Sesquiterpenoids, an important class of natural products possessing three isoprene-derived
units, are widely distributed across plants and have a variety of biological activities. All …

Abstract Aquilaria sinensis (Lour.) Spreng.(Thymelaeaceae family), is the fragrant resin-
infused wood derived from the wounded trees of Aquilaria species. With years of studies …

The n-hexane fraction from the stem bark of Lansium domesticum Corr. Cv. Kokosan
afforded 3 sesquiterpenoids, namely eudesm-4 (15), 7-dien-1β-ol (1), eudesm-4 (15)-ene …

Three new sesquiterpene phenol dimers, bidysoxyphenols A–C (2–4), along with two known
compounds, namely sesquiterpene phenol (1) and ionone derivatives (5), were isolated …

A new phenolic sesquiterpene, dysoxyphenol (1), and the known sesquiterpene, 7R, 10S-2-
hydroxycalamenene (2), were isolated from the acetone extract of Dysoxylum densiflorum …

Three new bisindole alkaloids, bisleuconothines B–D (1–3), were isolated from the bark of
Leuconotis griffithii. Their structures were elucidated by 1D and 2D NMR spectroscopy and …

Eight new limonoids, walsogynes H–O (1–8) were isolated from the barks of Walsura
chrysogyne, and their structures were determined on the basis of the 1D and 2D NMR data …

A new bicoumarin derivative, bidysoxyletine (B 1 b), was isolated from the leaves of I
Dysoxylum parasiticum i (Osbeck) Kosterm. The ultraviolet (UV) spectrum showed four …

Bioactivity guided separation of Reinwardtiodendron cinereum barks methanol extract led to
the isolation of two new onocerane triterpenoids, reinereins A and B (1 and 2), together with …

This paper reports the chemical isolation and antibacterial properties of terpenoid
components of Dysoxylum densiflorum. Three new tetracyclic triterpenoic acids, densiflorinic …
