Abstract

The growth of the textile industry contributes significantly to environmental pollution from dye waste. The use of natural dyes from plants could be a solution to this problem, although they have weaknesses such as easy fading and less stable colors. Therefore, to improve color stability, a mordant is needed as a color fixative. Biomordants are mordants derived from plants that can be used as substitutes for metal mordants to bind dye to fabric fibers. Matoa leaves are one of the plants with the potential to be used as a biomordant because they contain tannin compounds. This study aims to determine the tannin content of methanol extracts of matoa leaf with various leaf age variations that can be used as a biomordant. The old and young matoa leaves were macerated with methanol for 3 days. The tannin content was determined using the Folin Ciocalteu method using a spectrophotometer Ultra Violet (UV) dual beam with positive control of tannic acid at a wavelength of 755.8 nm. The yield of methanol extract from old matoa leaves was 5.42% and from young matoa leaves was 8.58%. Phytochemical screening of methanol extract of old and young matoa leaves revealed the presence of secondary metabolite content of tannins, phenolics, flavonoids, saponins, triterpenoids, and alkaloids. The total tannin content of methanol extract from old matoa leaves was 0.37% ± 0.03, lower than that of young matoa leaves, which was 0.44% ± 0.06. Based on this research, it can be concluded that matoa leaves contain tannins and have the potential to be used as a biomordant.

Abstract

AbstractThe use of heavy-metal mordants in fabric dyeing is prohibited due to the resulting impacts such as environmental damage and public health, therefore environmentally friendly and non-toxic mordants such as tannin mordants (biomordants) are needed. Based on phytochemical screening on fern species (Pteridophyta), it is known that they contain tannins. However, scientific evidence of determining the total tannin content of various species of ferns has so far not been found. This study aims to determine the yield and total tannin content of methanol extracts of five fern species, namely paku kawat (Lycopodium cernuum), paku resam (Gleichenia linearis), paku dayak (Blechnum orientale), paku uban (Nephrolepis biserrata), paku miding (Stenochlaena palustris). Sample extraction was carried out by maceration method using methanol solvent. Extract yield was determined by weighing method. Analysis of total tannin content was carried out by UV-Vis spectrophotometric method at a wavelength of 755.8 nm using Folin-Ciocalteu reagent and sodium carbonate. The results of the research obtained the yield of methanol extracts on paku kawat, paku resam, paku dayak, paku uban, and paku miding are 11.271%; 8.389%; 4.810%; 3.615%; and 0.854%, respectively. Total tannin levels in methanol extracts of paku kawat, paku resam, paku dayak, paku uban, and paku miding were 0.024% ± 0.002; 0.256% ± 0.029; 0.272% ± 0.037; 0.143% ± 0.019; and 0.022% ± 0.012, respectively. Based on these data, it can be concluded that the methanol extract of paku kawat produces the highest yield while paku dayak produce the highest total tannin content. The results indicate that differences in fern species cause differences in tannin levels.

Abstract

The use of synthetic dyes as color enhancers or generators has caused various environmental and health problems. Plant tannin biomordants offer an alternative solution to address these issues. The sample used in this study were Cengkodok (M. malabathricum) plants that grow wild in places that get enough sunlight such as shrubs. Phytochemical screening on various parts of the cengkodok plant revealed that the highest tannin content is found in the leaf. However, until now there has been no scientific evidence that presents differences in tannin levels in cengkodok leaf with various types of solvents. This study aims to determine the yield and total tannin content of cengkodok leaf extract obtained through maceration process using methanol, ethanol, and ethyl acetate solvents. The extract yield was determined by comparing the weight of the dry extract with the powdered cengkodok leaf material. The total tannin content was analyzed using UV-Vis spectroscopy at a wavelength of 755.8 nm with Folin-Ciocalteu reagent and sodium carbonate. Tannic acid was used as a reference. The research results showed that the yield values for Cengkodok leaf extracted with methanol, ethanol, and ethyl acetate were 5.05%, 4.72%, and 1.59%, respectively. The total tannin content of cengkodok leaf extracts with methanol, ethanol, and ethyl acetate solvents was 0.47%±0.04, 0.37%±0.01, and 0.19%±0.04, respectively. Based on this research, it can be concluded that methanol is the most effective solvent in extraction and determination of total tannin content of Cengkodok leaf extracts.

Abstract

The use of metal mordants in fabric dyeing can harm the environment and health, so it is necessary to look for natural mordants that are more environmentally friendly. The utilization of Simpur Air leaves (Dillenia suffruticosa) as a biomordant is one of the efforts to produce a more environmentally friendly tannin mordant. D. suffruticosa has been reported to contain tannin compounds in all parts of the plant. However, scientific evidence of differences in the total tannin content of methanol extracts of D. suffruticosa leaves with various extraction methods have not been found so far. This study aims to determine the effect of different extraction methods on the yield value and total tannin content of methanol extracts of D.suffruticosa leaves using UV-Vis spectrophotometric method at a wavelength of 755.8 nm with Folin Ciocalteau reagent. D. suffruticosa leaves are extracted by using three methods, namely maceration, soxhletation and reflux. Tannic acid is used as a comparator. The results show that the yield value of D. suffruticosa leaves extracted by maceration, soxhletation and reflux methods were 8.35%; 12.26%; and 25.24%, respectively. The total tannin content of methanol extract of D. suffruticosa leaves with maceration method is 0.15% ± 0.007; soxhletation is 0.18% ± 0.007 and reflux is 0.21% ± 0.016.  Based on the results of the data analysis, the significance value <0.05 was obtained. It can be concluded that the extraction method affects the yield value and total tannin content of methanol extract of D. suffruticosa leaves.
