Abstract

Teak (Tectona grandis L.) is a plant with strong wood and is resistant to pests and diseases. In addition, its leaf extract is widely used by public as an additive in foods both as a preservative and as an alternative food coloring. The objective of this research was to determine phenolic compounds of teak leaves extracted with three different decomposition times (one, two and three weeks of decomposition). Extraction was conducted by using maceration method in which water was used as solvent. Identification of Phenolics was done by using Gas Chromatography. The results showed that the compounds of vanilic acid, salicylic acid, ferulic acid, cumaric acid, gallic acid, benzoic acid and cafeic acid were identified in the analysis. The concentration and composition of phenolic compounds in the extract was determined by decomposition.

Abstract

The purpose of this research was to induce polyploidy on Impatiens balsamina L. Seedlings of I. balsamina was immersed in 0,01% colchicines solution for 4, 6, 8, and 24 hours. Chromosome of I. balsamina was visualized using squash method stained with aceto-orcein. Morphological observations were conducted on plant height, stem circumference, leaf length and width, number of branches flowering time and size of flower. The result revealed that 0,01% solution of colchicine was able to induce polyploidy on I. balsamina. Obsevation on morphological characteristic showed that colchicine treatment increased plant height, stem circumference, leaf length and number of branches. Colchicine treatment induced earlier flowering time, but flower size was unaffected. Twelve chromosomes (2n = 2x = 12) were observed in the diploid seedlings while 25 chromosomes were observed in the tetraploid (2n = 4x = 24 seedlings.
