“…Among them only Cinnamomum zeylanicum is grown commercially. Recently, two accessions of Cinnamomum zeylanicum named as ''Sri Wijaya'' and ''Sri Gemunu'' have been developed for commercial cultivation with improved chemical profiles and yields (Azad et al, 2015). Yet, scientific evidence on biological activities and the anti-diabetic properties of these novel Cinnamon varieties have not been explored.…”

Background Diabetes mellitus type 2 (DMT2) is a leading metabolic disorder in the world. Anti-diabetic actions of phytochemicals from various medicinal herbs have been explored as an alternative therapy in the management of DMT2 due to adverse effects of synthetic drugs used in allopathic medicine. α-amylase and α-glucosidase inhibitory potential and phytochemical profiling were investigated in aqueous extracts of two new Cinnamomum zeylanicum accessions, namely C. zeylanicum Sri Wijaya (SW), C. zeylanicum Sri Gemunu (SG) and commercially available C. zeylanicum (CC). Methods Microwave Digestion (MD), Pressurized Water Extraction (PWE), Steam Distillation (SD), Solvent Extraction (SE), Decoction Water Extraction (DWE) and Infusion Water Extraction (IWE) methods were used to prepare Cinnamon quill extracts. Total phenolic content (TPC, Folin-Ciocalteu method) and Proanthocyanidin content (PC, vanillin assay), α-amylase and α-glucosidase inhibition of Cinnamon extracts were determined spectrophotometrically. The α-amylase and α-glucosidase inhibition were reported in terms of IC50 value. The phytochemical profiling was accomplished by GC-MS technique. Results and Discussion Lowest IC50 values were observed in PWE and DWE of SW. The highest PC and TPC were also observed in PWE and DWE of SW. Pressured water and decoctions are promising methods for the extraction of antidiabetic constituents from cinnamon. Benzoic acid, cinnamyl alcohol, benzyl alcohol, and 4-Allyl-2,6-dimethoxyphenol were identified as major compounds in SW extracts. These compounds are believed to be responsible for strong enzyme inhibitory activity of the extracts. Conclusions This is the first study to explore the use of pressured and decoctions water to extract anti-diabetic phytochemicals from cinnamon. The extensive metabolite profiling of novel SW and SG extracts and comparison of that with commercially available CC are reported for the first time in this study. The C. zeylanicum, SW accession holds some promise in the management of diabetes.

“…Those contrasts with the results of mass selection stage I of E. purpurea cultivated in the highlands of Central Java, Indonesia, where E. purpurea accession BHU5 has no variation (Subositi and Fauzi 2016). Morphological variations can occur as a result of both internal factors, such as cross-pollination (Azad et al 2015;Liyanage et al 2021) and external factors, such as differences in cultivation altitude and planting season (Kofidis et al 2007). This one variation, however, is consistent with the findings of Subositi and Widiastuti (2013), who discovered that E. purpurea accession 3 has uniform tiller characteristics and only slightly different morphological characters.…”

Abstract. Cahyaningsih AP, Etikawati N, Yunus A. 2022. Morphological characters variation of Indonesian accession Echinacea purpurea in response to gamma-ray irradiation. Biodiversitas 23: 5351-5359. Indonesia was one of the countries that introduced E. purpurea as a medicinal plant. Accessions of E. purpurea that have been successfully cultivated in Indonesia have narrow genetic diversity, lack accession variation, and have almost uniform tillers. This study was conducted to determine the effect of different doses of gamma-ray irradiation on morphological characteristics of E. purpurea accession B2P2TOOT. The experimental design was a Randomized Block Design with three replications, and six doses of gamma-ray irradiation (0, 15 Gy, 20 Gy, 25 Gy, 40 Gy, and 60 Gy) were used. The qualitative morphological data were presented descriptively; quantitative data were analyzed using ANOVA followed by a DMRT test at a 5% level with SPSS 16.0 application. The Dice similarity algorithm analyzed the similarity index, group analysis, and dendrogram construction using the UPGMA method with the NTSYS 2.02 application. Gamma-ray irradiation treatment increased the survival rate of E. purpurea plants grown in tropical lowlands. A dose of 15-60 Gy gamma irradiation did not affect the qualitative morphology of E. purpurea roots, stems, and leaves. Irradiation at doses of 40 Gy and 60 Gy resulted in flowers with more variation in color, overall flower shape, and arrangement of ray floret. Gamma irradiation significantly affected plant height, leaf length, leaf area, flower angle, and the first day of flowering. The 40 and 60 Gy doses resulted in longer leaves with wider leaf surfaces. The dendrogram revealed that E. purpurea irradiation resulted in two main groups, with doses of 40 and 60 Gy forming their groups and increasing morphological variation by 30% compared to controls.

“…Sri Lankan cinnamon accessions exhibit a wide variation in morphology including leaf and flower characters, which may reflect the genetic diversity (Azad et al, 2016;2018). Leaf morphology of cinnamon has been suggested as a morphological marker for essential oil composition (Wijesinghe & Gunarathna, 2001) and for genetic analysis (Azad et al, 2015). The correlation between leaf morphology and disease severity was tested during this study, which would be useful in the identification of resistant genotypes for breeding programmes.…”

Leaf spot and rough bark diseases are of high concern among cinnamon growers in Sri Lanka due to potential yield losses. Comprehensive information on distribution and intensity of the above diseases is not available in Sri Lanka. During this study, disease assessment keys were developed for leaf spot and rough bark diseases with subjective scales, which could be useful in assessing the severity of the two diseases. Two hundred and eighty cinnamon accessions from major cinnamon growing areas of Matara, Galle, Kalutara, Kurunegala, Ratnapura and Humbantota Districts were used to determine the intensities of the above diseases. All the districts showed a high level of leaf spot disease severity, where 23.81 % accessions from Galle and 17.14 % accessions from Kalutara districts exhibited the leaf spot disease severity scale of 6. Moreover, 60 % accessions from Kurunegala and 45.71 % accessions from Kalutara districts showed the leaf spot disease severity scale of 5. According to the study on rough bark disease severity, none of the major cinnamon growing areas is at a high risk of rough bark disease. However, the present study indicates the initiation and progression of rough bark disease in the six districts, where Matara district showed considerable levels of infection having 17.39 %, 11.59 %, 5.80 % and 4.35 % of accessions with disease severity scales 2, 3, 4 and 5, respectively. The estimates of the two disease severities explain the present scenario of extent of the two diseases across major cinnamon growing areas in the country.
