Raw-consumed vegetables, known as lalapan, is famous among Sundanese community in West Java because of their heath benefits. In the present study, nine selected raw-consumed vegetables, namely Vigna unguiculata, Ocimum tenuiflorum Linn, Psophocarpus tetragonolobus, Etlingera elatior, Abelmoschus esculentus, Oenanthe javanica, Centella asiatica, Pluchea indica and Pilea trinervia were screened for their antibacterial and cytotoxic activity. Antibacterial activity test were conducting using disc diffusion method against Serratia marcescens, Escherichia coli, Enterobacter cloacae. Whereas, the cytotoxic activity were examined using WST assay against lung cancer cell line A549. For the antibacterial activity, this study finds that Ocimum tenuiflorum, Etlingera elatior and Pluchea indica have highest inhibition zone against tested bacteria. Furthemore, the results of the cytotoxicity assay indicated that among the nine plants tested, five plants showed IC50 \< 20 μg/mL, including Vigna unguiculata, Ocimum tenuiflorum Linn, Etlingera elatior, Centella asiatica and Pilea trinervia with the IC50 value 13.71 μg/mL, 7.43 μg/mL, 12.45 μg/mL, 5.51 μg/mL and 18.84 μg/mL respectively.

Introduction: Bulian wood (Eusideroxylon zwageri) known as iron wood. It was known as wood source which fungi and insect resistant. These effects were interconnected with secondary metabolites contained within. Methods: Eusideroxylon zwageri wood powder was macerated with methanol and fractinated with n-Hexane, dichloromethane, ethyl acetate. Eusiderin I and Compound B were isolated from n-hexane fraction, while Compound C were isolated from dichloromethane fraction. Eusiderin I, compound A and Compound B were characterized using melting point, UV spectroscopy and compared with previous data. Antifungal activity test was conducted with Microsporum gypseum using paper disc method. Results: A research on antifungal activity of Neolignan derivatives from Eusideroxylon zwageri against pathogenic fungus Microsporum gypseum had been carried out. Eusiderin I, Compound B and Compound C were isolated from wood of Eusideroxylon zwageri. All three compounds are white crystals with melting point in such 99-100 oC, 110-112 oC, 98-99 oC, respectively and UV spectrum data is similar to reference. The antifungal activity test of Eusiderin I, Compound B and Compound C from Bulian wood (Eusideroxylon zwageri) to phatogen fungus of Microsporum gypseum showed that with five different concentrations (5, 25, 50, 100 and 200 ppm), Eusiderin I was a potent antifungal because it had a strong activity in inhibiting the Microsporum gypseum growth. The 5 days incubation test result showed that 50 ppm Eusiderin I could inhibit the Microsporum gypseum colony growth. The 100 ppm Eusiderin I gave the most effective inhibition precentage because it could inhibit the Microsporum gypseum colony growth (= 93.9\%). Conclusion: Based on this data, Eusiderin I can be indicated an antifungal candidate.

Background: Cassia fistula L. has been traditionally used to cure skin diseases. That disease can be caused by various bacteria, such as Propionibacterium acnes and Pseudomonas aerugniosa. Objective: the objective of this research was to formulate cream containing active fraction of Cassia fistula bark and to study the antibacterial activity as well as physical stability of the active substance after formulation. Materials and Methods: The cream base were oilin- water (O/W) and water in oil (W/O) type. Antibacterial activity test had been performed by using agar diffusion method. Determination of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were conducted by microdilution method. The active fraction was formulated into creams with concentration of 4 -6x MIC. Physical evaluation of creams including organoleptic, pH, viscosity, TLC (Thin Layer Chromatography) profiling and antibacterial activity against both tested bacteria were evaluated during 28 days of storage. Results: The results showed that ethyl acetate fraction was the most active, having MIC and MBC values of 175 and 350 ppm respectively against P. acnes, while those against P. aeruginosa were 400 and 800 ppm. Optimation on creams using different type of cream bases showed that either O/W or W/O creams remained stable during 28 days of storage in terms of organoleptic and pH. The viscosity increased in O/W and decreased in W/O type. Qualitative analysis by TLC profiling showed that the ethyl acetate fraction of Cassia fistula as chemical compounds in creams was relatively stable as the profile remained the same after 28th day of storage. Result of antibacterial activity test on cream with O/W base was unchange after 28 day, while that with W/O revealed no activity which may due to poor diffusion within the cream base as media. Conclusion: active fraction of Cassia fistula can be formulated into cream with O/W cream base system.
