Citrus fruits have been known and valued for their aroma in food and perfume ever since humans have maintained written records. Often described as the "champagne" of citrus oils, especially cold pressed lime peel oils have raised attention. Particularly peel oils of Citrus latifolia exhibit a pleasant coumarinic, sweet, and balsamic aroma in comparison to its close relative, the Citrus aurantifolia. Those coumarinic notes have not been completely understood until today. Thus, this study aimed to identify the responsible substances and elucidate their contribution and impact on the aroma of cold-pressed lime oil. By combining distillation, fractionation, olfactory detection, and structure elucidation, the responsible key aroma components were identified. A combination of coumarins and their corresponding saturated analogs have been identified to significantly contribute to the typical coumarinic-like aroma, including three new flavor compounds that have not yet been described in the literature as lime oil constituents: 7-methoxy-2-chromanone (3,4-dihydro-7-methoxy-2H-1-benzopyran-2-one; CAS 20921-02-2), 5,7-dimethoxy-2chromanone (3,4-dihydro-5,7-dimethoxy-2H-1-benzopyran-2-one; CAS 82243-01-4) and 5,6-dihydrobergaptene (5,6-dihydro-4methoxy-7H-furo[3,2-g][1]benzopyran-7-one; CAS 29050-61-1). The sensorial evaluation of the impact of these components on the lime aroma profile has shown flavor-modulating effects and the ability to enhance aldehydic-peely, juicy, and fruity notes as well as their importance in reproducing the authentic, typical coumarin-like notes.

Matricaria pubescens is traditionally used as a postpartum antihemorrhagic and to treat digestive disorders. The aim of this study is to determine the total amounts of phenols, flavonoids, condensed tannins, hydrolysable tannins, anthocyanins and total antioxidant capacity of samples from different regions and periods in Algeria in order to guide the selection of varieties and the period of harvest. The analysis was carried out by Ferric reducing antioxidant power (FRAP) and DPPH radical scavenging capacity. The methanolic extracts of the aerial parts of 8 varieties of Matricaria pubescens were tested. The results indicated that these varieties had strong radical scavenging capacity as well as a strong reducing antioxidant power. The average contents of polyphenols, flavonoids, condensed tannins, hydrolysable tannins and anthocyanins were 1.58 ± 0.33, 38.44 ± 10.77, 0.63 ± 0.2, 1.22 ± 1.55 and 0.39 ± 0.13 mg/g of dry matter, respectively, with the highest contents found in the samples harvested from the region of Ouargla. The Ferric reducing antioxidant power was positively correlated with the contents of hydrolysable tannins which play a major role in the antioxidant properties. Samples were divided into two groups by cluster analysis and variables measured. These results are useful for the selection of varieties and as guidance for their harvest.

“…Analysis of the aerial parts of M. pubescens revealed the presence of two coumarins and an isobutyl amide (Benkiki 2006). The aqueous extracts of the aerial part showed the presence of alkaloids, saponins, flavonoids, and terpenes (Gherboudj et al 2012;Makhloufi et al 2012).…”

Abstract. Mekhadmi NE, Ramdani M, Lograda T, Chalard P, Figueredo G. 2019. Chemotypes and antibacterial activity of Matricaria pubescens of Algeria. Biodiversitas 20: 3170-3179. The objectives of this study were to determine the chemical composition and to evaluate the antibacterial activity of Matricaria pubescens L. essential oils from 14 sampling locations in southern Algeria. The extraction of essential oils was carried out by the hydro-distillation; the analysis of chemical composition of essential oil was carried out by GC-MS. Antibacterial activity was performed by disc diffusion method at the undiluted and diluted essential oil (1/1, 1:2, 1:4 and 1:8 v:v of DMSO) against eight species of bacteria (Bacillus cereus, Escherichia coli, Klebsiella pneumoniae, Listeria innocua, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella enterica and Staphylococcus aureus). The results showed that the average yields of essential oils were 0.4 ± 0.27%. A total of 34 components were identified, averaging 99.22 ± 0.8% of the total oils. The main components were β-ocimene (Z) (47.41 ± 13.67%), α-pinene (19 ± 7.36%), β-bulnesene (4.96 ± 10.6%), ocimene-allo (4.46 ± 1.3%), 1-phenyl-penta-2,4-diyne (4.06 ± 5.7%), limonene (3.84 ± 1.8%), caryophyllene oxide (2.36 ± 3.6%) and γ-bisabolene-E (2.08 ± 4.3%). Based on the UPGMA cluster analysis, there were two distinct clades of M. pubescens. This species has a chemical polymorphism with different chemotypes marked in nature. There were four chemotypes identified in the essential oil of M. pubescens in the region studied. The essential oil of M. pubescens has antibacterial activity against eight bacteria tested in a concentration-dependent manner.
