“…anthocyanins were determined in the petioles of twenty-nine rhubarb (Rheum spp.) varieties In result identified that antioxidant activity ranged from 463±50 (Rheum officinale) to 1242±2 μmol Trolox/g, the phenolic content varied from 673±41 (Loher Blut) to 4173±23 mg GAE/100 g. The percentages of two main anthocyanins in rhubarb, cyanidin 3-glucoside and cyanidin 3-rutinoside varied from 66.07:33.93, respectively, in Valentine to 9.36:90.64, respectively in R. officinale (Takeoka et al, 2013).…”

A B S T R A C TThis work was performed to comparison antioxidant activity of Rheum ribes fruit and seed methanolic extracts against to protein oxidation. Consequently determined that antioxidant capacity with cupric of method, respectively in fruit extract to be 2.44±0.212, in seed to be extract 5.30±0.245 mmol gG 1 , antioxidant radical scavenging with ABTS* method in fruit extract to be 11-78%, in seed extract 2-15% levels. The OH · power reduction for the Rheum ribes fruit extract 34-49, 22±0.04%, while seed extract to be 49-80±0.04%, H 2 O 2 removal activity for fruit extract was at 30.31-57.87%, while seed extract was at %33.33-54.57 levels. Also were determined the total phenolic content, respectively in fruit extract to be 2.312±0.0007 in seed extract to be 3.298±0.0007 mg of GA equivalent/g, total flavonoid content in fruit extract to be 2.79±0.0066, in seed extract to be 7.31± mg 0.1787 of Q equivalent/g, total anthocyanin content, respectively in fruit extract to be 0.5 mg of cyanidin-3-glucoside equivalent/L, in seed extract to be 1.26 mg of cyanidin-3-glucoside equivalent/L. were found. Protein oxidation in fruit was 40.64-56.5%, in seed extract it was 37.98-51.46% were determined. Anti-lipid peroxidation inhibition % in fruit extract to be 13.72-27.4%, in seed extract to be 8.459-27.09% was determined.

“…TNF-α plays important roles in the development of intractable stomatitis such as RAS and OLP [15,16] . Artemisia capillaris flower, gardenia fruit, and rhubarb have antioxidant activity [14,[17][18][19][20][21] . In particular, gardenia fruit induces the expression of NF-E2 related factor 2 (Nrf2) mRNA, which is followed by an upregulation of antioxidant response element (ARE)-mediated genes such as heme oxygenase-1 (HO-1) [22][23][24][25] .…”

Intractable stomatitis is a chronic inflammatory disease of oral mucosa, with unclear etiopathogenesis. Kampo Medicines (KMs), i.e., Japanese herbal medicines, effectively treat stomatitis. The precise effects of KMs on intractable stomatitis are not established. We present the details of several patients with intractable stomatitis who were well-treated with KMs (i.e., Inchinkoto, Orento, Goreisan, and Byakkokaninjinto). We also review the literature on the link between intractable stomatitis and KMs. KM-related anti-inflammatory and antioxidant activity may suppress intractable stomatitis. KMs may also facilitate wound healing through increased saliva secretion. KMs may therefore be useful for the treatment of intractable stomatitis.

“…They are a natural dye of plant origin and have a lot of health-promoting properties, among other things: they protect tissue against excessive UV radiation (Gawałek et al 2017). Nowadays they are more and more often used in pharmaceutical and cosmetic industry (Takeoka et al 2013). The presence of anthocyanin compounds in rhubarb is used for effective treatment of cancer cells by its antioxidant effect.…”

Application of artificial neural network for the quality-based classification of spray-dried rhubarb juice powders

The aim of the study was to develop a neural model enabling classification of fruit spray dried powders, on the basis of graphic data acquired from a bitmap received in the process of spray drying. The neural model was developed with multi-layer perceptron topology. Input variables were expressed in 46 image descriptors based on RGB, YCbCr, HSV (B) and HSL models. Sensitivity analysis of input variables and principal component analysis determined the significance level of each attribute. The optimal model with the lowest error value root mean square, at the level of 0.04 contained 46 neurons in the input layer, 11 neurons in the hidden layer, 10 neurons in the output layer. The results allowed to show that dyeing force (color features) had influence on effective differentiation of the research material consisting of spray-dried powders of rhubarb juice with various dried juice content levels: 30, 40 and 50% as well as high (“H”) and low (“L”) level of saccharification a chosen carrier (potato maltodextrin).
