• Phenolic Glycosides: Study of rhizomes isolated two new phenolic glycosides, aureaside A and B, together with seven known compounds, curculigoside I,5 orcinol glucoside ,6 curcapital,7 cimifugin prim-O-β- D-glucopyranoside, 8 2-O-β-D-apiofuranosyl (1→6)-O-β- D-glucopyranoside, 9 (2R,5S)-bornane-2,5-diol-2-O-β-D- glucopyranoside, 9 and bornyl 7-O-β-D-apio-D-furanosyl (1→6)-O-β-D-glucopyranoside.
• Radical Scavenging Activity / Tyrosinase Inhibitory Activity: Study showed a tuberous extract of H. aurea extracted by distilled water at room temperature gave high free radical scavenging activity and tyrosinase inhibition activity which was comparable to vitamin C as antioxidant and tyrosinase inhibitor agent. Results suggest potential for development of whitening cosmetic products.
• Anti-Melanogenesis / Collagen Biosynthesis Stimulating Activity Scavenging Activity: Study of H. aurea extracts for anti-melanogenesis and collagen biosynthesis stimulating activity. Results showed the leaves from H. aurea extracted by 95% ethanol can be applied as whitening and anti-aging agents for cosmetic pharmaceuticals.
