title: [Two new phragmalin-type limonoid orthesters from Chukrasia tabularis var. velutina].
abstract: As a part of our ongoing research program to isolate novel phragmalin limonoids from the stem bark of Chukrasia tabularis var. velutina, two new phragmalin limonoids orthesters, tabularin Q (1) and tabulalide O (4), along with two known compounds tabularin C (2) and tabularin H (3) were isolated. Their structures were elucidated by means of extensive 1D and 2D spectroscopic analyses which included HSQC, HMBC, and ROESY experiments and HR-ESI-MS.
