Two new tirucallane triterpenoids, aquilacallanes A-B (1-2), together with 15 known compounds (3-17) were isolated from the leaves of Aquilaria sinensis. The structures of these new compounds were elucidated on the basis of extensive spectroscopic analyses. All compounds were evaluated for their
The therapeutic potential of adiponectin regulation has received interest because of its association with diverse human disease conditions, such as diabetes, obesity, atherosclerosis, and cancer. Phenylethylchromone derivatives from Aquilaria malaccensis-derived agarwood promoted adiponectin
The tree Aquilaria malaccensis is a valuable source of agarwood, which is used in herbal medicinal preparations. Phytochemical research on A. malaccensis seeds has led to the isolation of four new phorbol esters (1-4), two known phorbol esters (5, isolated from Nature for the first time, and 6), and
A new chromone, 2-(2-hydroxy-2-phenylethyl)chromone (1), was isolated together with ten known phenylethyl chromones from MeOH extracts of agarwood (Aquilaria filaria). The selected compounds were evaluated in an antiproliferative assay against five human tumor cell lines, including a
A novel degraded sesquiterpene, named aquilarin B (1), together with two known compounds (2 and 3), was isolated from the EtOH extract of the fresh stem of Aquilaria sinensis (Lour.) Gilg. Their structures were elucidated by spectroscopic methods including 1D and 2D NMR (HMQC, (1)H-(1)H COSY, HMBC,
Seven new 2-(2-phenylethyl)chromone derivatives (1-7) including a chlorinated one (4), together with eight known ones (8-15), were isolated from the EtOAc extract of artificial agarwood originating from Aquilaria sinensis (Lour.) Gilg. All structures including the absolute configurations were
OBJECTIVE
To study the volatile constituents from peel of Aquilaria sinensis (Lour.) Gilg. and its anti-tumor activity.
METHODS
The volatile components from peel of A. sinensis were extracted by chloroform and analysed by the GC-MS technique. Assay the peel extract of A. sinensis on MCF-7 cell
OBJECTIVE
To investigate the chemical constituents of an endophytic fungus, Nodulisporium sp. A4, from the medicinal plant Aquilaria sinensis and search for antitumor natural products.
METHODS
The fungus was cultured in liquid medium and extracted with EtOAc. The compounds were isolated by various
BACKGROUND
Agarwood is derived from Aquilaria trees, the trade of which has come under strict control with a listing in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Many secondary metabolites of agarwood are known to have medicinal value to
The purpose of this study was to isolate and characterize endophytic fungi from the stem tissue which can produce fragrant ingredients in Aquilaria sinensis (also called agarwood) to determine their antitumor and antimicrobial activities. Twenty-eight fungal endophytes were isolated from agarwood by
Two new cyclohexene derivatives colletotricones A and B (1 and 2) and a new thiazole derivative colletotricole A (5), along with six known natural metabolites were isolated from the extract of Colletotrichum gloeosporioides A12, an endophytic fungus derived from Aquilaria sinensis. Among them, the
BACKGROUND
Aquilaria crassna has been used in traditional Asian medicine to treat vomiting, rheumatism, asthma, and cough. Furthermore, earlier studies from our laboratory have revealed that the essential oil extract from agarwood inhibited colorectal carcinoma cells. Despite of the wide range of
BACKGROUND
Aquilaria spp. (agarwood) has been a part of Ayurvedic and Traditional Chinese Medicine for centuries. Agarwood has also been used as a traditional medicine in Southeast Asian countries, Bangladesh and Tibet. Its common uses include the treatment of joint pain, inflammatory-related
Background
Cyclophosphamide (CP) is a widely used anti-neoplastic and immunosuppressive agent that is associated with adverse side effects including reproductive toxicity.
Aquilaria malaccensis (AM) is a traditional medicinal plant which was reported to exhibit high
The present study reports a bioassay-guided isolation of β-caryophyllene from the essential oil of Aquilaria crassna. The structure of β-caryophyllene was confirmed using FT-IR, NMR and MS. The antimicrobial effect of β-caryophyllene was examined using human pathogenic bacterial and fungal strains.
