“…perfoliata had the highest phenol and flavonoid content thus, showing the highest antioxidant activity which is in agreement with previous findings [5]. The TPC values of S. scardica infusions were similar to previous reports [21] and lower than others [34], while regarding TFC values S. scardica from Mt. Menoikio was similar to previous reports [21] but from Pieria, Mt.…”

“…However, some TMS-derivatives of the phenolic acids where not detected with HPLC; this difference can be attributed to the different sensitivity of each method as well as to the different pre-treatment of the sample. Among S. scardica samples, caffeic and ferulic acid were comparable to previous reports while vanillic acid was much higher [21]. Regarding transcinnamic acid, Ss_P and Ss_V had comparable values to Irakli et al while p-coumaric values were much lower [21].…”

“…Despite the medicinal applications of Sideritis spp. and the consumers interest, limited studies have been conducted on the evaluation of the drinking tea [21] and correlation of its phytochemical composition with its bioactivity [14][15][16]. Since tea is amongst the most popular beverages, having custom made blends with specialized medicinal properties will benefit certain vulnerable consumers groups.…”

Plant species of the Sideritis genus are native to the Mediterranean region and widely used through millennia for their medicinal and culinary properties. They are mostly known as mountain tea or Shepard tea and in the last few years, they are on the spotlight due to the production of an enormous variety of bioactive secondary metabolites exerting a wide range of pharmaceutical applications. In the present study the biochemical value and the health promoting components of various indigenous Sideritis species was assessed: S. perforiata subsp. perfoliata, S. perfoliata subsp. athoa, S. syriaca, S. raeseri, S. scardica. A thorough biochemical analysis was conducted, including total phenols and flavonoid content, antioxidant activity, amino acids, elemental and polar/non polar metabolite profiling. S. perfoliata subsp. perfoliata had the most diverse and rich terpene profile among the studied species, while its infusion had the highest phenol and flavonoid content thus, showed the highest antioxidant activity. The diverse chemotype of Sideritis species can be used as a guide on the preparation of tea mixes with the desired metabolite content targeting specialized medical applications or may assist on the design of breeding strategies.

“…for treating gastrointestinal disorders, sore throats, asthma, bronchitis, the common cold, etc. The reported bioactivities of hydro-alcoholic and other extracts-i.e., anti-inflammatory, neuroprotective, analgesic, antioxidant, antimicrobial, as well as its gastrointestinal protection properties-are attributed to a variety of secondary metabolites of S. scardica belonging to terpenes, di-and triterpenes, phenylpropanoids, and polymethoxylated flavones [3][4][5][6][7][8].…”

Sideritis scardica (S. scardica) is an endemic medicinal species of the Central Balkan Peninsula. The aerial parts are traditionally used in folk medicine and, therefore, have been collected extensively from natural habitats. Overexploitation in combination with climate change has resulted in severely fragmented populations. In this context, the purpose of this study was to access the abundance and phenotypic diversity of S. scardica populations in relation to plant community structure and environmental and anthropogenic factors in six mountainous areas of Northern Greece. For this reason, the floristic composition and diversity was determined by accessing the number of plant species, number of individuals per plant species, and plant cover in each study area. In addition, the soil properties of the studied areas were determined and the phenotypic diversity of S. scardica populations was accessed through the imaging of leaf and inflorescence main characteristics. As a result, 141 plant species were identified in all studied areas, while the floristic composition clearly distinguished the North-Central from the North-Eastern studied areas. S. scardica was the predominant species in the habitats where the presence of forbs was favored, while a high presence of graminoid and shrub species in the study areas depressed its presence. A high coefficient of variations was recorded among the six populations, varying from 12.2%–29.2% and 13.3%–43.1% for inflorescence and leaf traits.

In this study, optimization of the extraction of phenol compounds from Mentha piperita using ultrasonic waves with response surface methodology (RSM) was assessed. In this regard, a central composite design with three independent variables of time (5, 27.5, and 50 min), temperature (25, 45, and 65°C), and concentrations of ethanol in the water–ethanol solution (0%, 50%, and 100%) was used. Besides, the antioxidant activity tests (DPPH radical scavenging assay, ferric reducing antioxidant power [FRAP], and oxidative stability indexes [OSI]) were examined. Significant effects of independent variables on the extraction of phenol compound, DPPH radical scavenging power, and OSI of M. piperita extract, with the regression coefficients of 0.89, 0.92, and 0.94, respectively, were noted. However, no significant difference in terms of the FRAP among different treatments was noted. Also, the best antioxidant activity of M . piperita was obtained by using the ultrasonic wave for 50 min at 65°C and 59.6% v/v ethanol/water solution. While the findings of RSM confirmed the experimental results, due to the favored properties of M . piperita extract by the proposed method, further research to investigate possible applications in the food industry is recommended.
