  2. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Thin-layer chromatography is used to separate components of a plant extract, illustrating the experiment with plant pigments which gave chromatography its name. In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components.

  4. Column chromatography - Wikipedia

    en.wikipedia.org/wiki/Column_chromatography

    Column chromatography in chemistry is a chromatography method used to isolate a single chemical compound from a mixture. Chromatography is able to separate substances based on differential absorption of compounds to the adsorbent; compounds move through the column at different rates, allowing them to be separated into fractions.

  5. Cnidoscolus aconitifolius - Wikipedia

    en.wikipedia.org/wiki/Cnidoscolus_aconitifolius

    The specific epithet, aconitifolius, refers to the plant’s "Aconitum-like leaves"—coincidentally, another well-known dangerous, even deadly, genus of plants. As with most euphorbias , the entire plant contains a caustic, viscous and potentially dangerous white sap which flows readily when any part of the plant is broken, cut or damaged.

  7. Spinacia - Wikipedia

    en.wikipedia.org/wiki/Spinacia

    Plants are always glabrous. Their stems grow erect and are unbranched or sparsely branched. The alternate leaves consist of a petiole and a simple blade. The basal leaves are often forming a rosette. The leaf blade is triangular-hastate to ovate, sometimes with elongated lobes, with entire or dentate margins and an acute apex. [1] [2]

  8. Mikhail Tsvet - Wikipedia

    en.wikipedia.org/wiki/Mikhail_Tsvet

    Mikhail Tsvet invented chromatography in 1900 during his research on plant pigments. He used liquid-adsorption column chromatography with calcium carbonate as adsorbent and petrol ether/ethanol mixtures as eluent to separate chlorophylls and carotenoids. The method was described on 30 December 1901 at the XI Congress of Naturalists and ...

  9. Tetragonia decumbens - Wikipedia

    en.wikipedia.org/wiki/Tetragonia_decumbens

    The plant is edible and is a local delicacy in its native southern Africa, where it is known as "dune spinach". It is an important component of dune vegetation, being a hardy pioneer and stabilising dunes. The organic material it produces prepares the way for ensuing plants.
