Abstract: ObjectiveTo provide a scientific basis for quality standard of Hibiscus syriacus L..
MethodsPharmacognostic identification was used. ResultsWe described the macroscopic characteristics of the leaves,
powder and microscopic characteristics of Hibiscus syriacus L. ConclusionThe macroscopic and microscopic characteristics can be used for its identification .
Key words: Hibiscus syriacus L.; Leaves; Pharmacognosy
Hibiscus syriacus Hibiscus syriacus L. Malvaceae original plant deciduous shrubs, hibiscus name in the "Erya" already recorded. "Chinese Pharmacopoeia" (1977 edition) will be closed loading H.syriacus L. Althea medicine, and its characteristics and efficacy are introduced. Hibiscus body is
a treasure, hibiscus flowers, fruit, leaves and skin can be used as medicine. Flowers and leaves used as medicine:
Qingreliangxue, detoxification swelling; fruit medicine: Qingfei phlegm, detoxification pain; stem bark, root bark used
as medicine: Qingre Qushi, insecticidal itching.
Lee et al  isolated from Hibiscus Soap grass glycoside (saponarin), yew, Yeh Su-3-O-glucopyranosyl, apigenin 7-O-
glucopyranosyl, and three structures known isoflavone 6 "-O-
acetyldaidzein, 6"-O-acetylgenistin and 3-O-hydroxydaidzein.
These three isoflavones significantly inhibited rat liver microsomal lipid peroxidation. Chao-Yang Li et al  on
hibiscus leaf nutrient composition were determined and found that hibiscus leaves the protein, fat, vitamin C, sugar, crude fiber content higher.
Hibiscus leaves a certain degree of decontamination capabilities, our section of women in ancient times had to use every Qiqiao Hibiscus leaf shampoo habit is a good pure plant shampoo Juju health effects . Hibiscus leaves containing a large number of the human body needs nutrients and inorganic elements. Chao-Yang Li et al  the determination of protein content in hibiscus leaves of up to 3.72%, fat content of up to 0.79%, crude fiber content of up to 9.83%, sugar content of up to 6.27%, but also rich in essential trace elements in the human body, such as calcium, magnesium , iron, zinc and so on. The leaves can also Hibiscus tea soup, with a high medicinal value .
Hibiscus leaves in this experiment will be carried out pharmacognosy research, further research and development and utilization of hibiscus that provide the basis for the rich plant resources.
1.1 herbs hibiscus leaves collected from Forest Park,
Changsha City, Hunan Province Institute for Drug Control Officer by the pharmacist were identified as Fang Shilin Plant hibiscus Hibiscus syriacus L. leaves.
1.2 Instrument XSZ-H-based microscope (COIC, Chongqing
Optical Instrument Factory); FW-80 high-speed universal
grinder (Tianjin Taisite Instrument Co., Ltd.).
1.3 Reagent chloral hydrate, glycerol.
Surface mounted 2.1 tear film will hibiscus leaves from the upper and lower epidermis surface tearing away from the
2.2 Extraction of leaf powder producer of dry herbs crushed into fine powder (over 4 sieve), bottling, labeling. Preparation of powder, attention to sample representativeness. Drying time, generally a temperature not exceeding 60 ?, so
as to avoid gelatinization of starch grains.
2.3 tissue section using free-hand sectioning slice
leaves of the hibiscus cross-section after-loading film.

3.1 Identification of trait-like leaves ovate or oval
Ling, syntrophic, long 4 ~ 7 cm, width 2 ~ 4 cm, do not crack or split the middle and above 3, the base of wedge-shaped, the
edge of a blunt teeth, a small child, sparsely villous on both sides Star -like hair. In addition to hair on dorsal vein, the other smooth and hairless.
3.2.1 upper epidermis of epidermal cells are rectangular or irregular shaped flat cells, containing large clusters of calcium oxalate crystal diameter of 15 ~ 36 μm, containing
calcium oxalate trigonal small diameter of 8 ~ 25 μm. Single-
cell non-glandular base of the blunt round, the top of a little sharp or blunt, long 480 ~ 650 μm, diameter of 15 ~ 33
μm, wall thickness of 3 ~ 8 μm, smooth surface, and some
cell-containing yellow-brown material. Glandular head by a
number of cells, diameter of 12 ~ 23 μm, single-cell and a
short stalk. Occasionally vent, flat-axis, kidney-shaped guard
cells, subsidiary cells 3 to 6. Figure 1.
3.2.2 Lower epidermis epidermal cells rectangular,
closely arranged, significantly higher than the wall thickness of epidermal cells. Single-cell non-glandular hair long and
narrow, long 440 ~ 1100 μm. Glandular head by a number of
cells, diameter of 12 ~ 25 μm, single-cell and a short stalk.
There are many pores, significantly more than the upper epidermis, mostly flat-axis, a small number of infinitive,
kidney-shaped guard cells, subsidiary cells 3 to 6. Epidermal cells and subsidiary cells contain a number of calcium oxalate
crystal cluster diameter of 15 ~ 38 μm, a small number of
cells contain calcium oxalate trigonal diameter of 9 ~ 25 μm.
