“…β-Eudesmol is produced by plants such as Atractylodes lancea (Family: Asteraceae) [ 84 ] and Zingiber zerumbet (bitter ginger) [ 85 ], and has a wide range of bioactivities including antiangiogenicity [ 84 ], inhibition of Na + , K + -ATPase activity [ 133 ] and stimulation of feeding behavior in rats [ 134 ]. β-Cedrene is a component of Juniperus virginiana (eastern red cedar) essential oil [ 90 ] and the floral scent of Bearded Irises (Family: Iridaceae) [ 91 ]. β-Vatirenene has antioxidant activity and is produced by the plants Valeriana jatamansi (Family: Valerianaceae) [ 92 ] and Parthenium hysterophorus (Santa Maria feverfew) [ 93 ].…”

The Streptomyces produce a great diversity of specialized metabolites, including highly volatile compounds with potential biological activities. Volatile organic compounds (VOCs) produced by nine Streptomyces spp., some of which are of industrial importance, were collected and identified using gas chromatography–mass spectrometry (GC-MS). Biosynthetic gene clusters (BGCs) present in the genomes of the respective Streptomyces spp. were also predicted to match them with the VOCs detected. Overall, 33 specific VOCs were identified, of which the production of 16 has not been previously reported in the Streptomyces. Among chemical classes, the most abundant VOCs were terpenes, which is consistent with predicted biosynthetic capabilities. In addition, 27 of the identified VOCs were plant-associated, demonstrating that some Streptomyces spp. can also produce such molecules. It is possible that some of the VOCs detected in the current study have roles in the interaction of Streptomyces with plants and other higher organisms, which might provide opportunities for their application in agriculture or industry.

“…Both the composition and the amount of the volatiles determine the specific flower fragrance [19]. The number of volatiles emitted from P. mume is less than other species, such as bearded iris (219) [10], Lithophragma (132) [20], G. sempervirens (81) [8], but approximate to Lilium [6], P. mume hybrids, and Cymbidium [21]. Comprehensive analysis of the floral scent profiles indicates that the fragrance may be not straightly connected with the number of compositions but their concentration.…”

“…The composition and number of VOCs vary among different species or even in interspecific and intraspecific cultivars [4,5]. In recent years, more and more studies focusing on floral fragrance profiles have been performed in many fragrant plants, including Lilium [6,7], Gelsemium sempervirens [8], Chimonanthus praecox [9], Camellia [4], Polianthes tuberosa [5], and bearded irises [10], etc. VOCs released from these flowers are basically divided into four classes by the biosynthesis origin: terpenoids, phenylpropanoids/benzenoids, fatty acid derivatives, and compounds containing nitrogen/sulfur [11].…”

A Comparative Analysis of Floral Scent Compounds in Intraspecific Cultivars of Prunus mume with Different Corolla Colours

et al. 2019

Prunus mume is the only fragrant flowering species of Prunus. According to the previous studies, benzyl acetate and eugenol dominate its floral scent. However, the diversity of its floral scents remains to be elucidated. In this work, the floral volatiles emitted from eight intraspecific cultivars of P. mume with white, pink and red flowers, were collected and analyzed using headspace solid-phase microextraction combined with gas chromatograms-mass spectrometry (HS-SPME-GC-MS). In total, 31 volatile compounds were identified, in which phenylpropanoids/benzenoids accounted for over 95% of the total emission amounts. Surprisingly, except for benzyl acetate and eugenol, several novel components, such as benzyl alcohol, cinnamyl acohol, cinnamy acetate, and benzyl benzoate were found in some cultivars. The composition of floral volatiles in cultivars with white flowers was similar, in which benzyl acetate was dominant, while within pink flowers, there were differences of floral volatile compositions. Principal component analysis (PCA) showed that the emissions of benzyl alcohol, cinnamyl alcohol, benzyl acetate, eugenol, cinnamyl acetate, and benzyl benzoate could make these intraspecific cultivars distinguishable from each other. Further, hierarchical cluster analysis indicated that cultivars with similar a category and amount of floral compounds were grouped together. Our findings lay a theoretical basis for fragrant plant breeding in P. mume.

“…Indeed, industrial quality of essential oils is based on the specific composition in both qualitative and quantitative terms ( Nejad Ebrahimi et al, 2008 ; Nabiha et al, 2009 ). Scent composition is an important component of breeding in ornamentals such as Chrysanthemum or Iris ( Sun et al, 2015 ; Yuan et al, 2019 ). As ambient conditions may affect scent emission at the metabolic level and/or aroma accumulation and vaporization ( Hu et al, 2013 ; Farré-Armengol et al, 2014 ; Cna’ani et al, 2015 ), we have studied the effect of light and temperature on Narcissus scent.…”

The Effect of Post-harvest Conditions in Narcissus sp. Cut Flowers Scent Profile

et al. 2021

Narcissus flowers are used as cut flowers and to obtain high quality essential oils for the perfume industry. As a winter crop in the Mediterranean area, it flowers at temperatures ranging between 10 and 15°C during the day and 3–10°C during the night. Here we tested the impact of different light and temperature conditions on scent quality during post-harvest. These two types of thermoperiod and photoperiod. We also used constant darkness and constant temperatures. We found that under conditions of 12:12 Light Dark and 15-5°C, Narcissus emitted monoterpenes and phenylpropanoids. Increasing the temperature to 20°-10°C in a 12:12 LD cycle caused the loss of cinnamyl acetate and emission of indole. Under constant dark, there was a loss of scent complexity. Constant temperatures of 20°C caused a decrease of scent complexity that was more dramatic at 5°C, when the total number of compounds emitted decreased from thirteen to six. Distance analysis confirmed that 20°C constant temperature causes the most divergent scent profile. We found a set of four volatiles, benzyl acetate, eucalyptol, linalool, and ocimene that display a robust production under differing environmental conditions, while others were consistently dependent on light or thermoperiod. Scent emission changed significantly during the day and between different light and temperature treatments. Under a light:dark cycle and 15-5°C the maximum was detected during the light phase but this peak shifted toward night under 20-10°C. Moreover, under constant darkness the peak occurred at midnight and under constant temperature, at the end of night. Using Machine Learning we found that indole was the volatile with a highest ranking of discrimination followed by D-limonene. Our results indicate that light and temperature regimes play a critical role in scent quality. The richest scent profile is obtained by keeping flowers at 15°-5°C thermoperiod and a 12:12 Light Dark photoperiod.
