Partially purified mushroom exudates induce apoptosis in acute promyelocytic leukemia cell line (HL-60)
Mycelial exudates of Lentinula edodes 1358 strain were observed to be produce profusely among other strains. They were collected, partially purified and evaluated for their antiproliferation activity on acute promyelocytic leukemia cells (HL-60). The partially purified fraction 8 prepared by preparative HPLC using 1% acetic acid and methanol had the strongest Inhibition concentration (IC50) values at 21.59...

Comparison of the antimicrobial activity and essential oil content of wild and micropropagated Origanum sipyleum L.: A medicinal herb native to Turkey
Water-distilled essential oils of wild and micropropagated Origanum sipyleum L. (Lamiaceae), a herb native to Turkey, were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). Eighteen components were characterized. In wild plants, the major constituent of aerial parts was α-cadinol (23.41%), and of flowers, germacrene-D (20.13%). Thymol (48.55%)...

Simultaneous determination of three active constituents in Erigeron breviscapus by high-performance liquid chromatography
A rapid, simple and reliable high-performance liquid chromatographic (HPLC) method was developed for simultaneous determination of compound 1 (scutellarin), compound 2 [1,5-dicaffeoylquinic acid (1,5-DQA)] and compound 3 [1,3-dicaffeoylquinic acid (1,3-DQA)] inErigeron breviscapus. The three constituents were measured on a Zorbax XDB-C18column (4.6 mm × 150 mm, 5 μm) with a gradient elution of acetonitrile...
