Abstract: A honokiol liposome transdermal gel includes by weight percentage: 1-40% honokiol liposome and 10-85% gel matrix. The honokiol liposome comprises phospholipid, honokiol, cholesterol, and polyethylene glycol or pegylated phospholipid, in a weight ratio of 2-10:1:0.3-0.6:0.1-0.3; and the gel matrix is poloxamer. The invention achieves an encapsulation efficiency of honokiol greater than 90%, the honokiol liposome transdermal gel has high transdermal efficiency, rapid and sustained absorption, and high stability, and shows good therapeutic effects for skin diseases.

Abstract: The present invention provides honokiol crystal forms A, B and C and amorphous form and a preparation method thereof, wherein the preparation method comprises dissolving honokiol in n-heptane and standing at room temperature overnight to obtain the separated crystal as honokiol crystal form A; heating the honokiol crystal form A and cooling to room temperature to obtain a solid as honokiol crystal form B; heating the honokiol crystal form A to the molten state and then standing at quenching temperature to obtain the separated crystal as honokiol crystal form C; and adding the honokiol crystal form A with an antisolvent in DMSO/H2O system, and thus obtaining the oily matter as honokiol amorphous form. The honokiol crystal forms A, B and C and the amorphous form of the present invention have the advantages of good solubility, good stability, low hygroscopicity, long-term storage and/or good reproducibility, and are suitable for drug development.
