“…To examine absorbance properties of L. deliciosus and L. sanguifluus crude extracts, the adsorption UV-Vis spectra were measured and the obtained spectra in full UV-Vis range are presented in Figure 3. The absorption spectra of natural dyes from L. deliciosus and L. sanguifluus in the present study found to be between 250 and 400 nm for azulene and its derivatives as in the study of Matênovâ et al (2014) [50]. It is thought that major colorants in the edible Lactarius species could be azulene and its derivatives.…”

In recent years, the use of synthetic dyes and pigments in textile finishing companies has been discussed for their harmful effects on human health and environment. For this reason, the use of plant-based dyestuffs from the nature has begun to increase because of the biodegradability, nontoxicity, human health and waste water contamination. Natural dyes are substances synthesized by some plants, animals, lichens and fungi in nature. Fungal species, including lichenized fungi have been used as natural colorants in different parts of the world throughout the history. In this study, natural dyes were extracted from Lactarius deliciosus and Lactarius sanguifluus collected from Osmaniye province (East Mediterranean region) of Turkey. The adsorption UV-Vis spectra of the mushrooms were measured to examine major colorants, and FTIR analysis of natural dyes obtained from the mushrooms extracts was performed. According to the analyses, major colorants in the edible Lactarius species could be azulene and its derivatives. Wool yarn (for carpet) was dyed with these natural dyes by using different mordants. CIELab (L*, a*, b*, c* and h), color differences (ΔE) and color strength (K/S) values of dyed wool yarns were determined. According to the dyeing results, cream and brown colors were obtained from L. deliciosus and L. sanguifluus respectively; the use of mordant (ferrous sulfate) increased the color strength of dye goods. Besides, properties of rubbing and washing fastness were investigated, and the results of the dyed yarns were low/moderate. This is the first study on dyeing of wool yarns with natural dyes obtained from L. deliciosus and L. sanguifluus collected from East Mediterranean (Osmaniye province) of Turkey.

“…According to the previous research by Beigi et al [ 41 , 67 , 75 ], peppermint, yarrow and chamomile are herbs with high contents of terpenes, terpenoids and phenolic compounds, which was confirmed by the peak registered at the 270 nm and as a band for 290–320 nm [ 90 , 91 , 92 ]. The chlorophyll content characteristic for plants was noticed as an extensive peak in the range of 360 to 450 nm and at 680 nm [ 93 ].…”

In this study, peppermint (Mentha piperita L.), German chamomile (Matricaria chamomilla L.) and yarrow (Achillea millefolium L.) were applied as natural fibrous fillers to create biocomposites containing substances of plant origin. The purpose of the work was to investigate the activity and effectiveness of selected plants as a material for the modification of natural rubber composites. This research was the first approach to examine the usefulness of peppermint, German chamomile and yarrow in the field of polymer technology. Dried and ground plant particles were subjected to Fourier transmission infrared spectroscopy (FTIR) and UV–Vis spectroscopy, thermogravimetric analysis (TGA), goniometric measurements (contact angle) and scanning electron microscopy (SEM). The characterization of natural rubber composites filled with bio-additives was performed including rheometric measurements, FTIR, TGA, cross-linking density, mechanical properties and colour change after simulated aging processes. Composites filled with natural fillers showed improved barrier properties and mechanical strength. Moreover, an increase in the cross-linking density of the materials before and after the simulated aging processes, compared to the reference sample, was observed.

“…The azulene molecule consists of two condensed rings, cyclopentadiene and cycloheptatriene, and possesses 10π electrons, so it obeys Hückel's rule. Moreover, azulene with its deep blue color is isomeric with colorless naphthalene and intensively absorbs light in the range of 500-700 nm [17,18].…”

Azulene is an aromatic hydrocarbon that possesses a unique chemical structure and interesting biological properties. Azulene derivatives, including guaiazulene or chamazulene, occur in nature as components of many plants and mushrooms, such as Matricaria chamomilla, Artemisia absinthium, Achillea millefolium, and Lactarius indigo. Due to physicochemical properties, azulene and its derivatives have found many potential applications in technology, especially in optoelectronic devices. In medicine, the ingredients of these plants have been widely used for hundreds of years in antiallergic, antibacterial, and anti-inflammatory therapies. Herein, the applications of azulene, its derivatives and their conjugates with biologically active compounds are presented. The potential use of these compounds concerns various areas of medicine, including anti-inflammatory with peptic ulcers, antineoplastic with leukemia, antidiabetes, antiretroviral with HIV-1, antimicrobial, including antimicrobial photodynamic therapy, and antifungal.
