Synthesis and antioxidant activity of hispolon, a yellow pigment from Inonotus hispidius^†

Mon, 01 Apr 2002 00:00:00 GMT

Title: Synthesis and antioxidant activity of hispolon, a yellow pigment from Inonotus hispidius^† Authors: Venkateswarlu, S; Ramachandra, M S; Sethuramu, K; Subbaraju, Gottumukkala V Abstract: Hispolon 5 has been synthesised from veratraldehyde 1, in four steps, with an overall yield of 23%. The spectral data of synthetic 5 are in agreement with those of natural 5. Hispolon shows strong antioxidant and weak antibacterial activities. Page(s): 875-877
