Morphological and anatomical research of herbs and root tubers stachys Siebold (Stachys sieboldii Miq.)
Stachys Siebold (Stachys Sieboldii Miq.) – is а perennial herb of the family Lamiaceae, culture is grown as an annual.
Stahis used in Chinese and Tibetan folk medicine for the treatment of tuberculosis , hypertension and as a sedative . Biologically active agents contained in tubers affect carbohydrate and lipid metabolism, reduce blood pressure, blood cholesterol.
To determine main diagnostic characters of the crude drugs morphological and anatomical investigation of stachys Siebold herbs and root tubers.
Microscopic analysis was performed using a microscope MBR-1 is the IBI-6 LOMO. Photomicrography made by camera D-580 ZOOM/ C-460 ZOOM/ X-400.
Stems quadrangular, covered with long hairs, hollow inside. Leaves opposite, short, omitted from the upper and lower surfaces, integral, oval-ovate, coarsely toothed margins. The flowers are collected in 4‒5 rare whorls, which are combined in long spike-like inflorescences.
Tubers oblong, with successive bulges and constrictions, ivory, pearl shimmer.
It was established that the main anatomic diagnostic features of stachys Siebold tubers is a well-developed parenchyma, stock up the carbohydrates, which is dominated by tetrasaccharide stachyose, primary cortex is separated from the central cylinder with large expressive endoderm, with thickened walls cells and yellowish-brown contents. The upper leaf epidermis with stomata diacytic type, lots of trichomes. Upper epidermis cells are thin, with winding, undulating side walls; lower epidermis with numerous stomata, simple 2‒4-cell extended hairs, with thickened walls, with glandular trichomes and essential oil glands. The epidermis of the stem with trichomes identical sheet, the basic cells of the epidermis ribs narrow, simple hairs long, sharp, with thickened basal cell. Calyx with five sharp-pointed teeth, thin veins, pubescent specific glandular hairs with a long, two-cell thin stalks, multicellular raised rosette and two-cell layered head with a yellow secret. The cells of the epidermis of the corolla tube narrow, oblong, with few hairs.
As a result of the macro and microscopic analysis were established basic diagnostic morphological and anatomical features of stachys Siebold herbs and root tubers, which will be used to identify new drug raw materials.
