“…This work also underlined how the LC 90 of carlina oxide does not lead to behavioral attraction or repellency responses in this key olive pest, despite the clear EAG responses recorded for both sexes. Due to the limited presence of C. acaulis in natural habitats, the industrial exploitation of its EO can be warranted by the production of the raw material through cultivation, even if the percentage of carlina oxide in the EO can be affected by cultural practices, such as substrate (hydroponics or field conditions) or fertilization [41,42]. Further studies on the evaluation of mammal safety and potential sub-lethal effects on insects of C. acaulis EO and carlina oxide are ongoing [43], as well as insights on the insecticidal activity of nanoformulations in which C. acaulis products are encapsulated to preserve their effectiveness over time [10,44] and their field validation.…”

Among botanical insecticides based on essential oils (EOs) or their main components, Carlina acaulis EO and the aromatic polyacetylene carlina oxide, constituting more than 90% of its EO, were recently proven to be effective against the larvae and adults of some insect vectors and pests. In this study, the toxicity of C. acaulis EO and carlina oxide were tested on Bactrocera oleae adults using a protein bait formulation. The LC50 values of the C. acaulis EO and carlina oxide were 706 ppm and 1052 ppm, respectively. Electroantennographic (EAG) tests on B. oleae adults showed that both carlina EO and oxide elicited EAG dose-dependent responses in male and female antennae. The responses to the EO were significantly higher than those to carlina oxide, indicating that other compounds, despite their lower concentrations, can play a relevant role. Moreover, Y-tube assays carried out to assess the potential attractiveness or repellency of carlina oxide LC90 to B. oleae adults showed that it was unattractive to both males and females of B. oleae, and the time spent by both sexes in either the control or the treatment arm did not differ significantly. Overall, this study points out the potential use of C. acaulis EO and carlina oxide for the development of green and effective “lure-and-kill” tools.

“…The more nitrogen is invested in soil, the less the accumulation of phenolics and flavonoids in Labisia pumila Benth (Ibrahim et al, 2011). Contradictory, previous studies reported that N shortage increased the content of carbon-based secondary metabolites (CBSMs) (e.g., polyphenols, flavonoids, and triterpenoids) (Ibrahim et al, 2013;Strzemski et al, 2021;Sun et al, 2021).…”

Herbal tea is a rich source of secondary metabolites which are reputed to have medicinal and nutritional efficacy. These secondary metabolites are influenced by the abiotic and biotic stresses that improve the production of herbal teas in terms of biomass production, accumulation and partitioning of assimilates of compounds. In this study, various examples of herbal teas have been shown to respond differently to secondary metabolites affected by environmental factors. Thus, the meta-analysis of this study confirms that different herbal teas' response to environmental factors depends on the type of species, cultivar, and the degree of shade that the plant is exposed. It is also evident that the metabolic processes are also known to optimize the production of secondary metabolites which can thus be achieved by manipulating agronomic practices on herbal teas. The different phenolic compound in herbal teas possesses the antioxidant, antimicrobial, antiatherosclerosis, anti-inflammatory, antimutagenic, antitumor, antidiabetic and antiviral activities that are important in managing chronic diseases associated with lifestyle. It can be precluded that more studies should be conducted to establish interactive responses of biotic and abiotic environmental factors on quality attributes of herbal teas.

“…Hence, the focus has currently been shifted to the cultivation of different therapeutically useful medicinal plants such as ashwagandha, opium, aloe, isubgol, aonla, medicinal solanum, stevia, etc. using sustainable approaches [21]. To achieve these, chemical fertilization is practiced in the cultivation of herbal plants which, however, due to challenges such as cost and harmful impacts on the biomass, yield and valuable metabolites are avoided in medicinal plant production systems [22].…”

Bioprospecting Plant Growth Promoting Rhizobacteria for Enhancing the Biological Properties and Phytochemical Composition of Medicinally Important Crops

Traditionally, medicinal plants have long been used as a natural therapy. Plant-derived extracts or phytochemicals have been exploited as food additives and for curing many health-related ailments. The secondary metabolites produced by many plants have become an integral part of human health and have strengthened the value of plant extracts as herbal medicines. To fulfil the demand of health care systems, food and pharmaceutical industries, interest in the cultivation of precious medicinal plants to harvest bio-active compounds has increased considerably worldwide. To achieve maximum biomass and yield, growers generally apply chemical fertilizers which have detrimental impacts on the growth, development and phytoconstituents of such therapeutically important plants. Application of beneficial rhizosphere microbiota is an alternative strategy to enhance the production of valuable medicinal plants under both conventional and stressed conditions due to its low cost, environmentally friendly behaviour and non-destructive impact on fertility of soil, plants and human health. The microbiological approach improves plant growth by various direct and indirect mechanisms involving the abatement of various abiotic stresses. Given the negative impacts of fertilizers and multiple benefits of microbiological resources, the role of plant growth promoting rhizobacteria (PGPR) in the production of biomass and their impact on the quality of bio-active compounds (phytochemicals) and mitigation of abiotic stress to herbal plants have been described in this review. The PGPR based enhancement in the herbal products has potential for use as a low cost phytomedicine which can be used to improve health care systems.
