Abstract: Summary Background Chrysanthemum indicum, an oriental medicinal plant, has been shown to display a variety of pharmacological activities including antibacterial and anti-inflammatory effects. Aims In this study, we evaluated the ability of C. indicum extracts to inhibit in vitro tyrosinase activity and the skin care effects of cosmetic formulations containing 0.5% C. indicum water extract in human volunteers. Patients/Methods The formation of dopachrome from L-dopa by mushroom tyrosinase was observed after treatments with C. indicum extracts. The volunteers received placebo (no extract) or test (0.5% C. indicum water extract) cosmetic cream and applied it on their face three times a day for 6 weeks. Biophysical skin parameters were measured every 2 weeks. Results Chrysanthemum indicum methanol and water extracts dose dependently inhibited mushroom tyrosinase activity, and the effects of methanol extract were similar to those of kojic acid, a well-known tyrosinase inhibitor. Clinical evaluations revealed that application of cosmetic formulations containing C. indicum water extract time dependently reduced melanin levels over 6 weeks, whereas the placebo group showed no effect. No changes in moisture, elasticity, wrinkles, evenness, and pore size were observed in either group. HPLC-DAD-ESIMS analyses revealed that luteolin and acacetin-7-O-rutinoside are the major flavonoid compounds in C. indicum water extract. Conclusion These results suggest that C. indicum water extract could be applied as a natural skin-whitening agent for functional cosmetic uses, due to its melanin-reducing efficacy.

TL;DR: It is suggested that the tetraploid form of C. indicum may have expanded its range southward during recent Quaternary glacial periods when forests retreated in south China as conditions became drier.
Abstract: A detailed knowledge of the geographical distribution of cytotypes within and between species comprising a polyploid complex is critical to our understanding of the history and evolution of such complexes. In the present study we examined the geographical distributions of cytotypes within six tentatively delimited species comprising the Chrysanthemum indicum complex in China. We determined the ploidy of 188 individuals sampled from 47 populations, based on DNA content using flow cytometry. In addition, chromosome counts were made on samples of each taxon. We confirmed that all samples of C. rhombifolium and C. lavandulifolium were diploid (2n = 18), those of C. hypargyrum and C. potentilloides were tetraploid (2n = 36), and those of C. vestitum were hexaploid (2n = 54). In contrast, we confirmed that C. indicum contained both diploid and tetraploid cytotypes. We found that in addition to marked differences in genome size between ploidy levels, there was a variation in genome size between species of the same ploidy level. Although the diploid, tetraploid, and hexaploid taxa of the complex, as well as the diploid form of C. indicum, occurred only in central and northern China, the tetraploid form of C. indicum was widespread both north and south of the Yangtze River. We suggest that the tetraploid form of C. indicum may have expanded its range southward during recent Quaternary glacial periods when forests retreated in south China as conditions became drier.

TL;DR: The steam distilled oils both from flowers and leaves, as well as from total aerial parts of CHRYSANTHEMUM INDICUM L. (small-flowered form), were obtained and analyzed by GC and GC/MS.
Abstract: The steam distilled oils both from flowers and leaves, as well as from total aerial parts of CHRYSANTHEMUM INDICUM L. (small-flowered form), were obtained and analyzed by GC and GC/MS. Their main components are borneol, chrysanthenone and bornyl acetate.

TL;DR: Phylogenetic analyses declared that the chloroplast genome could distinguish C. indicum from its closely related species and might become a potential super barcode for the identification of these species.
Abstract: Chrysanthemum indicum, an important medicinal plant of Asteraceae, had a long history in use for medicine in China. In this study, the complete chloroplast genome of C. indicum was sequenced by a 454 sequencing platform, and the structure of the obtained chloroplast genome was also analyzed. The complete chloroplast genome of C. indicum was 150 972 bp in length and had a pair of inverted repeats (IR, 24 956 bp) separated by a large (LSC, 82 741 bp) and small single copy (SSC, 18 319 bp) regions. Its total GC content was 37.48%. There were 126 chloroplast genes including 83 protein-coding genes, 35 tRNAs and eight rRNAs were successfully annotated. Sixteen genes contained one or two introns. Phylogenetic analyses declared that the chloroplast genome could distinguish C. indicum from its closely related species and might become a potential super barcode for the identification of these species.

TL;DR: In this paper, the adsorption capability of raw and biochar forms of Chrysanthemum indicum flowers biomass to remove cobalt ions from aqueous solution in a fixed-bed column was investigated.
Abstract: The present study investigates the adsorption capability of raw and biochar forms of Chrysanthemum indicum flowers biomass to remove cobalt ions from aqueous solution in a fixed-bed column. Column adsorption experiments were conducted by varying the bed height (1.0, 2.0, 3.0 cm), flow rate (1.0, 2.5, 5.0 mL min−1) and initial cobalt ion concentration (25, 50, 75 mg L−1) to obtain the experimental breakthrough curves. The adsorption capacity of the raw and biochar forms of C. indicum flowers were found to be 14.84 and 28.34 mg g−1, respectively, for an initial ion concentration of 50 mg L−1 at 1.0 cm bed height and 1.0 mL min−1 flow rate for Co (II) ion adsorption. Adam–Bohart, Thomas and Yoon–Nelson models were applied to the experimental column data to analyze the column performance. The Thomas model was found to best represent the column data with the predicted and experimental uptake capacity values correlating well and with higher R 2 values for all the varying process parameters. Desorption studies revealed the suitability of the adsorbents for repeated use up to four adsorption–desorption cycles without significant loss in its efficiency. It can thus be inferred from the fixed-bed column studies that C. indicum flowers can suitably be used as an effective adsorbent for Co (II) ion removal from aqueous solution on a higher scale.
