TL;DR: The results showed that the absence of atractylenolide-II in the rhizome made the plant susceptible to S. rolfsii, and a significant inhibitory effect on mycelial growth was shown on in vitro antifungal studies.
Abstract: Atractylenolides compounds (atractylenolide-I, atractylenolide-II and atractylenolide-III) extracted from Atractylenolides macrocephala were analysed for their differential presence in the rhizome of both the infected and healthy plants and its fungitoxicity on prophylactic treatment with polysaccharides of Chrysanthemum indicum against Sclerotium rolfsii. It was evident that the plant under stress by pathogen has instigated the significant synthesis and accumulation of atractylenolide-II and atractylenolide-III in the rhizome of plants as a result of elicitation with polysaccharides of C. indicum. Our results also showed that the absence of atractylenolide-II in the rhizome made the plant susceptible to S. rolfsii. Furthermore, on in vitro antifungal studies, exogenous application of atractylenolide-II with the concentration of 200 μg/ml showed a significant inhibitory effect on mycelial growth by achieving a 77.23% antifungal activity rate, and a minimal inhibitory effect at a concentration of 12.5 μg/ml with atractylenolide-II. To our knowledge, this novel study on phytoalexins in A. macrocephala suggested that A. macrocephala plants produce elevated levels of atractylenolide-II and atractylenolide-III in a pattern typical of phytoalexins, in response to an eliciting treatment after infection.

TL;DR: Infected leaf samples of an ornamental plant Chrysanthemum indicum showing yellowing of leaf veins were collected from gardens of New Delhi (India) and an expected PCR product of size ~500 bp was amplified from total DNA extracts of symptomatic leaf samples with universal primers on the gene of coat protein region of begomovirus DNA-A component.
Abstract: Infected leaf samples of an ornamental plant Chrysanthemum indicum showing yellowing of leaf veins were collected from gardens of New Delhi (India). An expected PCR product of size ~500 bp was amplified from total DNA extracts of symptomatic leaf samples with universal primers on the gene of coat protein region of begomovirus DNA-A component. The presence of begomoviruses was also confirmed by Southern blot analysis using control cloned DNA-A probe of Cotton leaf curl virus. Sequence analysis of the virus infecting Chrysanthemum indicum showed 99% nucleotide sequence identity with Clerodendron yellow mosaic virus (EF408037).

TL;DR: In this article, the authors examined the dyeability, light fastness, washing fastness and the antibacterial activity of chitosan and nano silver composite non-woven fabrics dyed with an extracted solution from Chrysanthemum Indicum Linn.
Abstract: This study examines the dyeability, light fastness, washing fastness, and the antibacterial activity of chitosan and nano silver composite non-woven fabrics dyed with an extracted solution from Chrysanthemum Indicum Linn. The results show that an increase in the chitosan and nano silver percentage resulted in an increase in the values and values; however, the values decreased in the undyed condition. values of chitosan and nano silver composite non-woven fabrics were higher than cotton 100% non-woven fabrics in the dyed condition with an extracted solution from Chrysanthemum Indicum Linn, and mordant treatments influenced the chrominance change. In the dyed condition with an extracted solution from Chrysanthemum Indicum Linn, an increase in the percentage of chitosan and nano silver resulted in an increase of the K/S values. The dyeability of chitosan and nano silver composite non-woven fabrics increased by mordant treatments. The light fastness and washing fastness of the mordanted non-woven fabrics were better than the non-mordanted. For the antibacterial activity, the bacterial reduction rate of chitosan and nano silver composite non-woven fabrics was 99.9% to Staphylococcus aureus and Klebsiella pneumoniae.

TL;DR: Results indicate that the enhancement of osteoblast function by CIE may prevent osteoporosis and inflammatory bone diseases.
Abstract: Chrysanthemum indicum L. (Asteraceae) is a traditional herbal medicine that has been used for the treatment of inflammation, hypertension, and respiratory diseases due to its strong antagonistic activity against inflammatory cytokines. The effects of Chrysanthemum indicum L. Extract (CIE) for increasing cell growth, alkaline phosphatase (ALP) activity, and collagen content were totally inhibited, suggesting that the effect of CIE might be partly involved with estrogen activity. Furthermore, the protective effects of CIE on the response of osteoblasts to oxidative stress were evaluated. Osteoblastic MC3T3-E1 cells were incubated with hydrogen peroxide and/or CIE, and markers of osteoblast function and oxidative damage were examined. CIE significantly increased cell survival, ALP activity, and calcium deposition, and decreased the production of Reactive Oxygen Species (ROS) and Tumor Necrosis Factor- (TNF-) in osteoblasts. Taken together, these results indicate that the enhancement of osteoblast function by CIE may prevent osteoporosis and inflammatory bone diseases.
