Silk fabric was dyed with the colourant extracted from Laccifer Lacca Kerr. by using post-mordanting process and pad-dry technique. The effect of metal mordantats at different mordant concentration levels on their colour strength was also investigated. Silk fabrics dyed with Laccifer Lacca extract showed a light pink shade, while those dyed with alum and stannous chloride produces pinkish-red colour. Silk mordanted with CuSO4 gave a purple red colour, while those dyed with FeSO4 had a reddish-gray colour. The fastness properties ranged from fair to good, while washing fastness was poor level.

Abstract A new method has been proposed for detection of lac color in food. Lac color is a natural color additive derived from a secretion of the insect Coccus Laccae (Laccifer lacca Kerr). It is extracted from food with methanolic oxalic acid and eluted from a column of Amberlite XAD-2 with the same solvent. The fraction containing the lac color is treated with diazomethane to produce 2 reddish-orange markers. The marker species in the reaction mixture are detected by both thinlayer chromatography and reverse-phase liquid chromatography.

Lac insects (Laccifer lacca Kerr) live parasitically on “kosambi” plants, and produce resins that are called lac. Lac are used for electronics, printing, textile, clothing, cosmetics, and food industry. The insects also live on various plants. The goal of this research was to evaluate the population quality of Lac insect that live on three host plants. The best parameter for population quality was biomass or lac production. Three host plants were inoculated by broods. The result showed that “kosambi” was the best host plant for the insect due to higher biomass (i.e lac production) than “kabesa

Cold-pad-batch technique of silk dyeing fabric with two natural dyes (Laccifer lacca Kerr. And Garcinia dulcis (Roxb.) Kurz bark) using pre-mordant are performed using 3 different mordants namely, alum, tartaric acid and ferrous sulfate. The study showed that color intensity (K/S) slightly increased when the batching time increased from 1 to 24 hours. Dyed silk fabrics have different color shades depending on the types of mordant applied. Ferrous sulfate and alum was found to be the best mordants for improvements of color depth. Various fastness properties (wash, crock and light) of the dyed s

Lac is one of the most important non-timber forest products and massively cultured in East Nusa Tenggara. It is the resinous secration of lac insects(Laccifer Lacca Kerr) which serves as a shield to protect the insects themselves from their enemy. Parasites and predators of the lac insert are the major problem associated with lac culture and hence potentially decrease lac production significantly. This study identified parasites and predators of the lac insect attacking cultures of lac in East Sumba, East Nusa Tenggara. Samples of insects were collected in March 2007 fromHambapraing, Mbatakapi

Atisaar is a very commonly found disease in all age groups. It is colloquially called diarrhoea, a prevalent clinical feature of acute and chronic inflammation of the gastrointestinal tract. The line of treatment depends on the type and stage of the disease. In Ayurveda, Atisaar is classified based on the vitiation of Dosha, while in modern medical science, it is based on the type of causative organism. There are so many formulations used to treat diarrhoea in Ayurvedic texts. Lipid-based formulations of Shadanga Ghrita include ingredients such as Kutaj (Holarrhena antidysenterica Wall), Daruh

Background: Laccifer lacca (Kerr) produces a mixture of polyhydroxy anthraquinones (laccaic acid) known as lac dye. Literature suggests that these laccaic acids have its structural resemblance with the anticancer drug Adriamycin (ADR). Hence, it may possess potential anticancer activity. Method: This study was designed to explore the in vitro anticancer activity of the three fractions of lac dye, i.e., chloroform (C), methanol (M) and water (W) fractions and isolation of constituents from bioactive fraction.

Abstract Background Lac color, a natural red dye derived from the larvae of laccifer lacca kerr, is one of the most commonly used substances in food. To date, no studies have reported on the antigenicity of lac color and the other biomarkers that can determine anaphylactic reactions. To address this, we evaluated the antigenicity of lac color through active systemic anaphylaxis (ASA) in addition to identifying potential biomarkers performing exploratory studies. For ASA test, Guinea pigs (n = 5) were sensitized with 0(negative control), 4 mg/kg of lac color, 4 mg/kg of lac color + FCA, and 5 m

Objective: Lac is derived from Laccifer lacca Kerr and has historically been used as a dye due to its coloring qualities. It is now widely utilised in the food and colouring indus-tries. Lac dye was isolated for the first time with the help of preparative HPLC. Further char-acterization was also performed using NMR and MS spectroscopy techniques. Methods: The column used for the isolation was the Inertsil ODS-3 reverse-phase C18 column. The wavelength of the PDA detector was set between 275 nm and 410 nm. Data acquisition was carried out for Empower 2.0 (Waters Ltd., United States). For the mo
