Three Libyan Salvia species were subjected to comprehensive study of
microscopic characteristics of trichomes and biological activities of their extracts, while
the selected species have not been studied previously.
The micromorphology, ultrastructure and histochemistry of S. aegyptiaca, S.
fruticosa and S. lanigera leaf trichomes were investigated using light, scanning and
transmission electron microscopy. The leaves bear abundant unbranched non-glandular
and two types of glandular trichomes - peltate and capitate, on both leaf surfaces. Since
Salvia species are used for medicinal and cosmetic purposes, due to essential oils
secreted in the glandular trichomes, the focus was on the analyses of the glandular
trichomes.
In S. aegyptiaca leaves the peltate trichomes were composed of basal cell, short
cylindrical stalk cell and broad head of eight to twelve secretory cells arranged in a
single circle, or more in two circles. Capitate trichomes (hairs) consisted of one-celled
glandular hea...d, subtended by a stalk of variable length, and classified into two types:
capitate type I or short-stalked capitate and capitate type II or long-stalked capitate
trichomes. Histochemical tests showed that the secreted material in all types of S.
aegyptiaca glandular trichomes was of a complex nature. Positive reactions to lipids for
all types of glandular trichomes were obtained, with especially abundant secretion
observed in peltate and capitate trichomes type II.
In S. fruticosa peltate hairs consisted of basal epidermal cell, very short stalk cell
and large round head of eight secretory cells arranged in a circle. Capitate trichomes can
be divided into two main types, short stalked and long stalked, and further into five
subtypes according to the number of stalk cells, the morphology and the number of the
glandular head cells. Digitiform trichomes consisted of one basal cell, one or two stalk
cells and one apical secretory cell, which are of similar diameter and approximately
equal length...
