Anatomical and Phytochemical Characteristics of Different Parts of L. Extracts, Essential Oils, and Their Antimicrobial Potential.

(Hypericaceae) is a genus that comprises a high number of species around the world. In this study, the roots, aerial parts, flowers, fruits, and aerial parts with flowers from were macerated separately by methanol and water and then fractionated by different solvents of, such as ethyl acetate, -hexane, butanol, dichloromethane, aqueous residue sub-extracts, and ethnobotanical use. All the extracts, sub-extracts and essential oils of were investigated for the first time in detail for their antimicrobial, total phenolics, and antioxidant activities. Anatomical structures of the root, stem, leaf, upper and lower leaf surface, stamen, sepal, and petal of were examined. The biochemical layout of essential oils was determined by GC and GC/MS. The antioxidant activity was determined by free radical scavenging activity (by DPPH). Antimicrobial activity was applied against ATCC 10231, ATCC 8739, ATCC 6538, ATCC 19659, and ATCC 750 using microdilution methods. The essentials of the aerial parts, flower, and fruit are characterized by the presence of monoterpene hydrocarbons, whereas roots oil include alkanes. The GC-FID and GC-MS analysis showed that major components of roots, aerial parts, flowers, and fruits oils were undecane (66.1%); α-pinene (17.5%), γ-terpinene (17.4%), and α-thujene (16.9%); α-pinene (55.6%), α-thujene (10.9%), and γ-terpinene (7.7%); α-pinene (85.2%), respectively. The aerial part sub-extracts indicated a greater level of total phenolics and antioxidant potential. The -hexane sub-extracts (from aerial part, flower, and aerial part with flower) showed the best activity against , with 39.06 µg/mL MIC value. The presented research work indicates that can be a novel promising resource of natural antioxidant and antimicrobial compounds.
