Triterpenoids, lignans and a benzofuran derivative from the bark of Aglaia elaeagnoidea

Diamide Derivatives and Cycloartanes from the Leaves of Aglaia elliptica.

“…The EI-, FAB-, and HR-EI-MS were recorded on JEOL JMS-DX 300 and JMS-700T spectrometers. The 1 H-and 13 C-NMR spectra were recorded on a GE-OMEGA 600 spectrometer (600 and 150 MHz, respectively), with MeOH-d 4 as a solvent and tetramethylsilane (TMS) as an internal standard. HPLC was performed on a JAILC-908 instrument with JAIGEL-ODS-S343-15 and JAIGEL-GS310 columns with a differential refractometer.…”

“…Several novel amides containing a cyclopenta-[bc]benzopyran moiety (ϭaglain-type) and a cyclopenta- [b]benzofuran moiety (ϭrocaglamide-type) as the acid part have been characterized from this genus, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] some of which were shown to exhibit cytotoxic 1,3,5,7,10,19,20) insecticidal, 2,6,8,9,[11][12][13][14][15]17) and antifungal 4) activities. In our series of studies of this genus, 16) we have investigated the constituents of the leaves of Aglaia elliptica Bl.…”

Genetic diversity and geographic structure in Aglaia elaeagnoidea (Meliaceae, Sapindales), a morphologically complex tree species, near the two extremes of its distribution

“…Additionally, the Australian samples were characterized by the formation of a triterpene derived limonoid, 6-α-acetoxygedunin (Hofer 2002). Although widespread in the Meliaceae, limonoids are apparently rare in Aglaia, only described so far for another collection of A. elaeagnoidea from Sempu Island (Java) also containing the flavagline aglafoline with a dimethoxylated ring A (Fuzzati et al 1996). The accumulation of different bisamides represents another important chemical character distinguishing the Australian samples from the Western Group.…”

Two Novel abeo‐Dammaranes with a Six‐Membered Acetal Moiety from Aglaia perviridisHiern

“…-The genus Aglaia of the family Meliaceae has attracted considerable interest as a possible new source of unique natural products for integrated pest management. In the past decades, many novel compounds such as bis-amides, lignans, and triterpenes have been isolated from this genus [1]. Nevertheless, as a part of our work, we continued our search for novel constituents in the genus Aglaia …”

“…The CHCl 3 -soluble material of an EtOH extract of the twigs of Aglaia perviridis Hiern, which mainly distributed in South China and India [5], gave two abeo-dammaranes with a novel six-membered cyclic acetal moiety, (20S,24S)-20,24-epoxy-24-methoxy-23(24 ! 25)abeo-dammaran-3-one (1), and (3a,20S,24S)-20,24-epoxy-24-methoxy-23(24 ! 25)abeo-dammaran-3-ol acetate (2).…”
