Gullarni ekstraktsiya qilish – Yumshoq ishlov berish, sonication orqali yuqori hosil
Whether you want to make an absolute, flower-infused water or blossom hydrolat, sonication helps you to increase the yield of your flower extract. Learn why sonication is the ideal extraction technique to isolate the delicate biomolecules and essential oils from flowers and petals.
Sonication as Ideal Extraction Technique for Biomolecules and Essential Oils from Flowers and Blossoms
As flowers contain many fragrant, flavorful and therapeutically active compounds, which can be used as ingredients for medicinal products, food, cosmetics and nutritional supplements, they are a highly coveted raw material for potent extracts. Ultrasonic extraction is a potent technique to isolate the desired substances from blossoms. Hence, flowers are a very delicate part of a plant and require accordingly careful treatment. Here come the mild extraction conditions of ultrasonication to the fore. As non-thermal, precisely controllable extra method, sonication produces high yields of flower extracts. Outstanding extract quality and high efficiency are key characteristics of ultrasonic botanical extraction.
Rose Water by Sonication – A Step-by-Step Instruction
To prepare rose water as demonstrated in the video clip above, follow the instruction described here:
- To begin, carefully select fresh roses (Rosa damascena) and remove the petals from the flower pistil. Cut the petals into smaller pieces in order to increase the surface area.
- Since we want to make rose water, we use purified water as solvent.
- Place the petals into a glass beaker and add water. In the video we use the large 10 petals and 200mL water.
- Set up the UP200Ht sonicator: Mount the sonotrode S26d14 tightly. Since petals are a very delicate plant part, we adjust the amplitude to 70% so that all biomolecules are preserved during the ultrasonic extraction procedure.
- Immerse the probe into the glass beaker and turn the sonicator on. Sonicate for approx. 90 seconds.
- After sonication, filter the mixture to remove solid residues, obtaining clear and fragrant rose water.
- Collect the rose water in sterile containers for storage and store it in a cool, dark place to maintain its quality and extend its shelf life.
- Use the rose water for culinary or cosmetic applications.

Essential Oil Extraction using Sonication
Ultrasonically-assisted hydrodistillation is an advanced extraction technique that combines traditional hydrodistillation with ultrasound technology. This method utilizes ultrasonic waves to create cavitation, forming small vapor-filled bubbles that implode, generating microjets and turbulence. These effects enhance particle breakdown, surface cracking, and mixing, thereby significantly improving mass transfer rates.
The process also incorporates bulk heating, which accelerates the vaporization of water and enhances heat transfer. This combined approach reduces extraction time, energy consumption, and solvent use, making ultrasonically-assisted hydrodistillation more efficient and environmentally-friendly compared to conventional methods.
Key benefits of ultrasonically-assisted hydrodistillation include:
- Higher Extraction Efficiency: Enhanced release of essential oils and valuable bioactive compounds.
- Reduced Time and Energy: Shorter extraction times and lower energy consumption.
- Yaxshilangan sifat: Preservation of compound integrity due to gentle processing conditions.
- Operational Advantages: Safe operation, lower startup time, reduced equipment size, and fewer processing steps.
The comparing SEM images above show the cell structure of Satureja leaves treated by hydrodistillation (left) and ultrasonically-assisted hydrodistillation (right) and reveals the significantly more efficient disruption of cell walls by the ultrasonic treatment. As a result, ultrasonic hydrodistillation enhances in essential oil extraction by approx. 40 % compared to conventional hydrodistillation.

What is the difference between rose water, rose absolute and rose hydrolat?
Rose water, rose absolute, and rose hydrolat are all derived from roses, but they differ in their production methods and chemical composition.
Rose Water: Rose water is a byproduct of the steam distillation process used to extract rose essential oil. It contains the water-soluble components of the rose petals, imparting a delicate floral fragrance and flavor. Rose water is commonly used in culinary applications, skincare products, and aromatherapy due to its pleasant scent and potential health benefits.

Rose Absolute: Rose absolute is an aromatic oil extracted from rose petals through solvent extraction, usually with hexane or another solvent. This method is more efficient for extracting the fragrant compounds from the petals, resulting in a highly concentrated and fragrant oil.
Rose absolute is commonly used in perfumery and high-end cosmetic products for its intense and long-lasting floral scent.
Rose Hydrolat (Rose Floral Water):
Rose hydrolat, also known as rose floral water, rose hydrosol or rose distillate, is the water remaining after steam distillation of rose petals to extract rose essential oil. It contains water-soluble plant compounds as well as some of the essential oil molecules, giving it a mild fragrance and therapeutic properties. Rose hydrolat offers a similar aroma profile but has a more diluted water-based formulation.
Rose hydrolat is often used in skincare as a toner, facial mist, or ingredient in cosmetic formulations due to its hydrating, soothing, and refreshing qualities.
Each of these rose-derived liquids can be manufactures by ultrasonic extraction and has unique characteristics and benefits, which make them a precious ingredient in culinary, cosmetic, and therapeutics.
