TL;DR: The flowers of Chrysanthemum indicum, i.e. Ye-ju-hua, has been widely used in China as an important heat-clearing and detoxifying herb for the treatment of inflammation, headache, and vertigo, and a phytochemical investigation of this herb has led to the isolation of two new eudesmane sesquiterpenoids.
Abstract: The flowers of Chrysanthemum indicum, i.e. Ye-ju-hua recorded in the Chinese Pharmacopoeia, has been widely used in China as an important heat-clearing and detoxifying herb for the treatment of inflammation, headache, and vertigo. A phytochemical investigation of this herb has led to the isolation of two new eudesmane sesquiterpenoids, 7-epi-eudesm-4(15),11(13)-diene-1β,3β-diol (1) and 7-epi-1β-hydroxy-β-eudesmol (2). The molecular structures of these new sesquiterpenoids were established based on the comprehensive spectroscopic analyses, including NMR, MS, and IR, and comparing with the literatures.

TL;DR: Subordinate function value analysis showed that the salt-tolerance was in order of Chrysanthemum indicum var.maruyamanum, Ajania shiwogiku var.kinokuniense, Artemisia japonica,Artemisia vulgaris, and Chrysantheum indicums, being consistent with the results evaluated by the index of 50%-injured leaf area.
Abstract: Taking Ajania shiwogiku var.kinokuniense,Artemisia japonica,Artemisia vulgaris,and Chrysanthemum indicum var.maruyamanum as test plants,a hydroponic experiment was conducted to screen the appropriate concentration for salt-tolerance,and to compare the salt-tolerance of test plants.The culture medium Hogland solution was added with 0,75,100,150,250,and 400 mmol·L-1 of NaCl,and the changes of plant morphological characteristics were observed.The results showed that 100 and 150 mmol·L-1 of NaCl were the appropriate concentrations for testing salt-tolerance.Obvious injury symptoms appeared at 10 days and 6 days under 100 and 150 mmol·L-1 of NaCl stress,respectively.The salt-tolerance of the four species was evaluated in terms of root vigor,malondialdehyde and chlorophyll contents,and morphological changes under 120 mmol·L-1 of NaCl.Subordinate function value analysis showed that the salt-tolerance was in order of Chrysanthemum indicum var.maruyamanumAjania shiwogiku var.kinokunienseArtemisia vulgarisArtemisia japonica,being consistent with the results evaluated by the index of 50%-injured leaf area.

TL;DR: A new sesquiterpene compound, named chrysanthetriol was isolated from the more polar fraction of the title plant, and the molecular formula was showed to be C15H26O3.
Abstract: Chrysanthemum indicum L. is a Chinese traditional drug used for antifebrile, detoxication and hypotensive purposes. In continuation of our efforts to search for the active principles of this species, a new sesquiterpene compound, named chrysanthetriol was isolated from the more polar fraction of the title plant. Chrysanthetriol is a colorless oil, [alpha]D20-31.8 degrees (c 0.3, MeOH). HRMS showed the molecular formula to be C15H26O3. The structure and stereochemistry of chrysanthtriol was elucidated as I by the use of 1H-1H COSY, 1H-13C COSY, 1H-13C COLOC 2D NMR spectroscopy.

TL;DR: The physicochemical characteristics of sugar-snap cookies made with various levels (0, 1.5, 3, 4.5 and 6% w/w) of Chrysanthemum indicum Linne powder were investigated in this article.
Abstract: This study investigated the physicochemical characteristics of sugar-snap cookies made with various levels(0, 1.5, 3, 4.5, and 6% w/w) of Chrysanthemum indicum Linne powder. Dough pieces were baked for 11 min at 180℃ in an electrically heated rotary oven. All items were measured after cooling for 1 hour at room temperature. The results were as follows. Dough pH was significantly decreased in the 3%, 4.5% and 6% samples in contrast to the control sample(p<0.001). Furthermore, lightness (L*-value) and spread factor decreased significantly according to increasing Chrysanthemum indicum Linne powder concentration(p<0.001). However, dough density was significantly increased in the 3%, 4.5%, and 6% samples in contrast to the control sample(p<0.001). Likewise, the hardness and redness(a*-value) of the cookies increased significantly with increasing Chrysanthemum indicum Linne powder concentration(p<0.001). However, the moisture content of the dough was not significantly affected by the Chrysanthemum indicum Linne powder concentration. Finally, the powder concentration had positive correlations with dough density(p<0.01) and hardness(p<0.01). However, it had negative correlations with dough pH(p<0.01), lightness(L*-value)(p<0.05), and spread factor(p<0.01). Overall, the results showed that there were significant correlations between Chrysanthemum indicum Linne powder concentration and the physicochemical characteristics of the cookies.

TL;DR: In this article, the use of chemical mutagens such as ethyl methanesulfonate (EMS) to induce morphological mutants in C. indicum var. aromaticum using EMS treatments with different doses, and analyze the morphological and physiological traits of obtained mutants in expectation of finding favorable mutants.
Abstract: Mutation breeding is considered to be economic and efficient in plant improvement, and the use of chemical mutagens such as ethyl methanesulfonate (EMS) can potentially address plant breeding challenges. The aim of this study was to induce morphological mutants in C. indicum var. aromaticum using EMS treatments with different doses, and to analyze the morphological and physiological traits of obtained mutants in expectation of finding favorable mutants. Results revealed significant effects of EMS doses on seed germination. The sample germination rate significantly decreased with increasing of EMS doses. The obtained morphological mutants were two viable types, containing leaf and stem mutants. Overall leaf size was significantly larger as a result of EMS treatments. And the height of mutant plants was significantly higher. Anatomical characteristics exhibited changes in both leaves and stems of the mutant plants. The puncture strength of the bent stem from the mutant plants was low, with weak penetration resistance. The total lignin and cellulose contents of mutant plants stem decreased significantly as a result of the EMS treatments. These results demonstrate the efficiency of EMS to induce mutations in C. indicum var. aromaticum, and this method can be useful in the future to assist breeding of this plant.
