Six acetophenone derivatives, acronyculatins I (1), J (2), K (3), L (4), N (5), and O (6), were recently isolated from Acronychia trifoliolata, and the structure of the known acronyculatin B (7) was revised. Because of the limited quantities of isolated products as well as their structure
From the roots of Acronychia pedunculata (L.) Miq. (Rutaceae) collected in Taiwan, six known and three new acetophenones have been isolated. The new compounds were named acrophenones D (1), E (2), and F (3). Of the acetophenones isolated in this study, prenylacronylin (4) and acronyculatin D. (10)
Seven new [acronyculatins I-O (1-7)] and four known acetophenone monomers were isolated from a CH3OH/CH2Cl2 (1:1) extract (N089419) of Acronychia trifoliolata provided by the U.S. National Cancer Institute (NCI, Frederick, MD, USA). Their structures were characterized by using various NMR and HRMS
Phytochemical investigation of the leaves and twigs of Acronychia pedunculata has led to the isolation of three new acetophenone monomers 1-3 as well as 1-[2',4'-dihydroxy-3',5'-di-(3″-methyl-2″-butenyl)-6'-methoxy]phenylethanone (4), acronyculatin E (5), a mixture of β-sitosterol and stigmasterol,
Bioassay-directed fractionation of a root extract of Acronychia laurifolia (Rutaceae) using the KB-V1+ human tumor cell line led to the isolation of six quinoline alkaloids. One of these alkaloids is novel, namely, 2,3-methylenedioxy-4,7-dimethoxyquinoline and the other five were identified as the
Three new acetophenone dimers or Acronychia-type acetophenones, acropyrone (1), acropyranol A (2), and acropyranol B (3), were isolated from the trunk bark of Acronychia pedunculata and structurally characterized, together with four known acetophenone dimers, acrovestone (4), acrovestenol (5),
The genus Acronychia (Rutaceae) comprise 44 species, most of which are represented by shrubs and small trees, distributed in a wide geographical area of South-Eastern Asia comprising China, India, Malaysia, Indonesia, Australia, and the islands of the western Pacific Ocean. Most of the species of
Study plots totaling 0.2 Ha were established in primary forest in the highlands of central Palawan Island, Philippines. Samples of various anatomical parts [typically leaf + twig (If/tw), stem bark (sb), and root (rt)] were collected from all tree species represented within the plots by individuals
