Abstract:

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. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between good and excellent for dyed fabric.The results confirmed that natural dyes from Laccifer Lacca Kerr. extract have potential applications for silk fabric dyeing and producing ultraviolet (UV) protective silk fabric.

Abstract:

Laccifer lacca has generally been used as pigmenting, coloring agent and dying in chemical industry. Although, it has wide range of industrial applications, but inappropriately, due to lesser availability of data, it has been ignored. Keeping in mind, the wide application of Laccifer lacca, we tried to report the in-silico anti-cancer effects. The experimental techniques used to determine the structure was X-RAY diffraction. The reported resolution of this entry is 2.80 Å. Percentile scores (ranging between 0-100) for global authentication metrics of the record. In silico have a good pool to explore various parameters in molecular docking. We have performed in silico analysis of the active components of Laccifer lacca against the cervical, breast and lung cancer proteins and also found that lac extract enhances the production of anti-inflammatory markers and the increase is significant when compared to the standard vinblastine. It has been demonstrated by Lala and colleagues that a short lived molecule nitric oxide can result in the progression of human tumours. Therefore, the prominent antioxidant activity of phytochemical that can act as inhibitors of nitric oxide production can act as anticancer therapeutics. Both methanolic and aqueous extract shows significant anticancer effect on the hela, MCF-7 & A549 cells suggesting them as potential anticancer therapeutics for future. Keywords: Laccifer lacca, In-vitro & In-silico analysis, Carcinogenesis, Anti-inflammatory, Molecular Docking.

Abstract:

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.

Abstract:

Lac insect (Laccifer lacca Kerr) is phytophogus insect, that feed on Kesambi Tree (Schleichera oleosa Merr). During its life cycle, lac insect has been producing secretion in liquid form, known as LAK and having many uses, such as varnish/polish, food cover, drug capsule, cassette ribbon, etc. In 2005, Perum Perhutani has produced 60.547 kg LAK pellets, but has not fulfilled yet market demand. Cultivation technique is still conducted in a very sampling, and easy to be studied. Investment in developing lac insect is also profitable, and promising. There are two choices of management schemes in it cultivate, the first is by infecting lac insect to the host tree when the tree is 15 years old (project I) and the second is by infecting lac insect when the tree is 4 years old (project I). Financially, the Project II is more beneficial than Project I, so that the investment for project II is reasonable to be done.

Abstract:

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 “kabesak putih” and “kabesak hitam” plants.

Abstract:

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 silk fabrics have also been investigated.
