Two new resveratrol tetramers, hopeaphenol A (1) and isohopeaphenol A (2), along with the known vaticaphenol A (3), were isolated from the stem bark of Vatica oblongifolia ssp. oblongifolia through bioassay-guided fractionation. The structures and their relative stereochemistry were determined by spectroscopic techniques. Compounds 1 and 3 demonstrated moderate activity against methicillin-resistant Staphylococcus aureus and Mycobacterium smegmatis. 

Chemical constituents in the leaves of Vateria indica.

Comprehensive re-investigation of the chemical constituents in the leaves of Vateria indica (Dipterocarpaceae) resulted in the isolation of a novel resveratrol dimeric dimer having a C(2)-symmetric

Biologically active oligostilbenes from the stems of Vatica mangachapoi and chemotaxonomic significance

Phytochemical investigation of the stems of Vatica mangachapoi led to the isolation and structural elucidation of twenty-seven oligostilbenes, including a new natural compound 1, which was first time determined by a combination of NOESY spectrum and quantum chemical computation.

Cytotoxic Activity of Secondary Metabolites from the Bark of Dipterocarpus Confertus Sloot

Four compounds, namely β-sitosterol (1), betulinic acid (2), cinnamic acid (3), and α-viniferin (4) have been successfully isolated from the bark methanol extract of Dipterocarpus confertus Sloot.

Oligostilbenes from Vatica mangachapoi with xanthine oxidase and acetylcholinesterase inhibitory activities

Phytochemical examination of the branches and twigs of the tropical plant Vatica mangachapoi resulted in the isolation of three novel oligostilbenes named vaticahainols A–C (1–3) along with seventeen

Stilbenoids from Hopea acuminata

Two resveratrol oligomers were isolated from the ethyl acetate extracts of the leaves of Hopea acuminata and were found to inhibit protein splicing mediated by the Mycobacterium tuberculosis RecA intein in a nonspecific manner.

Hopeanolin and other Resveratrol Oligomers from the Twigs of Shorea acuminata: Antioxidant Propertiaes and Chemotaxonomic Significance

The presence of compound 1 and the other four resveratrol oligomers in this species have great chemotaxonomic significance on the relationship between Shorea and other genera of Dipterocarpaceae especially Hopea.

New Resveratrol Tetramers from the Stem Bark of Upuna borneensis

Five new resveratrol tetramers were isolated from the stem of Upuna borneensis and their structures were elucidated on the basis of 1D‐ and 2D‐NMR as well as FAB‐MS data.

Antimicrobial and Cytotoxic Activities of the Crude Extracts of Hopea scaphula

A very tall tree which grows in Chittagong and the neighboring HillTracts areas of Bangladesh and is reported to have anititumor, cytotoxic, anti-HIV, astringent, CNS depressant, hypotensive and antifungal properties.

Oligostilbenoids with Acetylcholinesterase Inhibitory Activity from Dipterocarpus alatus

The discovery of compound 3 gave the first evidence that the biosynthetic origin of resveratrol aneuploids is related to the loss of a half resver atrol unit by oxidative cleavage.
