Ginkgo biloba L. which is called ginkgo or gingko can date back to 300 million years ago and is considered as a living fossil. Ginkgo consists of terpenoids, like diterpenes such as ginkgolides A, B, C, J and sesquiterpene like bilobalide and triterpenes like sterols. Ginkgo biloba L. contains a vast number of flavonoids which included myricetin, kaempferol, isorhamnetin, quercetin, rutin, laricitrin, mearnsetin, apigenin, luteolin, epicatechin, catechin and genistein. Ginkgo also contains Biflavonoids which consists of sciadopitysin, ginkgetin, isoginkgetin, amentoflavone and bilobetin. Allium with around 800 species is an important genus of Amaryllidaceae family which widely spread in the northern hemisphere. Leeks (Alllium ampeloprasum var. porrum) are robust, winter-hardy biennials that do not form a hard bulb like onions or garlic. Instead, they are grown for their long and thick white stem. Persian leek is one of the most widely used herbal foods among Iranians. Peganum harmala L. (Zygophyllaceae) has been a famous plant in traditional and folk medicine, and it is used in both endemic regions and other parts of the world. Peganum harmala. Belongs to Asian origin and grows in the Middle east and in part of South India and Pakistan and west of China, is a medicinal plant of the family Nitrariaceae. Peganum harmala is a perennial herbaceous, glabrous plant which can grow 30-100 cm and mainly disturbed throughout the Middle East, North Africa, and Central Asia. The plant is not usually grazed by animals due to its bitter taste. Its seeds showed that alkaloids belonging to the -carboline family such as harmine, harmaline, Harman, harnol and harmalol are responsible or a wide range of pharmacological effects. The main compounds from Peganum harmala seeds are dodecane, tetradecane, methyl dodecanoate, hexadecane, 2-Octanol benzoate, heptadecane, methyl tetradecanoate, 2,6,10,14-tetramethyl pentadecane, octadecane, 2,6,10,14-tetramethyl hexadecane, nonadecane, methyl hexadecanoate, dibutyl phthalate, eicosane, methyl oleate, henicosane, docosane, harmine and tricosane. The most important properties of Peganum harmala are anti-cholinesterase, anti-tumor angiogenesis, antiparasitic effect, anti-inflammatory effect, cytotoxicity effect, antioxidant effect, cerebroprotective effect, hempatoma cancer effect, hepatoprotective prevention effect, hypoglycemic effect, antibacterial effect, pesticide effect, antitumor effect, antinociceptive effects, haemosporidian infections effect and different unknown beneficial properties. This review article suggests the important potential of P. harmala to be employed in both new western and eastern therapeutic drugs. This review article emphasizes on the need of widespread researches and studies for covering the supplementary information and knowledge on the importance of medicinal crops. Smilax china consists of fat, Saponins, glucosides, gum, starch, flavonoids, tannins and alkaloids.
