The natural dyes separated from plants are of gaining interest as substitutes for synthetic dyes in food and cosmetics. Thespesia populnea (T. populnea) is widely grown plant and used in the treatment of various diseases. This study was aimed to separate natural dye from T. populnea bark and analysis of its dyeing property on different fabrics. In this investigation pharmacognostic study was carried out. The pharmacognostic study includes morphological study, microscopical examination, proximate analysis along with the phytochemical study. The dyeing of different fabric was done with a natural dye extracted from T. populnea bark. The fabrics like cotton, butter crep, polymer, chiken, lone, ulene and tarakasa were dye with plant extract. The various evaluation parameters were studied. It includes effect of washing with water, effect of soap, effect of sunlight, effect of alum, effect of Cupric sulphate, microscopical study of fabrics and visual analysis of dyeing by common people were studied. In results, natural dye isolated from T. populnea bark could be used for dyeing fabrics with good fastness properties. The studies reveals that, the dyeing property of fabrics after washing with water and soap, exposed to sunlight does not get affected. It was observed that cotton and tarakasa stains better as compared with other fabrics. It was concluded that the ethanolic extract having good dyeing property.

Plumeria obtuse L. (Apocynaceae) is an ornate outdoor plant. The plant was traditionally used during accidentalinjuries. However, the pharmacognosy of this plant is very poorly explored. Therefore, we have conducted this study to assess the distinctive qualities of the P. obtusa. To investigate P. obtusa seed pods’ preliminary pharmacognostic, physical-chemical, phytochemical, microscopic, and phytoconstituent potential. Initially, the shape and microscopic characteristics of plant seed pods were assessed. Physicochemical analysis was used for the standardization. Utilizing several chemical techniques, phytoconstituents were evaluated qualitatively. This was followed by quantitative estimation and analytical profiling of various phytoconstituents. The basic characteristics of the seed pod have been documented by macroscopy to be its brown color, sweet aroma, bitter flavor, coarse texture, and rough fracture. Microscopy showed the existence of vascular bundles, lignified fibers, calcium oxalate crystals and arteries. The results of the physicochemical analysis revealed no foreign organic matter, 2.8 % weight-average moisture content and a high total ash value of 14.80 compared to an acid insoluble ash value of 0.70, which indicated that there was less inorganic matter in the plant. The extractive values were 3.93, 6.03 and 10.16 % w/w for water soluble, alcohol soluble and hydro-alcoholic soluble extracts respectively. Flavonoids, glycosides, saponins, phenolic constituents, tannins and carbohydrates were found during early phytochemical analysis. Instrumental analysis has given an idea about functional groups present whereas GCMS technique helped in identification of phytoconstituents. The results of this study can be significantly used as a reference support for quality control and standardization of P. obtusa and preparation of a monograph of plant.

Cosmetics have lured mankind from time immemorial. Colourant cosmetics have secured a respectable space at the dressing table or salon for their various benefits. Capsicum is widely cultivated across the globe for its pungent principle, capsaicin or capsanthin. However, the bright colour pigments are often neglected due to its pungency. Lycopersicon (tomatoes) also are rich in red colour because of the pigment lycopene. Objective of the current study was to integrate red pigments isolated from capsicum and lycopersicon fruits into lipstick. Major challenge was to nullify the pungency of the capsicum oleoresin. Lipstick bases were formulated using various combinations of waxes and fats. The capsicum oleoresin was treated with NaOH 10 % w/v to nullify the pungency. Lycopene rich extract was obtained from dried tomatoes and later incorporated into the lipsticks bases. The formulated sticks were evaluated and compared against the marketed lipsticks. Our findings reveal that both the lycopene and capsicum oleoresin rich extracts can be conveniently incorporated into the lipsticks and can prove to be a better natural and vegan substitute for synthetic carcinogenic dyes.

Herbal medicines are the first type of medical system ever developed for treatment. The increasing studies on medicinal plants influenced the construction of an unique herbal pharmacopoeia and transformed how it was processed and administered. The pharmacognostic study of plants is an important parameter for quick identification and authentication of plants with less time and cost. Impatiens balsamina (Balsaminaceae) was commonly called garden balsam or rose balsam, native to India and Myanmar. The studies were carried out to evaluate different parameters, including macroscopy, microscopic characters and physicochemical parameters, by performing standard procedures. The detailed characteristics of leaf, stem and root with intensive quantitative microscopy were performed. In physicochemical analysis, various parameters like ash values, foreign organic matter, extractive values, foaming index and loss on drying were performed. In the current study, pharmacognostic factors for quick plant identification and authentication macroscopic and microscopy were investigated, which will be helpful for further research on plant.
