New neryl esters from Helichrysum italicum (Roth) G. Don (Asteraceae) essential oil

Helichrysum italicum (immortelle) is a dwarf aromatic shrub native to the Mediterranean region. The typical subspecies (italicum) produces an essential oil rich in neryl acetate and characteristic β-diketones, italidiones, highly valued in the perfume industry. As esters are an important group of aroma-active volatiles, herein the composition of the ester fraction of this immortelle chemotype essential oil was studied in detail. Chromatographic separation of Corsican immortelle essential oil enabled the discovery of numerous potentially olfactory-interesting esters of nerol and/or angelic acid, undetectable by direct GC-MS analyses of the unfractioned oil. Four esters of nerol and medium-chain branched fatty acids represent new natural products, while several other esters have a rather restricted occurrence in the Plant Kingdom.

Tyrosinase inhibitors

Methods and compositions are provided for inhibiting the activity of tyrosinase in a host and, as a result, inhibiting melanin-formation. The tyrosinase-inhibitor active ingredient is a compound or mixture of compounds represented by the following structural formulae (I) and (II): STR1 wherein the dotted lines at a, b, c, d, e, f, g, represent an optional double bond, provided that double bonds are not at both b and c, or at both f and g, at the same time; R1, R5, R6, and R7 are each hydrogen or methyl; R2 and R8 are each no group, or each hydrogen or hydroxyl when there is no double bond at a and at f, respectively; R3 is methylene when there is a double bond at b, or hydrogen or methyl when there is no double bond at b; R4 is formyl or --(CH2)n --R10, wherein R10 is hydrogen, hydroxyl, acyloxy, or cyano and n is an integer of from 1 to 3; and R9 is methylene when there is a double bond at g, or --(CH2)n --R10 when there is no double bond at g.
