Previous work has shown the presence of 5-n-tridecyl, 5-n-pentadecyl, 5-pentadeca-8-enyl and 5-pentadec-10enyl resorcinols in the wood [1] and of rutin, 2.5-dihydroxycinnamic acid, methyl 4-hydroxy cinnamate and robustol and three minor related macrocyclic phenols in leaves [2] A thorough re-investigation of Grevillea robusta wood has now revealed the presence of three new phenolic components. Two of them, mono-norstriatol and bis-norstriatol, have been assigned structures as 1-(3,5-dihydroxyphenyl), 14-(3,5-dihydroxy 4-methyl-phenyl)-tetradecane (1a) and 1,14-bis-(3,5-dihydroxyphenyl) tetradecane (1b) respectively based on spectraldata. The UV and IR spectra showed them to be phenolic in nature and PMR and mass spectral comparison with striatol (1c) [3] indicated them to lack one and two C-methyl groups respectively. Although the methyl ether of the latter is known as a synthetic product [3], this is the first report of its natural occurrence; the former is an entirely new natural product.The occurrence of compounds with the diphenyltetradecane skeleton in G. robusta is of interest, the only member of this class till now being striatol from the wood of G. striata. The two compounds are also of biogenetic interest, mono-norstriatol being a possible intermediate in the elaboration of striatol [4]. Toddalia aculeata was collected and supplied by Mukerjee & Co., Algarah, Darjeeling, India and is widely distributed in subtropical Himalayas, Southern India and Ceylon. The plant is used in medicine as a tonic, stimulant, and antipyretic.The plant has been extensively investigated and a number of coumarins and alkaloids have beenreported [1,2]. From the chloroform extract of the stem two new coumarins, norbraylin (1) and 5.7.8-trimethoxycoumarin have been isolated. In addition 3 alkaloids, robustine, dictamnine and γ-fagarine, and 2 coumarins, bergapten and luvangetin, have been isolated for the first time from this plant.
