2. Physical and chemical properties

[English name]: Sennoside A

【CAS】:81-27-6

【Molecular Formula】: C42H38O20

【Molecular weight】: 863.74

【Structural Formula】:

[Solubility]: yellow crystal (acetone), melting point 200~240 °C, optical rotation -164 ° (c=0.1, 60% acetone), optical rotation -147 ° (c=0.1, 70% acetone), optical rotation -24 ° (c=0.2, 70% dioxane). This product is insoluble in water, benzene, ether and chloroform; Slightly soluble in methanol, acetone and dioxane; Soluble in sodium bicarbonate aqueous solution. Microherb studies have shown that the solubility of this product increases rapidly in water-organic solvent homogeneous systems, up to 30% in optimal conditions.

[English name]: Sennoside B

【CAS】:128-57-4

【Molecular Formula】: C42H38O20

【Molecular weight】: 863.74

[Solubility]: light yellow prismatic crystal (acetone), melting point 180~186 °C, optical rotation -100 ° (c=0.2, 70% acetone), optical rotation -67 ° (c=0.4, 70% dioxane). The solubility is the same as sennoside A, but it is more solubility than sennoside A.
