Roots or storon of Glycyrrhizia glabra L. commonlly called licorice, which is used for over 2000 years, mainly as a sweetening agent and a drug. Licorice known to contain the pentacyclic triterpene saponin glycyrrhizinic acid, which belong to the b-amyrin series. Licorice is presently recognized for its sweet tast and pronounced to be effective as an anti – inflammatory, anti-allergenic and anti-ulcer agent. Most of licorice determination methods of glycyrrhizin in the roots are non-specific and relying on indirect methods. The results obtained from these methods are usually unreal and unreliable. In this research glycyrrhizin in plants was estimated directly by High Performance Liquid Chromatography without hydrolysing glycyrrhizin to its aglycone. All sample collected from Iranian National Botanical Garden, then after extraction, component identified with compare standard. Hence the existing problems that considerably change results are eliminated. In this method, glycyrrhizin was separated from other components of total extract using reverse phase HPLC and the results of determinations have been satisfactory and reproducible.

Consumption of in organic compounds from plants source are very noticeable from different aspects to science. However these compounds are useful to prevent and treating the diseases, but they can be harmful if used more than usual. Not only the measurement of these elements enable us to use them appropriatly in food, hygenic, pharmaceutical and cometic products but also it lets us to Know relationship between plants and their field collected.
In this research gum of Astragalus gossypinus are collected from Chaharmahal Bakhtiuary, Kermanshah, Hamedan and Fars provinces, of Iran and gum used in order to determination of mineral compounds including N, P, K, Na, Mg and Ca.
Determination was done by colorimetric, Flamephotometery, Kjeldahl and Complexometery method.
In this study the phosphorus has at least and Calcium has the highest percentages of others inorganic elements.

The genus of Matricaria chamomilla L. is one of the most important of medicinal plants used in medicinal and cosmetics industries. In pharmacogonosy, consideration of the chemical composition and pharmacological properties of chamomile can be undertaken, to be clearly understod. Plant material were collected from three different locality, 1st sample from 22 Km away from Kazeroon city, and seconed sample from Research Institute of Forests and Rangelands Tehran on end of May 2000 , and third sample from Hamedan city on end of July 2000, and all three samples essential oils obtained from flowerheads by hydrodistillation method clevengar type. The essential oils were analyzed by capillary GC and GC/MS. Main components of sample were from Kazeroon: a- bisabolol (51%), trans–trans–farnesol (17 %), cis-b-farnesene (11.5%), guaiazulene (4 %), and chamazulene (2.6%), from Hamedan: trans–trans– farnesol (39.7%), a-bisabolol oxide B(18.5%), guaiazulene(17%), and cis-b- farnesene (6.9%), and from Tehran: trans–trans–farnesol(66%), guaiazulene(16.2%), a-bisabolol oxide A (11%), and cis-b-farnesene(4.4%). A major compuend from Kazeroon sample was a-bisabolol, its reported to have anti-inflammatory, can used in our medicinal and cosmetics industries.

There are meny inorganic elements in medicinal plants. These elements are useful for human body and growing of plants. Therefor measurement and determination of elements such Ca, Mg, Na, N, P, K is very importante in plants. In thes investigation, Echium amoenum petal is collected from Alborz Research farm station in karadj. In this study for determination of elements we used flam photometer, kjeltce, spectrophotometer apparatuses and titration method. Elements content of the plant were as follows Ca (4 ppm), Mg (1.8 ppm), Na (115.5 ppm), N (% 0.358), P (32.28 ppm) and K (46.54 ppm).

Ozone layer depletion has increased ultraviolet-B radiation influence. As this radiation has harmful effects on plants, this research studies the essential oils quality and quantity changes of Fennel all affected by high ultraviolet radiation emanated form a 40-watt lamp in the field conditions in three phases: before flowering, flowering and after the formation of seed. Fennel is one of the precious medicinal plants widely used in pharmacy, purfurm, cometic and hygienic industries as well as food industries. The seeds or fruits of this plant have so much essential oils that medicinal properties of the plant are attributed tothis essential oils. The water and steam distilled (Long & Kaiser) essential oils of seeds, flowers, leaves and stems of Fennel in different vegetative phases was analyzed by GC and GC/MS. The amount of essential oils in leaf, stem, flower and seeds has been decreased in the most of phases and essential oils’ components changed under ultraviolet radiations. The amount of Trans-anthole, which is the most important compound of this essential oil, has been decreased in the seed and flower of under treatment plants but this compound has been increased in the stem in spite of less amount of essential oils in this organg, this compound has been decreased in leaf before flowering phase but incraesed in flowering period. The other main compounds, Estragol, Fenchon and Limonene have been increased, in most cases. This results indicates this plants is very sensetive to ultraviolet radiations.

The genus of Thymus Presents 14 species, which are found wild in different regions of Iran (1). One of the more distributed of these species is Thymus pubescens (2).
The aerial parts of Thymus pubescens were collected from three various localities of Lar valley (in East of Tehran province). Essential oils isolated by steam distillation from the plant material at two stages, before flowering (BF) and full flowering (FF). Yields of essential oils were 0.53% to 0.93% (at BF stage) and 1.23% to 2.03% (at FF stage). Therefore the oil content at BF stage was less than FF stage.
At BF stage 26 compounds (representing 98% to 99.3% of the oils) and at FF stae 32 compounds (representing 97.7% to 98.5% of the oils) were characterized. Major constituents at BF stage were: carvacrol (52.6% - 77.9%), thymol (2.7%-21.8%), g-terpinene (3.3%-7.4%), p-cymene (2.2%-4.4%), and b-caryophyllene (1.7%-2.5%). Major constituents at FF stage were: carvacrol (54.7% - 69.2%), p-cymene (6.7%-9.7%), borneol (1.7%-5.1%), methyl carvacrol (0.6%-6.6%) and 1,8-cineol +limonene (1.7%-3.2%).
Twenty-three constituents were common at two stages. d-cadinene, thymyl acetate and g-muurolene (E)-b-ocimene were found just at BF stage and a-phellandrene, a-terpineole, terpinen-4-ol, spathunelol, camphor, linalool, methyl linalo, methyl thymol, thymoquinone and thymodihydroquinone were found just at FF stage.
