Phragmalin Limonoids from the Stem Barks of Chukrasia tabularis var. velutina

Planta Medica, 2014
Seven new phragmalin limonoids, chukvelutilides I-O (1-7), were isolated from the stem barks of Chukrasia tabularis var. velutina. Their structures were elucidated by extensive spectroscopic analysis. Among them, compound 1 showed moderate lethal activity against brine shrimp larvae, with an LC50 value of 84.1 µM.

First report of Tapinolachnus lacordairei (Coleoptera: Cerambycidae) damage in Chukrasia tabularis

International Journal of Tropical Insect Science, 2020
Chukrasia tabularis (Meliaceae) has been planted for many decades in home gardens and plantations in Vietnam. Recently, growers have become concerned with attack by stem borers. Tapinolachnus lacordairei J. Thomson 1864 (Coleoptera: Cerambycidae) is identified as a new indigenous pest causing damage to 15 to 30 year-old stands of C.

Phytochemical and antimicrobial study of Chukrasia tabularis leaves

Fitoterapia, 2001
Successive petroleum ether, benzene, chloroform, ethyl acetate and methanol extracts of Chukrasia tabularis leaves were tested for their phytochemical constituents, antibacterial and antifungal activity. The ethyl acetate and methanol extracts were found to be most effective against most of the tested organisms.

Kv1.2 potassium channel inhibitors from Chukrasia tabularis

Organic & Biomolecular Chemistry, 2012
Eighteen new limonoids, chubularisins A-R (1-18), along with eleven known analogues, were isolated from the stem bark of Chukrasia tabularis. The structures of 1-18 were elucidated on the basis of spectroscopic data and chemical evidence. Compound 1 represented the first example of 8,9,12-orthoester of phragmalin limonoids.

Chukrasia tabularis - An oil-yielding tree

Journal of Non-Timber Forest Products, 1997
Seeds of Chukrasia tabularis contain 30% of oil which is quite encouraging. The oil is rich in linoleic and linolenic acids which are nutritionally essential fatty acids. The oil does not contain oxygenated fatty acid glyc­erides and epoxy fatty acid glycerides, hence the oil is likely to be a good edible oil provided it has no toxic properties.

Limonoids from the Twigs and Leaves of Chukrasia tabularis

Helvetica Chimica Acta, 2008
AbstractSeven new limonoids, tabularisins J–P (1–7, resp.), together with eight known compounds, were isolated from the twigs and leaves of Chukrasia tabularis. Their structures were determined primarily by spectroscopic methods. The potassium channel blocking activities of some of these isolates were evaluated, and a few of them exerted significant ...
