On Cinnamon) is often a normally located medicinal plant in Sri Lanka with confirmed antioxidant activity. It belongs to the loved ones Lauraceae and has been reported to possess lots of helpful activities such as becoming an antioxidant, antimicrobial, anticancer, anti-inflammatory, antidiabetic, antimutagenic and as an anti-tyrosinase agent (Rao and Gan, 2014). It was previously reported that the bark extract of Ceylon cinnamon has various antioxidant compounds, which can properly counteract with reactive oxygen species (ROS) for example hydroxyl radicals, superoxide anions at the same time as other free radicals. Lots of in vitro research reported the antioxidant effect of Cinnamomum zeylanicum Blume within the recent previous (Rao and Gan, 2014; Ghosh et al., 2015; Ranasinghe and Galappaththy, 2016; Premakumara and Abeysekera, 2020). The important oils obtained from the bark of Cinnamomum zeylanicum Blume and eugenol have shown extremely highly effective antioxidant activities (Chericoni et al., 2005) and in vitro studies revealed that Cinnamomum bark extracts effectively scavenged 2,diphenyl-1-picrylhydrazyl (DPPH) radicals and 2,20 -azino-bis(3-et hylbenzothiazoline-6-sulfonic acid) (ABTS) radical cations (Ranasinghe et al., 2013). Though it has already been established that Cinnamomum zeylanicum Blume features a important antioxidant activity, impact of its bark extract has in no way been investigated against doxorubicin induced cardiotoxicity in an animal model. Hence, the objective of this study was to investigate the ameliorative effects of Cinnamomum zeylanicum Blume bark against doxorubicin induced cardiac injury by the attenuation of oxidative pressure and structural cardiomyocyte adjustments in rats. 2. Material and procedures two.1. Collection of Cinnamomum zeylanicum Blume bark The cultivated Cinnamomum zeylanicum Blume bark was collected and identified in accordance with the descriptions offered by Jayaweera (1982). The species identification was confirmed by the curator from the National Herbarium, Royal Botanical Gardens, Peradeniya, Sri Lanka. A voucher specimen (2015/PG/VS/02) was deposited at the Division of Biochemistry, Faculty of Medicine, University of Ruhuna, Sri Lanka. two.2. Standardization of plant material 2.2.1. Physicochemical analysis The bark parts (cut into smaller pieces) of Cinnamomum had been dried at 40 until a continuous weight was reached and finely grounded. The powdered plant material was taken for the physicochemical evaluation. Tests for moisture content material, extractable matter and heavy metal analysis had been followed according to the WHO standards (1996). Microscopic analysis from the plant was carried out based on the WHO (2011) recommendations on quality control and standardization of plant materials. 2.2.two. Phytochemical analysis Phytochemical screening of Cinnamomum zeylanicum bark was followed to determine medicinally active substances located in the plant. Plant material was dried at 40 for three days, ground coarsely, and extracted in distilled water or organic solvents according to the strategy applied. The relevant extracts have been subjected to qualitative phytochemical screening assays for the RSK3 medchemexpress detection of anthracene HDAC6 web glycosides, cyanogenic glycosides, cardenoloid glycosides, saponins, polyphenols, alkaloids, flavonoids, tannins, minimizing sugars and proteins (Trease and Evans, 2009; Mushtaq et al., 2014; Yusuf et al., 2014). two.two.3. Total polyphenol content material and in vitro antioxidant activity of aqueous bark extract of Cinnamomum zeylanicum (ABEC) Constant weight in the Cinnamomum zeylanicum ba.
