Direct hyphenation of analytical-scale high-performance liquid chromatography, photo-diode array detection, mass spectrometry, solid-phase extraction and nuclear magnetic resonance spectroscopy (HPLC-PDA-MS-SPE-NMR) has been used for accelerated dereplication of crude extract of Haplophyllum acutifolium (syn. Haplophyllum perforatum). This technique allowed fast on-line identification of six qu...
during the past decade, natural plant products as environmentally safe option have received attention for controlling phytopathogenic diseases. investigation of plants containing natural antimicrobial metabolites for plant protection has been recognized as a desirable method of disease control. the fungus fusarium oxysporum causes diseases such as root rot, damping off and fusarium wilt and it ...
Two new lignan glycosides of dibenzylbutyrolactol type (haplomarin) and arylnaphthalene type (haploborin) were isolated from the aerial parts of Haplophyllumn suaveolens together with the known arylnaphthalene lignan glycoside arabelline and hydroxycoumarin glycoside xeroboside. So far arabelline is found only in H. buxbaunii. This is the first report of the isolation of xeroboside from Haploph...
The aerial parts of H. perforatum subsp. perforatum and H. perforatum subsp. angustifolium were investigated for their chemical composition and antimicrobial activity. Spectrophotometric analysis indicated that H. perforatum subsp. perforatum is richer in flavonoids and tannins than the other subspecies. HPLC analysis confirmed the higher yield of flavonoids in H. perforatum subsp. perforatum a...
The volatile components of the aerial parts of Ruta graveolens and Haplophyllum suaveolens, as well as of leaves of Zanthoxylum limoncello, Z. panamense and Z. setulosum have been studied by GC/MS analysis.
Observations: Hypericin, originating from Hypericum perforatum, is a potent photosensitizer known to induce skin phototoxicity when given systemically. Hypericum perforatum is a botanical extracts with anti-inflammatory and antibacterial effect. Photocontact dermatitis is a common cutaneous reaction by various herbs. We describe a 54-year-old female patient with Hypericum perforatum associated ...
