STUDY ON ANATOMICAL FEATURES OF ROOTS, STEMS, LEAVES, CHEMICAL COMPOSITION AND ANTIFUNGAL, ANTIBACTERIAL ACTIVITIES OF CINNAMON OIL (Cinnamomum cassia (L.) J. PRESL) PLANTED IN THANH HOA

Tóm tắt

The paper presents anatomical features of roots, stems and leaves of cinnamon planted in Thanh Hoa. Anatomical features of the root and stem include epidermis, cortex, phloem, xylem and pith. Petiole and midrib have the epidermis, phloem, xylem, pith and thick tissue, blade composed of the upper epidermis, lower epidermis, palisade mesophyll and spongy mesophyll. The research identified 20 chemical components of cinnamon oil, in which the major constituents includes cinnamaldehyde (76.96 %), cinnamyl acetate  (11.07 %), coumarin (5.06 %). In the sample concentration of cinnamon oil samples exhibiting activity against 03 strains of E coli, P. aeruginosa, B. subtilis (with MIC value from 100- 200 μl/mL) with a sterile ring diameter of 10.22 mm; 16.27 mm; 14.61 mm and 01 strain of C. albicans (MIC = 50 µl/mL) with a sterile ring diameter of 24.45 mm.
