摘要:An application of a pineapple extract composition in the preparation of a product having a whitening effect, the pineapple extract composition being prepared and obtained by extracting raw materials of the following components: pineapples, oat, highland barley, coix seeds, tremella polysaccharides and water. It has been proven by means of experimentation that the pineapple extract composition has an inhibiting effect on the activity of tyrosinase after acting on B16-F10 melanoma cells, and has a significant inhibitory effect on melanin synthesis of B16 cells.

标题 :Systems and methods for the synthesis of natural base steroidal hormones and more especially estrogens and progesterone and estrogen-like and progesterone-like compounds and their derivatives derived as phytohormones from herbaceous plants
发明人：PAGE ELLIOT W; RECTOR-PAGE LINDA G
摘要:Systems and methods for synthesizing natural base steroidal hormones and more especially estrogens and progesterone and estrogen-like and progesterone-like compounds and their derivatives which are derived in the form of phytohormones from herbaceous plants and formulated to provide a broad spectrum of estrogenic and/or progesterone activity for influencing physiological processes and biological functions. In particular, phytohormones (i.e. phytoestrogens and/or phytoprogesterone) are synthesized from herbaceous compounds selected from a group consisting of plants having a propensity for simulating estrogenic and/or progesterone hormonal activity that, when entering the bloodstream of a biological organism, either by means of oral ingestion, parenteral injection, or topical application, have a tendency to enhance, supplement and/or maintain estrogen and/or progesterone hormonal levels by means of replacement therapy within a biological organism.
