    An ethnobotanical study on the usage of wild plants from Tara Mountain (Western Serbia)

    No full text
    In this study an ethnobotanical survey was conducted in western Serbia (Mt. Tara) with the aim of collecting and preserving the traditional botanical knowledge. A group of local inhabitants (56) was interviewed using semi-structured questionnaires. The Relative Frequency of Citation (RFC) and Jaccard Index (JI) were calculated. There are 78 wild plant species recorded. The reported plant species belong to 34 families, where the families Rosaceae (41.18%), Asteraceae (23.53%) and Lamiaceae (20.59%) were dominant. Out of 78 documented plants, 70 plants (89.74%) are used in folk medicine, 42 (53.85%) in human nutrition, 22 (28.20%) in animal nutrition, 14 (17.95%) plants are used for miscellaneous purposes, while two plants (2.56%) are used in ethnoveterinary medicine. The highest RFC was recorded for Vaccinium myrtillus (0.38), followed by Urtica dioica (0.34), and Hypericum perforatum (0.25) and Fragaria vesca (0.25). The most frequently used mode of preparation was as an infusion (70.51%), while the most used plant part was the leaf (56.41%) followed by the flower/inflorescences (37.18%) and aboveground parts (28.21%). The highest degree of similarity was determined with studies conducted in close proximity (Mt. Zlatibor, JI 33.04). Local recipes and new usage of some well-known traditional plants in Serbia and the Balkans were documented.M230.924726248

    Unraveling the Phytochemical Profile Variability and Antioxidant Activities of Different Parts of Ammi visnaga (L) Collected from Taounate Region

    Ammi visnaga is a very popular medicinal plant well known for its biological properties afforded by its dense chemical composition highly dependent on environmental factors. The present study was designed to examine the antioxidant potencies using four complementary assays (Total phenolic content (TPC), total antioxidant capacity (TAC), dihydroxycinnamic acid derivative content (HCA), and cupric ion reducing antioxidant capacity (CUPRAC)) as well as the phenolic profile of different parts of Moroccan Ammi visnaga. The obtained results showed that the flower extract registered the highest amount of TPC (49,71 ± 0,12 mg GAE/g) and antioxidant activity TAC (62.07 ± 2.98 mg AAE/g). Concerning the phenolic profile, the most abundant individual phenolic compounds found in high amounts are chlorogenic acid (56.03%, 11.23% and 32.29 for stem, leaves and flowers, respectively), isorhamnetin_3-O-rutinoside (17.86%, 12.16% and 19.01% for stem, leaves and flowers, respectively), isorhamnetin_3-O-glucoside (15.96%, 10.69%, 10.37% for stem, leaves and flowers, respectively), quercetin_3-O-glucoside (1.61%, 21.11% and 2.85% for stem, leaves and flowers, respectively), kaempferol_3-O-glucoside (1.04%, 3.17% and 7.40% for stem, leaves and flowers, respectively) and isorhamnetin (0.57% 7.59% and 2.77% for stem, leaves and flowers, respectively). The outcomes of this study showed that different parts of A. visnaga contain several bioactive compounds with unique biological properties, so the data required further validation using experimental models.71777
