Classification of Korean Chrysanthemum species based on volatile compounds using cluster analysis and principal component analysis

Abstract

In the analysis of chemotype relationship among Korean Chrysanthemum species, the volatile compounds in the leaves of 15 taxa were analyzed and identified by gas chromatograph/mass spectrometry. Principal component analysis and cluster analysis used for the grouping based on the volatile compounds. Fifteen taxa of Charysanthemum species were categorized into three groups. Groups I and II included higher ketones than Group III. Group I had five C. zawadskii subspecies: acutilobum, acutilobum var. tenuisectum, acutilobum var. alpinum, lucidum, and coreanum. Five C. zawadskii subspecies were analyzed with main volatile compounds of D-limonene and m-thymol. Group II consisted of four C. zawadskii subspecies including naktongense, yezoense, latilobum, and latilobum var. leiophyllum, and one species C. makinoi. They consisted of main compounds of linalool, cischrysanthenol, eugenol, and chrysanthenone. Group III included five C. indicum species and related species: C. indicum, var. albescens, var. acuta, C. boreale, and C. lineare. The present study was able to classify volatile compounds of Korean Chrysanthemum species attributable to major compounds, such as hydrocarbons (sabinene, cymene, β-selinene), alcohols (1-octen-3-ol, cischrysanthenol, hinesol), ketones (chrysanthenone, camphor), and esters (cis-sabiene hydrate, trans-chrysanthenyl acetate).

Botrytis cinerea infection in three cultivars of chrysanthemum in ‘Alchimist’ and its mutants: Volatile induction of pathogen-infected plants

“…The findings on the content of VOCs and other secondary metabolites in Chinese chrysanthemum flowers revealed 58 volatile compounds (Sun et al, 2010). Kim et al (2014) analyzed the volatile compounds extracted from leaves from fifteen taxa of Korean Chrysanthemum species. With the chemotypes received, they were able to classify the taxa tested into three groups, different in terms of the quantity of particular secondary compounds.…”

Geographical origin identification and quality control of Chinese chrysanthemum flower teas using gas chromatography–mass spectrometry and olfactometry and electronic nose combined with principal component analysis

“…The HuaiJu teas exhibited the highest total content of volatile components (2671.13 μg g −1 ), followed by XueJu (2014.66 μg g −1 ), BoJu (1957.01 μg g −1 ), HangJu (1742.57 μg g −1 ) and FuJu (1742.48 μg g −1 ). The differences revealed that the volatile components of chrysanthemum flower teas were affected by their origins (Kim et al ., ).…”

“…Scores and loadings identified the correlation between sample classification and aroma notes (aroma‐active components) (Kim et al ., ; Yao et al ., ). As shown in Fig.…”

Protective Effect of Chrysanthemum boreale Flower Extracts against A2E-Induced Retinal Damage in ARPE-19 Cell

“…Anthocyanins from blueberries prevented A2E-induced cytotoxicity by reducing A2E-epoxidation. Some volatile compounds, including camphor, borneol, α-pinene, camphene, 1,8-cineole, germacrene-D, α-thujene, α-muurolene, piperitol, and hinesol, were identified in the essential oils of the CB flowers [52,53]. The essential oil of CB flowers is usually extracted by steam distillation, which vaporizes water and is obtained by redissolving it in an organic solvent.…”
