“…Preparation of a standard ursolic acid solution standard curve: A concentration series is created by dissolving 10 mg of standard ursolic acid in 50 mL of sulfuric acid. The absorbance of each solution was measured with a wavelength of 310 nm to create a standard curve (Murav'ev et al 1972). The linear regression line equation, generally formulated as y = bx + a, is searched using the standard solution content data as the x-axis and the absorbance value as the y-axis.…”

Abstract. Anam K, Mudyantini, Rakhmawati R. 2017. Growth and ursolic acid content of pearl grass (Hedyotis corymbosa) on variations in water availability. Cell Biol Dev 1: 55-62. The purpose of this study is to determine how different water sources affect the growth and levels of ursolic acid in pearl grass (Hedyotis corymbosa (L.) Lam.). A factorial, completely randomized design (CRD) with a single factor of five replications each was used for the experiment. Water stress conditions were created by providing different levels of water availability in the growing media, namely 40, 60, 80, and 100% field capacity (control). The plants were given the treatment for 8 weeks. Plant growth, including the number of leaves, fresh and dry weight, and plant ursolic acid content, were all measured in this study. The data were analyzed using analysis of variance (ANOVA), and the DMRT test at the 5% test level was used to determine the significant difference between treatments. The results showed that the water availability treatment significantly affected the number of leaves, fresh weight, and dry weight, but it did not affect the ursolic acid content in plants. The treatment with the lowest water availability (40% KL) produced low yields on growth parameters and ursolic acid levels. Ursolic acid levels were lowest under drought stress conditions (40% KL), while they were highest under excess water conditions (100% KL).

“…Flavonoids, tannins, anthocyanins, and water-soluble polysaccharides were determined according to the State Pharmacopoeia (RSP-XI); ascorbic acid was determined by a photocolorimetric technique [6]; cartotenoids and triterpene saponins were determined as described in [7,8], respectively; coumarins were determined by a spectrophotometric technique [9]; glycyrrhizic acid was determined by a combined gas chromatography -mass spectrometry (GC/MS) method as described in [10]; and flavonoids (rutin, hyperoside), by an analogous technique described in [11,12].…”

Immunomodulating effect of the antiulcerous drug ventrofit

et al. 2006

A new complex antiulcerogenic plant extract, ventrofit, has been created. The quantitative content of the main groups of water-soluble (flavonoids, polysaccharides, vitamin C, anthocyanins, tannins) and lipophilic (triterpene saponins, coumarins, carotenoids) biologically active substances in the new preparation has been determined. The immunomodulating activity of ventrofit with respect to immunodepression induced by azathioprine has been established in experiments on CBA and F1 (CBA´C57Bl/6) mice. The extract increased the characteristics of cellular, humoral, and macrophage chains of the immune response. 501 0091-150X/06/4009-0501
