The invention discloses a walnut
diaphragma juglandis phenolic extract, which is characterized in that the content of flavone in the phenolic extract is 64.5-66.1%, the walnut
diaphragma juglandis phenolic extract has the effect of preventing
abnormal glucose and
lipid metabolism, and the phenolic extract is obtained by pretreatment, extraction, separation, concentration,
drying and determination. The walnut
diaphragma juglandis
phenol low-
dose extract and the walnut diaphragma juglandis
phenol high-
dose extract can remarkably inhibit impairment of
oral glucose tolerance of a model animal with
abnormal glucose and
lipid metabolism, remarkably reduce the damage degree of OGTT, remarkably inhibit increase of AUC, glycated
serum protein GSP, fasting blood glucose FBG,
fasting insulin FINS,
insulin resistance index HOMA-IR and
insulin sensitivity index ISI, and can be used for preparing the
medicine for treating the
abnormal glucose and
lipid metabolism. The rise of serum total
triglyceride TG,
total cholesterol TC and low-density
lipoprotein cholesterol LDL-C level and the reduction of the low-density
lipoprotein cholesterol HDL-C level of a model animal with abnormal glucose and lipid
metabolism are obviously inhibited. The walnut diaphragma juglandis
phenol extract is high in flavone content and can be used as a food or
feed additive and a human or animal
medicine raw material.
