“…The differences in tannin concentration in the extracts obtained with the four ethanol concentrations reflect the significant influence of the solvent, and can be explained with the different selectivity of water-ethanol mixtures used in the extraction of bioactive molecules. The same pattern of the influence of process temperature, duration and ethanol concentration on the content of tannins in liquid extracts has been reported in other studies on essential oilbearing and medicinal plants, such as tobacco [15], mint [16], thyme [17], and rosemary [18].…”

Introduction. The aim of research is to characterize the chemical composition of physalis leaves and the obtaining of extracts rich in bioactive compounds intended for medical and cosmetic applications. Materials and methods. Extraction of dried physalis leaves was carried out under the following conditions: hydromodule-1:10 (w/v), solvents-95, 70, 50 and 30 vol.% ethanol, temperature-20, 40and 60°C, and duration-1, 3 and 5 h. The content of polyphenols, flavonoids and triterpenes in the leaves and in the obtained extracts was determined by HPLC. Results and discussion. The analyzed physalis leaves from variety Plovdiv and from the bio-farm were with 8.32% and 8.79% moisture, respectively. The plant materials contained 9.62% and 10.58% tannins, respectively. Extract color varied by solvent concentration: yellow-orange (with 30% ethanol), yellow-brown (50% ethanol), green-brown (70% ethanol), and brown (95% ethanol). The experimental data and the derived equations showed that the two main factors-temperature and duration, had a strong influence on the content of extracted tannins. The optimal conditions of the process were: 5-hour extraction at a temperature of 60С, with 30 and 50% ethanol for the leaves from Plovdiv genotype, and with 50 and 70% ethanol-for the bio-farm genotype. Twelve phenolic acids were identified in the leaves and extracts from Plovdiv genotype and 10-in those from the bio-farm genotype. Rutin was the dominant flavonoid in the leaves and extracts from both genotypes. The major triterpene in the leaves and in the extracts was oleanolic acid, followed by betulin. The extracts from physalis leaves are rich in bioactive substances (phenolic acids, flavonoids and triterpenes), and have the prospective for possible application in medicinal and cosmetic products. Conclusions. This study provides for the first time data about the optimal conditions for the extraction of Physalis peruviana leaves, as well as information about the content of certain biologically active components in the leaves and in the obtained extracts. These are the first results reported about physalis genotypes grown in Bulgaria.

“…Cosmetic products deteriorate due to the oxidation of their fatty components by fungi and bacteria. The microorganisms that represent the most frequently occurring microflora in cosmetic and food products are the Gram-positive bacteria Bacillus subtilis, Staphylococcus epidermidis, and Staphylococcus aureus; the Gram-negative bacteria Pseudomonas aeruginosa, Escherichia coli, and Salmonella abony; the yeasts Saccharomyces cerevisiae and Candida albicans; the mold Aspergillus niger [63]. For this reason, for more than two decades, trials have been carried out using extracts and essential oils of rosemary as bactericidal and antifungal agents in cosmetic preparations [64].…”

Rosmarinus officinalis L. (Rosemary): An Ancient Plant with Uses in Personal Healthcare and Cosmetics

2020

This work is a bibliographical review of rosemary (Rosmarinus officinalis) that focuses on the application of derivatives of this plant for cosmetic products, an application which has been recognized and valued since Ancient Egyptian times. Rosemary is a plant of Mediterranean origin that has been distributed throughout different areas of the world. It has many medicinal properties, and its extracts have been used (mainly orally) in folk medicine. It belongs to the Labiatae family, which contains several genera—such as Salvia, Lavandula, and Thymus—that are commonly used in cosmetics, due to their high prevalence of antioxidant molecules. Rosemary is a perennial shrub that grows in the wild or is cultivated. It has glandular hairs that emit fragrant volatile essential oils (mainly monoterpenes) in response to drought conditions in the Mediterranean climate. It also contains diterpenes such as carnosic acid and other polyphenolic molecules. Herein, the botanical and ecological characteristics of the plant are discussed, as well as the main bioactive compounds found in its volatile essential oil and in leaf extracts. Afterward, we review the applications of rosemary in cosmetics, considering its preservative power, the kinds of products in which it is used, and its toxicological safety, as well as its current uses or future applications in topical preparations, according to recent and ongoing studies.

“…Rosemary is native to Europe and North Africa along the Mediterranean coast and is now widely cultivated in many countries in Europe, North America and China [1][2][3]. Rosemary hydrosol has a natural rosemary fragrance, which can be used as a raw material for the production of cosmetics or facial masks [4]. It has antioxidant [5,6], antibacterial [7,8] and other effects.…”

A combined dispersed liquid–liquid microextraction (DLLME) and chromatography (GC) method was developed for the determination of 24 aromatic substances in rosemary hydrosol in this work. The pretreatment method of DLLME was optimized by carefully selecting the appropriate extraction agents, dispersants, and their respective amounts. With carbon tetrachloride as the extractant and acetone as the dispersant, the enrichment factor of DLLME is 13.3, and the 24 target substances such as eucalyptol, camphor and verbenone can be separated within 31 min and quantified by an external standard method using gas chromatography (GC). The correlation coefficient r2 of the linear regression equation is within the range of 0.9983 to 0.9991. The detection limit of the method was 0.02 mg/L, the recovery rate of the spiked solution was 76.4–118.4%, the relative standard deviation was 0.4–6.9% and the method was used to detect the semi-finished products of rosemary hydrosol and the finished rosemary hydrosol sold on the market. This method also provides a reference for the qualitative and quantitative determination of aromatic substances in other hydrosols.
