Description

technical field

[0001] The invention relates to a new application of the extract of Camellia oleifera, in particular to the application of the extract of Camellia oleifera in the preparation of medicines, health care products and daily chemical products, and in the treatment of diseases related to 5α-reductase. Background technique

[0002] 5α-reductase (5α-reductase, 5AR) is an NADPH-dependent enzyme that can catalyze testosterone (T) in vivo to generate more active dihydrotestosterone (DHT). Inhibiting the activity of this enzyme can reduce the generation of DHT, and then affect the diseases related to DHT, such as benign prostatic hyperplasia, prostate cancer, acne, male hair loss and so on. There are three isozymes of 5α-reductase, 5α-reductase I and 5α-reductase II and 5α-reductase III. Among them, type I enzymes are mainly expressed in non-reproductive tissues, such as liver and non-genital skin; type II enzymes are mainly expressed in reproductive tissues, such as pr...
