Petroleum ether
Manufactured by Guangzhou Chemical
Sourced in China
Petroleum ether is a colorless, volatile, and flammable liquid used as a solvent in various laboratory applications. It is a mixture of aliphatic hydrocarbons, typically containing 5 to 12 carbon atoms. Petroleum ether has a low boiling point and is commonly used for extraction, cleaning, and degreasing purposes in laboratory settings.

To determine the surface oil content a powder with a mass (m 0 ) of 4.0 g was weighed in a triangular flask and immersed in 40 mL of 30-60℃ petroleum ether (Guangzhou Chemical Reagent Co. Ltd., Guangdong, China) and gently agitated for 1 min and immediately filtered with a G 3 core funnel. The filter residue was washed with 25 mL of petroleum ether for 40 s and filtered, and then the filtrate was transferred to a conical flask (m 1 ) . The petroleum ether was recovered and dried at 65℃ to a constant weight (m 2 ) and surface oil content (SOC) was calculated:
Peony seed oil content was measured by accurately weighted 4.0 g microcapsules and extracted by soxhlet extraction 23, 24) . Ether was selected as the extractant and extraction time was 6 h. After extraction, the solvent was evaporated completely and weighted to obtain the total quantity of oil extracted by ether. Encapsulation efficiency (EE％) was calculated as follows:
2.6 Determination of moisture content Determination of water content of peony seed oil microcapsule powder by thermogravimetric weight loss method. The measurement of the moisture content was slightly modified by referring to the method of Sani et al. 25) .

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
