TL;DR: In this paper, the ethanol extract of Chrysanthemum indicum Linne flowers was analyzed and found to markedly decrease AChE activity, with the presence of methoxy groups at C-4' in the B ring and a sugar at O-7 in ring A appear to be essential for the inhibition of ACHE.
Abstract: There is significant interest in finding new sources of acetylcholinesterase (AChE) inhibitors for use in treating Alzheimer's disease, since only a few AChE inhibitors are available for clinical use, such as galanthamine, physostigmine, and tacrine. The ethanol extract of Chrysanthemum indicum Linne flowers was analyzed and found to markedly decrease AChE activity. Acaciin and acacetin-7-O-B-D-galactopyranoside were identified as the active compounds responsible for the AChE inhibition by using an activity-guided fractionation strategy. The relationship between structure and activity for five flavonoids (acaciin,acacetin-7-O-B-D-galactopyranoside , luteolin, and two other commercially available flavonoids, i.e., apigenin and acacetin) was also investigated, revealing that the presence of methoxy groups at C-4' in the B ring and a sugar at O-7 in ring A appear to be essential for the inhibition of AChE.

TL;DR: Results indicate that ingesting C. indicum flower oil produces no acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation, with or without the introduction of a metabolic activation system.
Abstract: Chrysanthemum indicum is widely used to treat immune-related and infectious disorders in East Asia. C. indicum flower oil contains 1,8-cineole, germacrene D, camphor, α-cadinol, camphene, pinocarvone, β-caryophyllene, 3-cyclohexen- -ol, and γ-curcumene. We evaluated the safety of C. indicum flower oil by conducting acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation tests. Mortality, clinical signs and gross findings of mice were measured for 15 days after the oral single gavage administration of C. indicum flower oil. There were no mortality and clinical signs of toxicity at 2,000 ㎎/㎏ body weight/day of C. indicum flower oil throughout the 15 day period. Micronucleated erythrocyte cell counts for all treated groups were not significantly different between test and control groups. Levels of 15.63∼500 μg C. indicum flower oil/plate did not induce mutagenicity in S. Typhimurium and E. coli, with or without the introduction of a metabolic activation system. These results indicate that ingesting C. indicum flower oil produces no acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation.

TL;DR: In this article, the antioxidant activity and content of catechins in commercial gamguk teas were determined for optimum elution conditions for determining the elution of water-soluble substances from herbal teas.
Abstract: Determining the elution of water-soluble substances from herbal teas is an important factor in their efficient use in terms of taste, perfume, and content of health-related components. The antioxidant activity and content of catechins in commercial Chrysanthemum indicum (gamguk) teas were determined for optimum elution conditions. The water extract of gamguk teas did not differ significantly in yield compared to methanol extracts and showed stronger antioxidant activity. Catechin contents in gamguk teas were 8-18% of the extracts when individual peaks in high-performance liquid chromatography analysis were compared to standard catechin peaks. Gamguk teas exhibited faster release of antioxidants, and the antioxidant activity was positively correlated with the thermal treatments. Gukhwacha (GC) was the best tea for rapid release (30 sec) of antioxidants with the 50oC treatment, whereas antioxidants in other teas were relatively slower released.

TL;DR: CILE could attenuate cisplatin-induced nephrotoxicity and might be a beneficial agent for acute renal failure management and some major constituents were quantitatively analyzed.
Abstract: Chrysanthemum indicum Linne has been used in traditional medicine to treat various inflammatory diseases in East Asia. The aim of the present study was to investigate the protective effect of C. indicum ethanol extract (CILE) against cisplatin-induced nephrotoxicity. An HPLC-photodiode array method was used for fingerprint analysis of the CILE and ten major constituents were quantitatively analyzed. The protective effect of CILE on cisplatin-induced nephrotoxicity was assessed using both in vitro (porcine kidney cell; PK15 cell) and in vivo (Sprague Dawley rat) experiments. In the in vitro study, CILE enhanced PK15 cell viability after cisplatin treatment with recovered antioxidant status. Moreover, the increased p53 expression after cisplatin treatment was decreased in the CILE pretreated cells. In the in vivo study, SD rats were treated for 28 consecutive days with CILE (0, 100, 300 and 500 mg/kg). On day 23, a single dose of cisplatin (5 mg/kg) was injected to induce nephrotoxicity. The CILE pretreated group showed recovered serum renal function index with ameliorated oxidative stress. Histopathological alterations and apoptosis in the kidney were also decreased in CILE pretreated rats. Taken together, CILE could attenuate cisplatin-induced nephrotoxicity and might be a beneficial agent for acute renal failure management.

TL;DR: In this paper, the volatile composition of the essential oil from fresh gamguk (Chrysanthemum indicum) flowers was investigated and the volatile constituents were extracted by the hydro distillation method.
Abstract: The volatile composition of the essential oil from fresh gamguk (Chrysanthemum indicum) flowers was investigated. The volatile constituents were extracted by the hydro distillation method. Volatile compositional changes of gamguk prepared via different drying methods (shade- and freeze-drying methods) were also determined. Total 36, 63, and 55 volatiles constituents were confirmed in the essential oil from fresh and shade-, and freeze-dried flowers. Ketones were predominant in the volatiles of gamguk flowers (%): fresh, 43.8; shade dried, 30.3; and freeze dried, 36.1. Camphor was the most abundant volatile component in all samples, and the content of borneol was also remarkable. The content of camphor was higher in fresh sample than those of dried samples while borneol concentration was significantly increased in the dried samples.
