Abstract

Lycium barbarum L. (Solanaceae), grown as a naturalized species in Turkey, is known by its Turkish name "atlangaç, yemişgen". The red-colored fruits of the species are known as Fructus Lycii (Gouqizi, goji berry) and have a history of 2000 years. L. barbarum fruits contain high vitamin C, B, and E vitamins, polysaccharides, phenolic acids, flavonoids, carotenoids (0.03-0.5%), sterols, amino acids, essential oil, and trace amounts of alkaloids. Atropine and scopolamine alkaloids have been detected in root bark. L. barbarum has been studied for its anticancer, antioxidant, antiaging-related macular degeneration, hypoglycemic, immunomodulator, antihypertension, lipotropic liver protective, antiaging, and antioxidant effects. There are reported various bioactivities of its fruits such as emmenagogue, diuretic, antipyretic, tonic, male fertility enhancer, and hepatoprotective. It has been stated that root bark (Cortex Lycii radicis) is used especially in night sweats and chronic low fever, diabetes, and hypertension. Lycium barbarum is an ethnobotanically valuable species due to its curative effects. However, anatomical studies have been carried out on root and stem secondary xylem anatomy, leaf anatomy, leaf anatomy of different cultivars, and fruit anatomy and are limited in number. To determine the anatomical features of this naturalized species, root, stem, and leaf anatomies were examined by light microscopy. Cross-sections of roots and stems taken by hand were treated with chloralhydrate and phloroglucin + 25% HCl, and the presence of alkaloids had demonstrated with Dragendorff reagent. Saftanin-fast green, a double staining method, was also applied to the sections. The mentioned sections have been examined under the light microscope, sections photographs have been taken, and the anatomical features of the tissues have been determined. It is the first study conducted with the species in the specified scope.
