Katuk leaves are known as vegetables that are rich in nutrients in several regions in Indonesia. In addition, it has the potential as an herbal medicine that needs to be developed based on its chemical compound content. The groups of chemical compounds contained in plants can be analyzed using a phytochemical screening test. Phytochemical screening was carried out on katuk leaf extract samples obtained through the maceration method using methanol solvent which was then concentrated using a rotary evaporator. Phytochemical screening test consisted of phenolic, tannin, flavonoid, saponin, triterpenoid, steroid, and alkaloid screening. Furthermore, the test results will be used as a basis for researchers in developing the potential of katuk leaves as herbs to reduce fat content in poultry product. The class of compounds, especially flavonoids, saponins, and tannins has a role in reducing fat accumulation. The test results showed  that the positive katuk leaf extract contained moderate amounts of phenolic compounds, tannin, flavonoids, saponins, triterpenoids, and alkaloids. That is, katuk leaves have the potential as an herb that can reduce fat levels in poultry products.

This study was started by extraction of Eucalyptus deglupta Blume. Using organic solvent   (n-hexane, ethyl acetate, ethanol and water) followed by phytochemical screening and toxicity test using Brine Shrimp Lethality Test (BSLT) method. Isolation and identification of chemical compounds contained in the fraction were done by column chromatography and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Phytochemical screening revealed the presence of alkaloids, flavonoids, steroids and phenolics in the extract. Toxicity test results showed that the ethyl acetate extract was potentially active with LC50 value of  617.95 ppm. The extract was continued to isolation stage and gave fraction EKEA-3.1 with LC50 value of 2759.93 ppm. Identification of chemical compounds in EKEA-3.1 with KG-MS analysis showed that EKEA-3.1 was suspected to be Stigmastan-3,5-diene.

Wood vinegar rice husk contains a chemical compound that can be used as a biopesticides. Wood vinegar contained compounds which estimated potential as repellent, antifeedant, antimicrobials, antioxidants, disinfectants and as preservatives. The content of chemical compounds in the wood vinegar must be identified. Identification were done by calculating the concentration of acid, phenol and an infrared spectrophotometer. Production of wood vinegar made by the pyrolysis process used pirolisator. Most of the wood vinegar obtained is evaporated using a rotary evaporator and partly extracted using the method of separating funnel. Compound of acid and phenol in wood vinegar evaporation were higher than the extraction of wood vinegar. These results were confirmed by an infrared spectrophotometer spectrum showed the functional groups of acid and phenolic compounds. Keywords: wood vinegar rice husk, acid, phenol, pyrolysis, infrared spetrofotometer

Pineapple (Ananas comosus (L.) Merr) is one type of fruit that is in demand by the community, both local and world. Pineapple has a waste part that is skin. Pineapple skin in Indonesia is generally just thrown away as waste, whereas pineapple skin contains chemical compounds that are known to have properties. The purpose of this study was to determine secondary metabolite compounds found in pineapple skin. This type of research is descriptive qualitative. Then the method used is phytochemical analysis. The Positive test of this method is characterized by a change in color. Pineapple skin samples were taken from Samarinda, East Kalimantan. The extract was carried out by maceration of dry samples using 96% ethanol solvent. The results of the pineapple skin extraction are then carried out phytochemical screening tests using certain reagents. Phytochemical screening tested included flavonoids, alkaloids, steroids, triterpenoids, tannins, phenolics, and saponins. Based on the results of phytochemical screening research, positive pineapple skin extracts contain flavonoids, alkaloids, tannins, and saponins, while negative results contain phenolic compounds, steroids, and triterpenoids.

ABSTRACT This research analyzed the major chemical constituents present in the ethanolic extract of the leaves of Bridelia montana (ROXB) WILLD. The leaves of Bridelia montana were collected, powdered, de-fatted with n-hexane and then extracted with 90%ethyl alcohol. Preliminary phytochemical screening of the ethanolic leaf extract of Bridelia montana showed the presence of chemical constituents like alkaloids, glycosides, phenolic compounds, tannins and resins. HPTLC fingerprint analysis of the extract was carried out using CAMAG HPTLC system equipped with Linomat 5 sample applicator, UV cabinet and WIN-CATS-4 software. The results from HPTLC fingerprint analysis of the ethanolic leaf extract of Bridelia montana revealed the presence of 6 polyvalent constituents.

Kopasanda (Chormolaena odorata) leaves are often used as traditional medicine and are proven to be used as natural antiseptics. We use this public belief as the basis for analyzing the antiseptic content in laboratory tests. The test results are then used as the basis for making the gel. The method we use is the maceration method to proceed to the phytochemical screening test. Based on the results of the analysis, it can be concluded that, it is true that Kopasanda leaves (Choromolaena odorata) contain antiseptic compounds that can heal wounds.
