    Study Notes

    Microscopy of Eucalyptus Leaf

    • Eucalyptus leaves are used to extract oil and leaves, which have various uses:
      • As an antiseptic
      • As a febrifuge to reduce fever
      • As an expectorant, particularly beneficial for smokers

    Buchu Leaf

    • Buchu leaves come from the Barosma betulina plant, belonging to the Rutaceae family
    • Also known as "short Buchu"
    • Characteristics of Buchu leaf:
      • Punctate (dotted with minute pits or translucent dots) when viewed against light due to scattered oil glands
      • Size of leaflets
      • Presence of impressions on the lamina due to the midrib of other leaflets (package effect)
      • Stomatal index
      • Vein-islet number

    Chemical Test for Buchu Leaf

    • Separate ether or benzene into a clean test tube and shake with 2 ml of dilute NH4OH solution
    • A rose-red to intense red color (but not yellow) is produced, which distinguishes it from Cassia Dr.

    Senna Leaflets

    • Origin: Senna leaves are the dried leaflets of Cassia acutifolia (Alexandrian or Khartoum senna) and Cassia angustifolia (Tinnevelly or Indian senna)
    • Family: Leguminosae (Fabaceae)
    • To differentiate between Alexandrian senna and Indian senna, examine:
