Determination of aloe emodin in Aloe vera extracts and commercial formulations by HPLC with tandem UV absorption and fluorescence detection

Extraction, Characterization and Properties of the Gel of Aloe Vera (Aloe barbadensis Miller) Cultivated in Chile

“…However, many accounts describe how the gel induces rapid healing of wounds and stimulates macrophages in the immune system. It is also known that the anthraquinones in the leaves can act as laxatives and as antifungal and antibacterial drugs [4][5][6]. Today it is accepted that the medicinal, cosmetics and nutritional properties of Aloe vera are due to the molecules the plant synthesizes.…”

Quantitative Detection of Aloin and Related Compounds Present in Herbal Products and Aloe vera Plant Extract Using HPLC Method

“…Aloe contains two major active materials: one is the aloe polysaccharides presenting in aloe filet; the other is anthraquinone derivatives existing in the leaves of different aloe plants [3]. The major constituents have multiple pharmacological actions including laxative, anti-bacterial, anti-inflammation, hemostatic, and antispasmodic [4][5][6][7][8][9]. These constituents are isolated by various extraction methods such as pressurized hot water extraction [10], ultrasonic and microwave extraction [11], supercritical CO 2 extraction [12], and pressurized liquid extraction [13].…”

Optimization of extraction condition for major iridoid components in fruit of corni (Cornus officinalis) by UPLC-PDA using response surface methodology

“…Accuracy was calculated by using the observed and nominal concentrations. The limit of detection (LOD) and limit of quantitation (LOQ) were calculated by using 3.3*σ/s and 10*σ/s, respectively, where σ is the standard deviation and s is slope of the regression equation (16)(17)(18)(19).…”
