“…The buds of clove, as well as the leaves, are also important plant parts for clove oil yield (Frohlich et al, 2019;Gaylor et al, 2014;Guan, Li, Yan, Tang, & Quan, 2007;Pino, Marbot, Agüero, & Fuentes, 2001). The previous study has reported that buds can produce a high-quality essential oil in terms of multiple useful chemicals other than eugenol (Alma, Ertaş, Nitz, & Kollmannsberger, 2007;El Ghallab et al, 2020;Lee & Shibamoto, 2001;Moemenbellah-Fard, Abdollahi, Ghanbariasad, & Osanloo, 2020;Moyler, 1993), though the dry mass of buds per plant is smaller than leaves.…”

Recently, clove plantation was mostly established in monoculture systems for production efficiency (Arimalala et al., 2019; Danthu et al., 2014; Martin, 1991). The frequent litter collection associated with intensive soil surface disturbances in a whole area of the crop field, however, is causing deterioration plant species diversity of ground vegetation. Therefore, mixed culture by intercropping of clove with other crop species is suggested as an alternative method which would reduce the impact of frequent litter collection on biodiversity of ground vegetation for sustainable management of clove production. Though the mixed culture is expected to have ecological advantages in terms of biodiversity conservation, at the same time, it will also bring inter-species competition of resources such as light or soil water (

“…For example, the extract of mango peel has been used as a natural antioxidant in sunflower oil to control lipid oxidation; the optimal conditions were 25 MPa, 60 °C and 15% ethanol in water by using a Box–Behnken design [ 92 ]. Supercritical fluid extraction is also applied in the extraction of cholesterol and other lipids from egg yolk [ 116 ], extraction of lipids and cholesterol from meat and meat products [ 117 ], decaffeination of coffee and tea [ 24 , 118 , 119 ], extraction of hops [ 71 , 120 , 121 ], extraction of bioactive compounds [ 65 , 91 , 101 , 102 ], extraction of free amino acids [ 122 ], extraction of lipids and cholesterol from fish [ 123 ], extraction of natural glycosides [ 124 ], fractionation of natural colorings, natural flavorings, and fragrances from several foodstuffs [ 99 , 125 ], and the separation of spices and essential oils [ 82 , 83 , 84 , 85 , 86 ].…”

Recent Advances in Supercritical Fluid Extraction of Natural Bioactive Compounds from Natural Plant Materials

In this review, recent advances in greener technology for extracting natural bioactive components from plant origin sources are discussed. Bioactive compounds of plant origin have been defined as natural chemical compounds present in small amounts in plants. Researchers have shown interest in extracting bioactive compounds because of their human health benefits and characteristics of being eco-friendly and generally recognized as safe. Various new extraction methods and conventional extraction methods have been developed, however, until now, no unique approach has been presented as a benchmark for extracting natural bioactive compounds from plants. The selectivity and productivity of traditional and modern extraction techniques generally depend on selecting the critical input parameters, knowing the nature of plant-based samples, the structure of bioactive compounds, and good scientific skills. This work aims to discuss the recent advances in supercritical fluid extraction techniques, especially supercritical carbon dioxide, along with the fundamental principles for extracting bioactive compounds from natural plant materials such as herbs, spices, aromatic and medicinal plants.

“…In particular, eugenol and minor constituents like methyl salicylate and methyl amyl ketone are responsible for the characteristic pleasant aroma of cloves. The extraction of phytochemicals, achievable with high efficiency by presoaking and the liquid ammonia treatment of plant materials [ 80 ], in the case of cloves was realized with different operating conditions, including using supercritical CO 2 [ 81 ] .…”

The current COronaVIrus Disease 19 (COVID-19) pandemic caused by SARS-CoV-2 infection is enormously affecting the worldwide health and economy. In the wait for an effective global immunization, the development of a specific therapeutic protocol to treat COVID-19 patients is clearly necessary as a short-term solution of the problem. Drug repurposing and herbal medicine represent two of the most explored strategies for an anti-COVID-19 drug discovery. Clove (Syzygium aromaticum L.) is a well-known culinary spice that has been used for centuries in folk medicine in many disorders. Interestingly, traditional medicines have used clove since ancient times to treat respiratory ailments, whilst clove ingredients show antiviral and anti-inflammatory properties. Other interesting features are the clove antithrombotic, immunostimulatory, and antibacterial effects. Thus, in this review, we discuss the potential role of clove in the frame of anti-COVID-19 therapy, focusing on the antiviral, anti-inflammatory, and antithrombotic effects of clove and its molecular constituents described in the scientific literature.
