The stem bark of the Thai tree Aquilaria malaccensis (Thymelaeaceae) has afforded 1,3-dibehenyl-2-ferulyl glyceride (3), which is novel, and 12-O-n-deca- 2, 4, 6-trienoylphorbol-13-acetate (4). The structures of these cytotoxic compounds were elucidated by their spectral and chemical parameters.
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
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
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
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
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 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.
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
BACKGROUND
Agarwood is a priceless non-timber forest product from Aquilaria species belonging to the Thymelaeaceae family. As a result of a defence mechanism to fend off pathogens, Aquilaria species develop agarwood or resin which can be used for incense, perfumery, and traditional medicines.
Two new chromone derivatives, 7-hydroxy-2-[2-(3'-methoxy-4'-hydroxyphenyl)-ethyl]chromone (1), and 6,7-dimethoxy-2-[2-(3'-hydroxyphenyl)-ethyl]chromone (2) were isolated from the EtOH extract of agarwood of Aquilaria sinensis, together with eleven known analogues. Their structures were established
Medicinal plants played an important role in traditional medicine for the treatment of diseases since antiquities. The aim of the study is to carry out an ethnobotanical survey on medicinal plants used traditionally in cancer treatment in the region of Greater Casablanca-Morocco, and to enhance the
