TL;DR: Evidence is provided beyond the traditional use of both Chrysanthemum indicum and C. morifolium as anti-infective agents that they could be used as spices in food and can be incorporated in different food products and pharmaceutical preparations as natural preservatives possessing antioxidant potential.
Abstract: The composition of essential oils of Chrysanthemum indicum and C. morifolium were comparatively studied using both Gas Chromatography/Flame ionization Detector (GC/FID) and Gas Chromatography/Mass spectrometry (GC/MS) analyses. The antiviral activity was determined using a plaque reduction assay against three common viruses namely, herpes simplex type-1 (HSV-1), hepatitis A (HAV) and vesicular stomatitis virus (VSV). The antimicrobial activity was assessed using agar diffusion and microdilution methods and the minimum inhibitory concentration (MIC) values were determined. In addition, the anti-mycobacterial evaluation was carried out using the Alamar blue assay and the effect against Helicobacter pylori was investigated. The anti-trypanosomal activity was evaluated using the resazurin method. GC investigations revealed that camphor is the major constituent of both oils accounting for 36.69 and 14.56% in the essential oils from C. indicum and C. morifolium, respectively. C. indicum was biologically more active in all experiments; it exhibited a notable antitrypanosomal activity with an IC50 value equals 45.89 μg/mL and a notable antimicrobial activity versus Streptococcus agalactiae with a MIC value of 62.5 μg/mL. It also inhibited the replication of VSV with an IC50 value of 3.14 μg/mL. Both oils revealed antioxidant potential with IC50 values of 2.21 and 2.59 mg/mL for C. indicum and C. morifolium, respectively. This study provides evidence beyond the traditional use of both Chrysanthemum indicum and C. morifolium as anti-infective agents. Thus they could be used as spices in food and can be incorporated in different food products and pharmaceutical preparations as natural preservatives possessing antioxidant potential.

TL;DR: In vitro data suggest that the essential oil of C. indicum with other antibiotics may be microbiologically beneficial and synergistic and a strong bactericidal effect was exerted in drug combinations.
Abstract: The chemical components of the essential oil obtained from Chrysanthemum indicum L. were analyzed by GC-MS. Seventy-three compounds accounting for 96.65% of the extracted essential oil were identified. The main compounds in the oil were α-pinene (4.4%), 1,8-cineole (10.4%), α-thujone (6.05%), camphor (10.12%), terpinen-4-ol (3.4%), bornyl acetate (6.1%), borneol (3.6%), cis-chrysanthenol (3.4%), β-caryophyllene (5.1%), germacrene D (10.6%), and α-cadinol (3.0%). The essential oil of C. indicum exhibited stronger antibacterial activity against all oral bacteria tested (MICs, 0.1 to 1.6 ㎎/㎖; MBCs, 0.2 to 3.2 ㎎/㎖) than their major compounds. Furthermore, the MICs/MBCs were reduced to one half ~ one sixteenth as a result of the combinations included the essential oil with ampicillin or gentamicin for all oral bacteria. A strong bactericidal effect was exerted in drug combinations. The in vitro data suggest that the essential oil of C. indicum with other antibiotics may be microbiologically beneficial and synergistic.

TL;DR: Findings give rise to the assumption that the other, as yet unidentified sesquiterpene lactones of this flower also belong to the guaianolide type.
Abstract: Experimental and chemical studies in guinea pigs on contact allergy caused by Chrysanthemum indicum L. (Chrysanthemum of the florists) led to the isolation of several sesquiterpene lactones. From the crude extract of dried flowers 12 fractions were obtained of which four gave strong reactions on epicutaneous application to guinea pigs sensitized with an extract of C. indicum L. One of these allergens was identified as a sesquiterpene lactone of the guaianolide type. It is identical to Arteglasin-A derived from Artemisia douglasiana Bess. The occurrence of Arteglasin-A in Chrysanthemum indicum L. as well as its allergenic properties are described forthe first time. These findings give rise to the assumption that the other, as yet unidentified sesquiterpene lactones of this flower also belong to the guaianolide type.

TL;DR: The advances in botany, phytochemistry, and pharmacology of C. indicum L were reviewed and it is hoped that this review can provide important information for traditional Chinese medicine, phyllochemistry, synthetic and medicinal chemistry researchers for making full use of this plant.
Abstract: Chrysanthemum indicum L. (C. indicum L.), a member of the Compositae family, is a perennial plant that has been used as a traditional medicine for more than 2000 years in China and is widely used for the treatment of Pemphigus, swelling, pain, and scrofula. To date, more than 190 chemical constituents have been isolated and identified from this plant, including flavonoids, terpenoids, phenylpropanoids, and phenolic acids. Numerous modern studies have shown that extracts or monomeric compounds from C. indicum L. have several pharmacological activities, such as anti-inflammatory anti-oxidation, antipathogenic microorganism, anticancer, immune regulation, and hepatoprotective effects. However, resource availability, the research on the mechanism, and quality control are still insufficient, which deserves further efforts. In this paper, the advances in botany, phytochemistry, and pharmacology of C. indicum L were reviewed. We hope that this review can provide important information for traditional Chinese medicine, phytochemistry, synthetic and medicinal chemistry researchers for making full use of C. indicum L. resource.

TL;DR: A mechanistic study revealed that the potential anti-inflammatory activity of compound 1 appears to be mediated via suppression of an LPS-induced NF-κB pathway and down-regulation of MAPK activation.
Abstract: Ten new highly oxidized monomeric (1–8) and dimeric guaianolides (9 and 10), along with two known guaianolide derivatives (11 and 12), were isolated from the aerial parts of Chrysanthemum indicum using a bioassay-guided fractionation procedure. The new compounds were characterized by the basic analysis of the spectroscopic data obtained, and the absolute configurations were determined by both empirical approaches and ECD calculations. Inhibitory effects of 1–12 on nitric oxide production were investigated in lipopolysaccaride (LPS)-mediated RAW 264.7 cells, and most of them (1–8 and 11) displayed IC50 values in the range 1.4–9.7 μM. Moreover, a mechanistic study revealed that the potential anti-inflammatory activity of compound 1 appears to be mediated via suppression of an LPS-induced NF-κB pathway and down-regulation of MAPK activation.
