Abstract: ObjectiveTo conduct pharmacognosical studies on the roots and leaves of Allamanda cathartica L. and Lantana
camara L. for the purpose of offering references to their clinical use, rescuing poisoned persons, development and usage. MethodsThe plants' characters and their microscopic
structures, as well as their physicochemical properties were studied. ResultsPhellem in horizontal sections of Allamanda cathartica L. was thick, clearly consisting of two layers; and many starch grains and crystal clusters of calcium oxalate were found in the cross sections of its stems and its powder. Structures of cells of rays in the horizontal sections of
Lantana camara L. were relatively exceptional; sclerenchymae was discovered in the square cross sections of its stems; its powder possessed unicellular non-glandular hairs, in which
secretory cells containing orange oil drops were found.
ConclusionThe result can be taken as the basis for the identification of the two plants.
Key words: Allamanda cathartica L.; Lantana camara L.; Pharmacognosy
In the commonly used medicinal plants, some are poisonous. In clinical and non-governmental applications, due
to inadvertent or misuse of medication and other reasons caused cases of poisoning and even death have occurred. Allamanda cathartica Apocynaceae plants for Allamanda cathartica Allemanda cathartica L., whole-plant medicine,
diarrhea dredge stasis, for they secretion. Whole-plant toxic,
poisoning people and livestock stolen goods to stimulate the heart, circulatory and respiratory disorder, pregnancy, eating animals, after causing a miscarriage . Lantana camara Lantana camara L. Verbenaceae of plants, roots heat Xiehuo, detoxification Sanjie. Indications cold fever, wounds summer headache, stomach fire toothache, sore throat, mumps, rheumatism Bi Tong, M. scrofulaceum sputum nuclear. Tender leaves Qingrejiedu, Qufeng itching. Attending carbuncle
swollen canker, eczema, scabies, dermatitis, bruises, . Lantana taking large doses can cause poisoning. Poisoning performance: whole body weakness, gait instability, severe diarrhea, after the constipation, the stool for blood with
broken down, so deep and foul color, nose and eye secretions increase, fever, jaundice, and sensitivity to light and can be caused the death . About Allamanda cathartica, lantana on pharmacognosy research have not been reported, the paper Allamanda cathartica, lantana two kinds of poisonous, toxic parts of medicinal plants, pharmacognosy research carried out, together with an organized structure and powder
characteristics of Figure for clinical application, development and utilization of poisoning rescue and provide
Allamanda cathartica medicinal samples from Guangxi Medical College Teaching Weisong Ji, associate professor of medicinal plants collected from the Guangxi College of Physic Garden (cultivated) and identified. Lantana medicine samples from Guangxi Medical Teaching Weisong Ji, associate professor of medicinal plants collected from Nanning, Guangxi, and identify Anji Township, Gan Wei Cun.

Cortex wide, in which the distribution of a large number of starch grains and calcium oxalate crystal clusters. Phloem
narrow, scattered clusters of calcium oxalate crystallization and starch grains. Cambium obvious. Xylem broad, duct large, scattered over a single, radial array. Figure 1.
Stem cross-section surface: epidermal cells, one,
occasionally clusters of calcium oxalate crystallization.
Cortex wide, with clusters of starch grains and calcium oxalate crystallization and trigonal, Victoria tubular sheath part of a fiber, often into bundles. Phloem narrow, circular-
shaped, in which scattered clusters of calcium oxalate
crystallization and starch grains. Cambium obvious. Xylem wide, duct large, multi-radial arrangement of a single,
central a larger hip, thin-walled cells, containing a large
number of starch grains and calcium oxalate crystal clusters. Figure 2. Reposted elsewhere in the paper for free download http://

water threonate (stachyose), Verbascum Sugar (verbascose), Ajuga sugar (ajugose), Mullein 4 Sugar (verbascotetraose), lantana sugar (lantanose) A, B, Thevetia stink ant glycoside A (theveside) and so on. Stems and leaves with lantana ene
(lantadene) A, B, lantana acid (lantanolic acid), lantana different acid (lantic acid), oleanolic acid (oleanolic acid), etc. .
Lantana take root, stem and powder 2 g, plus ethyl ether 10 ml, Zhen Yao dipping 15 min, filtration. Two points to take
the filtrate, 2.5 ml / copies, respectively, placed in the evaporating dish until the ether evaporation, the evaporating dish in a two drops of concentrated sulfuric acid and Canada, significantly dark brown; evaporating dish in another two drops of concentrated hydrochloric acid and Canada, significant light red (color reaction).
This study systematically the above-mentioned two kinds
of poisonous toxic parts of medicinal plants medicinal properties, organizational structure, powder for observation,
experimental results show that Allamanda cathartica phellem root cross-section of a very wide and has two distinct layers; stem Cross-cutting masks pericycle fibers; powder clusters of starch grains and calcium oxalate crystal extremely high.
Lantana camara root cross-section of ray cell structure rather special, stem cross-section of 4 square, and has a thick-
walled tissue; powder in single-cell non-glandular hairs
numerous secretory cells containing orange-yellow oil
droplets. Pharmacognosy characteristics of the above can be used as Allamanda cathartica and lantana basis for the main identification.
