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.

The aim of the research was to examine the antifungal activity and the most effective concentration of teak bark (Tectona grandis Linn F) extract in inhibiting wood decay fungi Schizophyllum commune Fries. Teak bark was derived from BKPH Ledok, Sambong district, Blora Regency, West Java. The Teak bark made into particle with size pass of 40 mesh and retained 60 mesh. Then one kilogram of teak bark particle was maceration with 10 liter of aquadest. The extract then mixes with potatoes dextrose agar (PDA) with several concentration i.e. 0%, 0.25%, 0.5%, 0.75% and 1% and pour into petri dish. One isolate of Schizophyllum commune was put in the center of PDA in each petri dish then incubated for nine days. The bioactive compound of extract teak bark was evaluation used phytochemical screening. Result of the research showed that teak bark extract at concentration 0.25% and 0.5% has antifungal activity values was 27.98% and 40.38% and categorized as medium inhibition growth of S. commune. Meanwhile at concentration 0.75% and 1% the AFA values was 59.94% and 65.51% categorized as strong inhibition growth of S. commune. The bioactive compounds from phytochemical screening test were alkaloid, flavonoid, terpenoid, fenolik, antrakuinon, and saponin.

<p>Black cumin (Nigella sativa, L.) is a plant with a lot of advantages. Many research have been conducted on this plant and most of them use nonpolar, such as petroleum ether and chloroform, as a solvent in extraction process. In this research, extraction of black cumin using ethanol was applied.Black cumin extraction started with maceration using ethanol p.a. and partition using chloroform (1:1). The antioxidant activity of ethanol fraction of black cumin was examined by DPPH method. To identify the composition, phytochemical screening, including test for terpenoid, flavonoid, saponin, tannin and alkaloid, was also conducted.The result showed that the scavenging ability on DPPH method was 22.483% with IC50 2743.59. Phytochemical screening on ethanol fraction showed the presence of flavonoid, tannin and alkaloid. The study concluded that polar fraction of black cumin has small antioxidant activity.</p>

Bundung plants (Actinuscirpus Grossus) are widely spread in Borneo and used by society empirically as antimicrobials. Nevertheless, the use of Bundung plants as traditional medicine has not been equipped with convincing data, because there is no research that is related to the plants. In order to the use of the plants accountable, it is necessary to conduct research about phytochemical screening studies and tests the antimicrobial activity of ethanol extract of Bundung plants to staphylococcus aureusandEschericia Coli bacteria. Moreover, extraction does with maceration method. Secondary metabolite groups which are contained in the ethanol extract of Bundung plants were determined qualitatively using several of phytochemical reagents. The result of phytochemical screening test showed that ethanol extract of Bundung plants contains a group of secondary metabolites; namely flavonoid, tannin, saponin, phenolic, steroid and terpenoid. The method that was used to test antimicrobial activity to Staphylococcus aureusandEschericia Coli bacteria was a liquid dilution method with variations in extract concentration of 0,5%, 1%, 2%, 4% and 8% by considering at the clarity of each sample. The result of antimicrobial activity of liquid dilution to bacteria had inhibition at all concentrations and the biggest inhibitory activity was shown at concentration 8% with the clearest level and the MIC grade of the test is at a concentration of 1%. Based on the findings, it can be concluded that ethanol extract of Bundung plants has the potential of activities of an antimicrobial, especially from secondary flavonoid metabolites.

<p>Bligo (<em>Benincasa hispida</em>) merupakan tanaman yang tumbuh di daerah tropis dan subtropis. Buah bligo mengandung senyawa-senyawa aktif antara lain flavonoid, glikosida, karoten, vitamin, mineral, dan asam uronat. Penelitian di bidang farmakologi telah mengungkapkan bahwa buah bligo memberikan efek kesehatan, antara lain <em>antidepressant</em>, ansiolitik, antioksidan, antiinflamatori, diuretik, antidiabetik, dan antimikrobia. Namun penelitian di Indonesia mengenai kulit bligo masih sangat terbatas. Penelitian ini bertujuan untuk melakukan aktivitas antioksidan dan <em>screening</em> fitokimia pada kulit bligo. Kulit bligo dikeringkan kemudian digiling menjadi bubuk ukuran 100 mesh. Pengujian yang dilakukan adalah uji aktivitas antioksidan menggunakan DPPH, dan uji <em>screening</em> fitokimia kualitatif menggunakan LC-MS/MS QTOF. Aktivitas antioksidan pada kulit bligo adalah kelas medium dengan nilai IC<sub>50</sub> 6,91 mg/mL. Dari hasil analisis LC-MS/MS QTOF diketahui bahwa kulit bligo mengandung 36 senyawa, dengan 5 senyawa dominannya adalah adenosin; polidatin; 7-(4-hidroksi-3-metoksifenil)-l-(4-hidroksifenil)-4E,6E-heptadien-3-on; morasin C; dan kushenol S. Hasil karakterisasi yang diperoleh menunjukkan bahwa kulit bligo berpotensi sebagai senyawa aktif.</p><p><strong></strong><strong>Antioxidant Activity and Phytochemical Screening of Peel Bligo (<em>Benincasa hispida</em>). </strong>Bligo (<em>Benincasa hispida</em>) is a plant that grows in tropical and subtropical regions.
