Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for skin whitening, comprising contacting a cell with a composition containing an effective amount of a  Chenopodium formosanum  ( Djulis ) extract obtained by extraction of a  Chenopodium formosanum  ( Djulis ) with an aqueous solvent. 
     
     
         2 . The method of  claim 1 , wherein the  Chenopodium formosanum  ( Djulis ) extract reduces or inhibits melanin production in the cell. 
     
     
         3 . The method of  claim 1 , wherein the total flavonoid content of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 1000 ppm. 
     
     
         4 . The method of  claim 1 , wherein the total polyphenol content of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 400 ppm. 
     
     
         5 . The method of  claim 1 , wherein the concentration of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 0.5 mg/mL. 
     
     
         6 . The method of  claim 1 , wherein the composition is a pharmaceutical composition, a health food composition, a food composition, or a cosmetic composition. 
     
     
         7 . A method for moisturizing skin, comprising contacting a cell with a composition containing an effective amount of a  Chenopodium formosanum  ( Djulis ) extract obtained by extraction of a  Chenopodium formosanum  ( Djulis ) with an aqueous solvent. 
     
     
         8 . The method of  claim 7 , wherein the  Chenopodium formosanum  ( Djulis ) extract shortens the gaps between a skin cell and another skin cell. 
     
     
         9 . The method of  claim 7 , wherein the  Chenopodium formosanum  ( Djulis ) extract promotes the expression of moisture-related genes. 
     
     
         10 . The method of  claim 7 , wherein the total flavonoid content of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 1000 ppm. 
     
     
         11 . The method of  claim 7 , wherein the total polyphenol content of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 400 ppm. 
     
     
         12 . The method of  claim 7 , wherein the concentration of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 0.5 mg/mL. 
     
     
         13 . The method of  claim 7 , wherein the composition is a pharmaceutical composition, a health food composition, a food composition, or a cosmetic composition. 
     
     
         14 . A method for scavenging free radicals in a cell, comprising contacting a cell with a composition containing an effective amount of a  Chenopodium formosanum  ( Djulis ) extract obtained by extraction of a  Chenopodium formosanum  ( Djulis ) with an aqueous solvent. 
     
     
         15 . The method of  claim 14 , wherein the total flavonoid content of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 1000 ppm. 
     
     
         16 . The method of  claim 14 . wherein the total polyphenol content of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 400 ppm. 
     
     
         17 . The method of  claim 14 , wherein the concentration of the  Chenopodium formosanum  ( Djulis ) extract equals or exceeds 0.5 mg/mL. 
     
     
         18 . The method of  claim 14 , wherein the composition is a pharmaceutical composition, a health food composition, a food composition, or a cosmetic composition.
