Piceatannol (Compound 1), brownish white solids compound, is a stilbene compound has been isolated from methanol seeds extract of Corypha utan Lamk. Isolation and purification conducted by chromatographic methods. Structure elucidation deduced on the basis of spectroscopic data (UV spectrometer, FTIR, NMR and HRMS). MTT assay method of cytotoxicity activity showed that Compound 1 has a very strong cytotoxic activity against Murine leukemia P-388 cell lines with IC50 value 1.56 ppm. © 2015 Leny Heliawati et al.

A rust fungus of cinnamon trees is found throughout the year in Indonesia and seriously damages the trees, especially seedlings in nurseries. The causal rust fungus attacks leaves, petioles, shoots and young fruits. Morphological observations and inoculation experiments confirmed Aecidium cinnamomi is an endocyclic rust fungus. © 2015, Australasian Plant Pathology Society Inc.

The endophytic bacteria has an important role on the plant, such as a plant growth promoter with the production of plant growth regulators such as IAA and GA3, otherwise it can supply the plant nutrient. They are necessary for the growth and development of plants. The main objective of this study was to obtain effect of endophytic bacteria consortia from king of bitter as plant growth promoter Andrographis paniculata. This research used a randomized block design, 25 treatments and 3 replications. Treatment consisted of 1 control and 24 isolates of bacteria consortia. The results showed that 24 endophytic bacterial consortia were obtained that isolated from bitter plant. Endophytic bacteria consortia were contained in root tissues 105-106, shoot tissues 103-104 and stem tissues 103-105 CFU mL-1. In general consortia isolated from the root tissue had higher population than the leaves and stems tissue. The highest populations of endophytic bacteria consortia were produced by 5 MA (1.1x106). Endophytic bacteria consortia significantly increased growth, shoot (7.86%), roots (10-120%) and biomass dry weight. The highest percentage of growth plants were indicated by 5MD, 20BB, 20BD and 20CD, 100%, respectively. The highest number (6.5) and length of leaf (6.5 cm) at 5MD and width of leaf 20 MD (1.65 cm). The highest shoot dry weight in 20 BD (0.26 g plant-1), root (0.32 g plant-1) and biomass dry weight (0.54 g plant-1) in 20BA isolate. © 2013 Asian Network for Scientific Information.
