“…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.

“…It is listed in current editions of the European Pharmacopoeia, US Pharmacopeia and other official papers (Damianova, Tasheva, Stoyanova & Damianov, 2008;Gavarić et al, 2015), exhibiting carminative, antispasmodic, antitussive, expectorant, bactericidal, antihelmintic and astringent effects. Traditionally, the herb has been used for the treatment of dyspepsia, chronic gastritis and diseases of the upper respiratory tract (Fecka & Turek, 2008;Helmy, Farrag & Hasaballah, 2015).…”

The genus Thymus encompasses a wide array of taxa, many of which remain underexplored in terms of their phytochemical profile. In this study, we investigated the phytochemical composition of volatile compounds of five Thymus species native to Greece using gas chromatography combined with mass spectrometry. Two samples of T. parnassicus collected from Mts Parnitha and Parnassos were studied. The predominant compounds in the Parnitha sample were α-cadinol (13.53%), E-caryophyllene (11.83%) and selin-11-en-4α-ol (7.29%). The sample from Mt. Parnassos exhibited a high concentration of E-caryophyllene (35.20%) followed by β-bisabolene (10.41%). Additionally, two species, namely T. leucotrichus subsp. leucotrichus and T. atticus, were collected on Mt. Chelmos (Peloponnese). The essential oil of T. leucotrichus was rich in elemol (35.56%), α-eudesmol (11.15%) and β-eudesmol (6.11%). Thymus atticus exhibited a high concentration in linalool (63.04%) and p-cymene (25.63%). In addition, two samples of T. holosericeus collected from Kefalonia Ιsland were both rich in geraniol (89.9% and 87.7%, respectively). We also examined the volatile profile of T. laconicus, a local endemic species of SE Peloponnese (Lakonia area), which remains unexplored. Carvacrol (32.7%) and p-cymene (29.7%) were identified as the dominant compounds. Our study contributes valuable insights into the chemical profile of Thymus spp. and sheds further light on the well-known chemical polymorphism within this genus.
