conditions.
