Enhancers of Agrobacterium-mediated Transformation of Tibouchina semidecandra Selected on the Basis of GFP Expression.

Trop Life Sci Res 2010 Dec;21(2):115-30

Department of Microbiology, Universiti Putra Malaysia, 43400 UPM Serdang, Selangor, Malaysia.

Genetic engineering is a powerful tool for the improvement of plant traits. Despite reported successes in the plant kingdom, this technology has barely scratched the surface of the Melastomataceae family. Limited studies have led to some optimisation of parameters known to affect the transformation efficiency of these plants. Read More

Isolation and identification of radical scavenging and tyrosinase inhibition of polyphenols from Tibouchina semidecandra L.

J Agric Food Chem 2010 Oct;58(19):10404-9

Department of Chemistry, Faculty of Science, Universiti Teknologi Malaysia, 81310 Skudai, Johor, Malaysia.

Phytochemical and bioactivity studies of the leaves and stem barks of Tibouchina semidecandra L. have been carried out. The ethyl acetate extract of the leaves yielded four flavonoid compounds, identified as quercetin, quercetin 3-O-α-l-(2''-O-acetyl) arabinofuranoside, avicularin, and quercitrin, while the stem barks gave one ellagitannin, identified as 3,3'-O-dimethyl ellagic acid 4-O-α-l-rhamnopyranoside.

Tannins and related polyphenols of melastomataceous plants. VIII. Nobotanins L, M and N, trimeric hydrolyzable tannins from Tibouchina semidecandra.

Chem Pharm Bull (Tokyo) 1999 Jun;47(6):824-7

Faculty of Pharmaceutical Sciences, Okayama University, Tsushima, Japan.

Three hydrolyzable tannins, nobotannins L, M and N, were isolated from the water-soluble portion of the leaf extract of Tibouchina semidecandra, and their trimeric structures were elucidated from spectral and chemical evidence. Nobotanins L and N exist as equilibrium mixtures of four anomers due to the presence of two unacylated anomeric centers. Read More
