Pelargonium Graveolens Stem Leaf Oil is a product of natural origin obtained from the stem and leaves of the shrub native to South Africa Pelargonium graveolens, botanical family Geraniaceae.
The name describes the structure of the molecule:
- "Pelargonium Graveolens" is the scientific name for the plant commonly known as rose geranium or sweet-scented geranium.
- "Stem Leaf Oil" indicates that the product is an essential oil obtained from the stems and leaves of the plant. The oil contains various aromatic compounds like citronellol, geraniol, and linalool, giving it a floral and rosy scent.
Uses. Pelargonium Graveolens Leaf Oil is widely used in perfumery for its distinctive scent. It also has antiseptic properties and is used in some skincare products.
Description of raw materials used in production and their functions.
- Pelargonium Graveolens stems and leaves. This plant is traditionally known for its distinct scent and is utilized in essential oil production. The oil has various uses in cosmetics, aromatherapy, and as an insect repellent.
- Solvents. Used in the steam distillation extraction process.
Step-by-step summary of industrial extraction process.
- Harvesting the stems and leaves. Pelargonium Graveolens stems and leaves are harvested at their peak oil concentration.
- Steams distillation. The stems and leaves undergo steam distillation to separate the essential oil from the plant material.
- Condensation and collection. The vapor containing the essential oil is cooled and condensed, allowing for the oil's separation and collection.
- Purification. The collected oil undergoes filtration or other methods to remove impurities.
What it is for and where
Medical
Phytochemical analysis of Pelargonium Graveolens oil revealed the presence of high levels of acyclic monoterpene alcohols, geraniol, citronellol, and linalool with antimicrobial (1) and antioxidant (2) activity.
Cosmetics
Perfuming. Unlike fragrance, which can also contain slightly less pleasant or characteristic odours, the term perfume indicates only very pleasant fragrances. Used for perfumes and aromatic raw materials.
CAS 90082-51-2
EC number 290-140-0
Commercial Applications
Perfumery. Pelargonium Graveolens Leaf Oil boasts a rose-like, floral scent and is widely used in perfumes, lotions, and other fragranced products.
Cosmetics and Personal Care. Due to its astringent and moisturizing properties, geranium oil is incorporated into various skin and hair care products.
Aromatherapy. Geranium oil is popular in aromatherapy for its purported balancing and relaxing properties.
Traditional Medicine
Historically, geranium oil has been tapped for addressing conditions such as anxiety, depression, and certain skin issues like acne and burns.

Abstract. Background: The aim of this study was to evaluate acetylcholinesterase inhibitory activity of some commonly used herbal medicine in Iran to introduce a new source for management of Alzheimer's disease. A total of 18 aqueous-methanolic extract (1:1; v/v) from the following plants: Brassica alba, Brassica nigra, Camellia sinensis, Cinchona officinalis, Citrus aurantifolia, Citrus x aurantium, Ferula assafoetida, Humulus lupulus, Juglans regia, Juniperus sabina, Myristica fragrans, Pelargonium graveolens, Pistacia vera, Punica granatum, Rheum officinale, Rosa damascena, Salix alba, and Zizyphus vulgaris were prepared and screened for their acetylcholinesterase inhibitory activity using in vitro Ellman spectrophotometric method. Results: According to the obtained results, the order of inhibitory activity (IC50 values, μg /ml) of extracts from highest to the lowest was: C. sinensis (5.96), C. aurantifolia (19.57), Z. vulgaris (24.37), B. nigra (84.30) and R. damascena (93.1). Conclusions: The results indicated and confirmed the traditional use of these herbs for management of central nervous system disorders. C. sinensis showed the highest activity in inhibition of acetylcholinesterase. However, further investigations on identification of active components in the extracts are needed.

Abstract. The essential oil of Pelargonium graveolens L. is valuable for its therapeutic benefits, so this study aimed to determine the synergistic effect of the combination of the essential oil of this plant with antibiotics instead of the extracts prepared with various solvents. In addition, the second goal of this study was to determine whether the essential oil combined with various antibiotics increased the overall killing activity in mouse macrophage cells with the aim of introducing an immunotherapeutic approach to the infection treatments used today. Herein, the volatile profile of Geranium oil (G.O) was analyzed using GC/MS. The current study sought to assess the synergistic characteristics of several antibiotic combinations using G.O against pneumococci, as well as the oil's antioxidant and antimicrobial activities. The major components of the oil were citronellol, geraniol, and isomenthone. In the combinations of G.O and antibiotics, the synergism of the Streptococcus pneumoniae to antibiotics advanced. When the time-kill data were evaluated, G.O + antibiotic combinations quickly diminished the viable cell count of S. pneumoniae from the 6th h. In this study, the combined use of existing antibiotics used in infection treatments with G.O could improve antibiotic effectiveness and thus prevent bacteria from developing antibiotic resistance.
