Moringa peregrine (Forssk.) Fiori is one of the species growing in tropical and desert areas and is distributed in the southeastern of the country in Hormozghan and Sistan and Balochestan provinces. Moringa peregrine is a desert shrub that can grow in areas with little rainfall, andit has a great nutritional, pharmaceutical, environmental, industrial and economic values. This research was aimed to determination of fatty acids in Moringa peregrina seed oil from different locations in Sistan and Balochestan province in 2009. Five samples were collected from five natural research stations. The oil content was determined by the Soxhlet method. The oil content obtained from Tong Fonoj, Keneshky, Bent, Begaband, and Dorahy Chanf sations were measured to be 54.6%, 50.4%, 52.4%, 53.2%, and 53.6% respectively. According to the obtained results, fatty acids content varied as follows: oleic acid (71.5-74%), palmitic acid (12.6-14.7%), Iso-oleic acid (3.6-4.5%), palmitoleic acid (3.3-4.7%), stearic acid (1.9-2.4%), Behenic acid (0.9-1.5%), gadoleic acid (0.4-10.9%) and Arachidonic acid (0.4-1.3%). Over 90 percent of the oil consumed in the country is imported from abroad. Our results clearly indicate that due to the amount of fatty acids in Moringa peregrina seeds, this plant can be considered as a new source for the production of vegetable oil and widespread food consumption.

Hypericum genus is one of the most important medicinal plants in Iran. Currently in Iran, there are 17 herbaceous, perennial and shrub species of Hypericum of which three species are endemic to Iran. This research was aimed to investigate Hypericine content in nine species of Hypericum. For Hypericine content 1 gram of plant was extracted in two steps, chloroform extraction then methanol extraction using a Soxhlet device. Hypericin content was measured by HPLC, using the following condition, mobile phase: (methanol 68%, ethyl acetate 20% and sodium hydrosulphate (0.1 M) 12%) and stationary phase C18, and UV detector: set on 590 nm. Generally, no hypericin was detected in different organs of H. androsaemum L. Hypericine content detected in flowers, leaves and stems were: H. apricum Kar. & Kir. (in flowers 0.061% and leaves 0.005%), H.armenum Jaub. & Spach (flower 0.003%), H.asperulum Jaub. & Spach (in flower 0.025%, leaves 0.004% and stems 0.003%), in H.hirsutum L. (flower 0.007%), in H.linarioides Boss. (flower 0.007%), in H.tetrapterum Fries (flowers 0.008%, leaves 0.014%, and stem 0.001%), and H.vermiculare Boiss. & Hausskn. (flowers 0.005%), in H.perforatum L. (flowers 0.124%, leaf 0.028% , stem 0.003).

Eucalyptuses trees as the fast-growing forest species are native to the Pacific. This species were introduced to Iran more than 100 years ago and cultivated in the south, having perfect environment for them. This research was aimed to investigate seasonal fluctuations of essential oil and1,8-cineol content in Eucalyptus species of Fars province. The leaves of 14 Eucalyptus species were collected from Fars province in the middle of each season for two years (2007 & 2008). Afterward, essential oils were obtained by hydrodistillation method and compounds were identified by GC and GC/MS. Results showed that in each region, some of the species had the highest essential oil yield and quality; therefore due to the high essential oil content and 1,8-cineol, they could be recommended for large-scale cultivation in the region in order to extract essential oil. Studied Eucalyptus included: E. calcicultrix (Miq.) Blakely; E. camaldulensis var. camaldulensis Dehnh.; E. cornuta; E. fruticetorum; E. intertexta R.T. Baker; E. largiflorens F. Muell.; E. lesouefii; E. longicornis F. Muell.; E. oleosa F. Muell.; E. rudis Endl.; E. salmonophloia F. Muell.; E. salubaris; E. stricklandii Maiden; E. viridis. The essential oil yield of different species at different seasons differed from 1.0 to 6.8% in 2007 and 0.3 to 5.8% in 2008. According to the results, the highest oil yield in autumn (5.2%-6.4%), the highest percentage of 1,8-cineole in winter (91.4%-94%), and the best time to harvest were recorded for E. oleosa F. Muell at Shousni, Mamasani; therefore, E. oleosa F. Muell could be recommended for cultivation as the best species.
