Abstract

Rendeu (Staurogyne elongata (Neese) Kuntze) is a native Indonesian plant used as food and traditional medicine in the daily life of the people residing around Gunung Halimun-Salak National Park. Due to the potential source of herbal-based medicines and traditional food in the long-run purposes, the proper method of its propagation is required, so that Rendeu can be conserved and utilised sustainably. This study employed two research designs. First, a completely randomized design with pruning and IAA (indole-3 acetic acid) treatment was used for seedling growths. Second, plant propagation applied a factorial randomized block design: planting media types and plant growth regulator (PGR) (rootone F) treatment. Observation included the number of buds, number of leaves, number of flowers, plant biomass, root length, and relative chlorophyll content using the SPAD tool. The data were analysed using ANOVA (SPSS ver. 17.0), followed by Pearson correlation analysis. The results showed that applying IAA and leaf pruning could increase the number of buds, the number of leaves and the fresh weight of S. elongata plants compared to the control plant. The addition of rootone increased the growth of Rendeu shoot cuttings, shown in all growth parameters and chlorophyll content. Humus was the best media for Rendeu’s growth among all planting medium.  Planting media affected the increase in the number of leaves and the number of buds of S. elongata significantly. The interaction of planting media and PGR somewhat influenced root length and total leaf chlorophyll. The growth and production of S. elongata increased with the time of planting.

Abstract

Cinnamomum burmanni (Lauraceae) is one of the Cinnamomum species native to Indonesia. Given the worldwide use of cinnamon, the famous spice derived from its bark, cinnamon is also considered to possess medicinal properties. Consequently, a comprehensive review of C. burmanni was conducted to explore its medicinal benefits. This paper reviews several studies on the traditional use of C. burmanni in Indonesia, its phytochemistry, and its pharmacological properties. Traditionally, C. burmanni is utilized not only as spices but also for medicinal purposes, food ingredients, and ritual purposes. The bark is the most commonly used part, while few other parts of the plant are used. Several phytochemical compounds of C. burmanni have been identified. C. burmanni also has been reported to exhibit a wide range of biological activities. From those studies, it can be concluded that the medicinal use of C. burmanni’s bark has been scientifically validated due to its rich content of active compounds. Furthermore, other parts of C. burmanni should be analyzed to determine their content of active compounds. Keywords: active compound, Cinnamomum burmanni, medicinal plant, spice, traditional medicine

Abstract

Marine algae is a biological source that is rich in bioactive activity. Marine algae is an important source of macronutrients, especially proteins and lipids, as well as micronutrients such as vitamins and minerals along with dietary fiber and other minoritarian constituents such as polyphenols. This study aimed to determine the antioxidant of hydrolysate protein of Sargassum sp. as. The work method was started by collecting Sargassum sp. in the intertidal zone of the South Coast of Gunungkidul, Yogyakarta and then brought to the laboratory for extraction. Protein hydrolysate was obtained by protein extraction using phosphate buffer and triRNA kit. Several buffers was used to optimize the extraction, namely PBS buffer, Tris HCl buffer and plant extraction buffer The protein obtained were evaluated in the SDS-PAGE electrophoresis. The isolated protein subjected for the trypsin digestion to obtain the hydrolysate protein then followed by antioxidant assays using DPPH test. Data analysis was carried out using ANOVA statistics for the antioxidant test. Several ratios of trypsin and protein are used to find the optimal ratio to produce protein hydrolysate. From the result it was observed that the best buffer solvent to use was Tris HCl buffer for the isolation of Sargassum sp. This can affect the protein profile of the Sargassum sp protein hydrolysate. by producing higher protein precipitates than other buffer types.

Abstract

Castanopsis argentea is a potential souce of natural antibiotics that has not been studied much. The purpose of this study was to analyze the antibacterial activity and study the content of secondary metabolites from leaves and twigs extract of Castanopsis argentea against Escherichia coli and Staphylococcus aureus bacteria. This study used the paper disk method to see antibacterial activity. Antibacterial activiy was indicated by the formation of a clear zone around the dic paper. Samples were made into three treatments, namely the concentration of 20 mg/ml; 40 mg/ml; and 80 mg/ml. the solvent used was selected based on the level of polarity namely ethyl acetate, 70% ethanol, and aquades. The results of the antibacterial activity test showed that the extract with the most potential to inhibit bacterial growth was ethyl acetate twig extract at a concentration of 80 mg/ml with an average diameter of 6mm for Escherichia coli bacteria and 8.67 mm for Staphylococcus aureus bacteria. The compounds identified in the ethyl acetate twig extract are terpenoids, phenolics, and flavonoids. The results of profiling using UV-Vis spectrophotometry showed that the maximum absorption of terpenoids, flavonoids, and phenolics compounds was found in the wavelength range of 300-600 nm. The secondary metabolite compounds contained in the leaf and twig extracts of Castanopsi argentea make this species a potential natural antibacterial.
