Dioscorea Gracilis is Mainly Derived from Dioscorea Gracilis

Source and extraction method：

Source: Mainly from Dioscorea gracillima, a plant of the Dioscoreaceae family. Dioscorea gracillima is a twining herbaceous vine. Its rhizome is slender, cylindrical, and has a brownish-yellow outer skin. The stem is left-handed and hairless. The leaves are alternate, with ovate-cordate leaves, gradually pointed at the apex, cordate at the base, and entire or wavy margins. The flowers are unisexual, dioecious, with male inflorescences in spikes and female inflorescences in spikes. Its rhizome is the main part for extracting Dioscorea gracillima saponins.

Extraction method:

Solvent extraction method: Organic solvents such as ethanol and methanol are often used to extract the rhizome of Dioscorea gracillima. For example, after the rhizome is dried and crushed, it is soaked in an ethanol solution of appropriate concentration and heated to reflux to dissolve the Dioscorea gracillima saponins in the solvent. After filtering, concentration and other operations, an extract containing Dioscorea zingiberensis is obtained, and then further purified by column chromatography, recrystallization and other means to obtain high-purity Dioscorea zingiberensis.

Ultrasonic assisted extraction method: The cavitation effect of ultrasound is used to accelerate the dissolution of Dioscorea zingiberensis from the rhizome. The rhizome powder is placed in a suitable solvent (such as an ethanol-water mixed solvent) and extracted using an ultrasonic device. The extraction time, temperature and other conditions can be optimized according to the experiment. This method not only has high extraction efficiency, but also reduces the use of solvents.

Product Information

Gracillin is a steroidal saponin, whose chemical structure is based on steroidal sapogenin and connected to sugar chains. The steroidal sapogenin part has a typical spirostanol or isostanol structure, and the sugar chain part contains monosaccharides such as glucose and rhamnose, with a molecular formula of. This structure gives it special physical and chemical properties and biological activity.

Physical properties: It is usually a white powdery substance, odorless, and slightly bitter. In terms of solubility, gracillin has a certain solubility in water, good solubility in organic solvents such as methanol and ethanol, and poor solubility in non-polar organic solvents such as chloroform and ether. Its melting point is around 275-277℃.

Chemical properties: Because it contains glycosidic bonds, gracillin may undergo hydrolysis in an acidic or alkaline environment to produce sapogenin and sugar. This hydrolysis characteristic will affect its chemical stability and biological activity, and needs to be considered in the process of drug development and formulation.
