One new phenolic glycoside, methyl 3,4-dihydroxyphenylacetate-4-O-[2-O-β-D-apisoyl-6-O-(2-hydroxybenzoyl)]-β-D-glucopyranoside (1), together with 10 known compounds (2-11), were isolated from the roots of Datura metel. The structures of these

Nine new (1-9) and three known (10-12) sesquiterpenoids were isolated from the ethanol-water (7:3, v/v) extract of the Datura metel L. leaves. The structures of 1-9 were elucidated by detailed spectroscopic analyses, including 1D and 2D NMR, HR-ESI-MS. All isolates (1-12) were evaluated for

A new sesquiterpenoid glycoside, consisting of one vetispirane-type, dmetelisproside A (1), together with two known megastigmane sesquiterpenoids, citroside A (2) and staphylionoside D (3) were isolated from the leaves of Datura metel L. The structures were determined by analysis of their MS and NMR

Nine new withanolides, named daturafolisides A-I (1-9), along with six known compounds (22R)-27-hydroxy-7α-methoxy-1-oxowitha-3,5,24-trienolide-27-O-β-d-glucopyranoside, daturataturin A, daturametelin J, daturataurin B, baimantuoluoside B, 12-deoxywithastramonolide (10-15), were isolated from the

Twenty three undescribed withanolides, daturmetelides A-W (1-23), were isolated from 70% EtOH extract of the leaves of Datura metel L. The structural characterizations and relative configurations of 1-23 were elucidated by extensive spectroscopic analysis as well as by comparison with literature

Psoriasis is an immune-mediated inflammatory dermatosis characterized by epidermal hyperplasia and excessive infiltration of inflammatory cells. Withanolides, extracted from Datura metel L.; are the main effective components for the treatment of psoriasis. However, the precise mechanisms of

Datura metel L. (Solanaceae) is an annual herb that has been widely used in the traditional medicine for the treatment of coughs, bronchial asthma, and rheumatism. Chemical investigation of an acidic methanol extract of the whole plants of D. metel resulted in the isolation of five new steroidal

Five undescribed ergostane-type C₂₈ sterols, daturmetesides A-E (1-5), were isolated from the leaves of Datura metel L. The chemical structures of these new compounds were characterized through extensive spectroscopic analysis and comparison with literatures. Among them, the absolute

The current study deals with the investigation of the antioxidant, anti-inflammatory and immunomodulatory properties of the essential oil from Datura stramonium leaves (D. oil). The GC-MS analysis showed that the dominant compounds present in the D. oil were neophytadiene (Phytol acetate)

Psoriasis is a chronic, immune-mediated inflammatory skin disease, and the inflammatory response plays an important role in its development and progression. Datura metel L. is a traditional Chinese medicine that exhibited a significant therapeutic effect on
