Objective:
Liuwei Dihuang (LWDH) is a famous traditional herbal medicine formula in China that may regulate the balance of kidney yin yang and has been used to restore functional insufficiency of the kidney for a long time in China.
Methods:
In this study, the water extract of LWDH was tested for its α-Amylase and α-Glucosidase inhibitory activities, and its anti-diabetic property in streptozotocin (STZ)-induced diabetic mice was also analyzed.
Results:
LWDH extract inhibited α-Glucosidase and α-Amylase activities in a dose- dependent manner. Treatment of streptozotocin-induced diabetic mice with LWDH extract decreased camp, fasting blood glucose, TC, TG, LDL-c, HbA1C, Urine volume levels and Urine sugar, increased HDL-c level when compared to STZ induced diabetic mice.
Conclusion:
This study demonstrates that extract of LWDH can inhibit α-amylase and α-glucosidase activities and shows anti-diabetic effect in a mice preclinical model.

The reaction involving bases like EtO− whose conjugate acid EtOH (pKa = 15.9) is stronger than the ketone (pKa = 19.2) results in an equilibrium mixture with higher ketone concentration. As a consequence,...

Acid-Catalyzed α-Halogenation of Aldehydes and Ketones
In the first step of the mechanism, the acid protonates the carbonyl oxygen resulting in a resonance-stabilized cation, which subsequently loses an α-hydrogen to form an enol tautomer. The C=C bond in an enol is highly nucleophilic because of the electron-donating nature of the –OH group. Consequently, the double bond attacks an electrophilic halogen to form a...
