    Euphorbia factor L2 induces apoptosis in A549 cells through the mitochondrial pathway.[Pubmed: 28119809 ]
    Euphorbia factor L2, a lathyrane diterpenoid isolated from caper euphorbia seed (the seeds of Euphorbia lathyris L.), has been traditionally applied to treat cancer. This article focuses on the cytotoxic activity of Euphorbia factor L2 against lung carcinoma A549 cells and the mechanism by which apoptosis is induced.
    We analyzed the cytotoxicity and related mechanism of Euphorbia factor L2 with an MTT assay, an annexin V-FITC/PI test, a colorimetric assay, and immunoblotting. Euphorbia factor L2 showed potent cytotoxicity to A549 cells. Euphorbia factor L2 led to an increase in reactive oxygen species (ROS) generation, a loss of mitochondrial electrochemical potential, release of cytochrome c, activation of caspase-9 and caspase-3, and cleavage of poly(ADP-ribose) polymerase, suggesting that Euphorbia factor L2 induced apoptosis through a mitochondrial pathway.
    The cytotoxic activity of Euphorbia factor L2 in A549 cells and the related mechanisms of apoptotic induction provide support for the further investigation of caper euphorbia seeds.

    A sensitive liquid chromatography–mass spectrometry method for simultaneous determination of three diterpenoid esters from Euphorbia lathyris L. in rat plasma.[Reference: WebLink]
    A selective and sensitive liquid chromatography–mass spectrometry (LC–MS) method was developed for the simultaneous determination of Euphorbia factor L1, Euphorbia factor L2 and Euphorbia factor L3 from Euphorbiae semen in rat plasma.
    Larotaxel was added to a 200 μL plasma sample as the internal standard (IS). The plasma sample was extracted by 2 mL ether and separated on an Elite C18 column (150 mm × 4.6 mm, 5 μm) with the mobile phase of methanol–water performing gradient elution within 11.0 min. All the three analytes were detected in the selected ion monitoring (SIM) mode with positive electrospray ionization. The calibration curves were linear in the range of 2.0–200 ng/mL and the lower limits of quantification (LLOQ) were 2.0 ng/mL for all the three analytes. The intra-day and inter-day precisions were all within 8.6% and 14.6% for the three analytes, while the accuracy was less than 9.7% and 7.5%, respectively.
    The validated method was firstly and successfully applied to the pharmacokinetic study of Euphorbia factor L1, Euphorbia factor L2 and Euphorbia factor L3 from Euphorbiae semen after oral administration in rat plasma.
