“…Therefore, the quality of patchouli oil is measured based on the PA content in patchouli oil. The best quality of patchouli oil based on Indonesian national standards is with a minimum PA content of 30 % [2,[10][11][12].…”

“…The constituents with the highest levels are PA, soth at the quality of patchouli oil is largely determined by the levels of PA contained. PA content is more abundant in the leaves than in the stem or roots [9], and PA contained in patchouli oil can reach 30 % to 40 % (v v -1 ) [10]. The best quality of patchouli oil based on Indonesian national standards is a minimum PA content of 31 % [11].…”

Mini-Review: Extraction of Patchouli Oil from Pogostemon cablin Benth. Leaves

et al. 2023

Pogostemon cablin Benth. var ‘Sidikalang’ leaves are the main source of patchouli oil which is used in the cosmetics and perfume industry because of its better fixative nature and provides the foreign exchange of around 60 % of Indonesia’s essential oil export revenues and is the largest patchouli oil supplier in the world with a contribution of 90 %. But apparently, several studies found that patchouli oil also has pharmacological activity such as aromatherapy, anti-influenza, antioxidants, and anti-microbial. This proves that leaves patchouli oil can be used as alternative medicine. Patchouli oil is composed of 20 main constituents, but the most important role as a determinant of the quality of patchouli oil is sesquiterpene patchouli alcohol (PA). The right extraction method is the most important factor so that the quality of patchouli oil is well maintained during the extraction process. Some methods that have been used for patchouli oil extraction include soxhlet, hydrodistillation, microwave-assisted hydrodistillation, microwave–air hydrodistillation, and water–bubble distillation. Microwave-assisted hydrodistillation and water–bubble distillation methods are more efficient methods for patchouli oil extraction. The microwave-assisted hydrodistillation method produces a yield of 1.9437 to 2.7227 % with a PA content of 26.32 % within 120 min to 126 min, and the water–bubble distillation method produces a yield of 2.40 % with a PA content of 61.53 % within 360 min.

“…Cymbopogon citratus , lemongrass ( Figure 1 a), is a tufted aromatic herb native to India and Sri Lanka [ 28 ] that thrives in tropical and subtropical areas in South Africa and Central America [ 29 ]. Lemongrass is one of the most widely grown essential oil plants in many tropical and subtropical regions, used in the pharmaceutical, food and cosmetics industries [ 30 ].…”

Ornamental plant species introduced into new environments can exhibit an invasive potential and adaptability to abiotic stress factors. In this study, the drought stress responses of four potentially invasive ornamental grass species (Cymbopogon citratus, Cortaderia selloana, Pennisetum alopecuroides and P. setaceum) were analysed. Several seed germination parameters were determined under increasing polyethylene glycol (PEG 6000) concentrations. Additionally, plants in the vegetative stage were subjected to intermediate and severe water stress treatments for four weeks. All species registered high germination rates in control conditions (no stress treatment), even at high PEG concentrations, except C. citratus, which did not germinate at −1 MPa osmotic potential. Upon applying the water stress treatments, P. alopecuroides plants showed the highest tolerance, and C. citratus appeared the most susceptible to drought. Stress-induced changes in several biochemical markers (photosynthetic pigments, osmolytes, antioxidant compounds, root and shoot Na+ and K+ contents), highlighted different responses depending on the species and the stress treatments. Basically, drought tolerance seems to depend to a large extent on the active transport of Na+ and K+ cations to the aerial part of the plants, contributing to osmotic adjustment in all four species and, in the case of the most tolerant P. alopecuroides, on the increasing root K+ concentration under water deficit conditions. The study shows the invasive potential of all species, except C. citratus, in dry areas such as the Mediterranean region, especially in the current climate change scenario. Particular attention should be given to P. alopecuroides, which is widely commercialised in Europe as ornamental.

“…Rosemary has medicinal uses, but if the intention is to prepare essential oil from it, the flowering plant or its dry leaves should be used [6]. The biological activity of this plant is mainly related to its phenolic and volatile compounds such as carnosol and carnosic acid, Carnosol (Rosmarinic acid) found in the extract, and alphapinene (α-pinenebortyl acetate) and eucalyptol Camphor, Camphor Bornyl acetate found in the volatile oil of Eucalyptol [7].…”

Nanoparticles Based-Plant Protein Containing Rosmarinus officinalis Essential Oil; Fabrication, Characterization, and Evaluation

The toxicity risks, instability of essential oil, and complex composition are principal obstacles to using essential plant oil for clinical applications. Solving stability-related problems, providing targeted drug delivery, and decreasing plant essential oil toxicity, encapsulation can be used successfully. Rosemary (Rosmarinus officinalis) is a perennial plant of the Lamiaceae family with various healing properties. However, the rosemary essential oil, as volatile oil, is fast evaporated, which limits its applications. This study’s goal is to boost the prevent evaporation and bioactivity of rosemary essential oil by developing zein-NPs as a promising NDS (nano-drug-delivery system) and assessing the effect of NPs on the rosemary essential oil efficacy. Scanning electron microscopy (SEM) showed NPs sizes between 70–200 nm. With dynamic light scattering analysis (DLS), the average size of zein nanoparticle-containing rosemary essential oil (NPZLA) was obtained at ca. 154.5 nm. The entrapment efficiency (EE) on rosemary essential oil was ca. 71% inside the zein NPs. The in vitro release suggests that the polymeric barrier can control the rosemary essential oil release. Zein-NPs can be potentially used as NC (nanocarrier) for enhancing the evaporation inhibitor of ether oil of rosemary essential oil to enhance its bioavailability and performance further. It can be concluded that rosemary plant can be used as the core inside the nanoparticle by biological production method due to its medicinal properties and other properties. Based on the stated content, it is clear that in the future, by conducting more extensive research, the necessary platform can be provided for the use of this medicinal plant as much as possible in the pharmaceutical industry.
