TL;DR: The extract of Rhododendron setosum and the essential oil of Eucalyptus globulus were most effective against Escherichia coli and Staphylococcus aureus respectively but the extracts of Azadiracta indica and Elsholtzia fructicosa were found to be mosteffective against Klebsiella species.
Abstract: Use of plant based drugs and chemicals for curing various ailments and personal adornment is as old as human civilization. Plants and plant-based medicaments are the basis of many of the modern pharmaceuticals we use today for our various ailments. The aim of the study was to find out the bioactive chemical constituents and to evaluate the antimicrobial activity of the ethanolic extract of traditionally used eight medicinal plants of Nepal. A qualitative phytochemical analysis was performed for the detection of alkaloids, glycosides, terpenoids, steroids, flavonoids, tannins and reducing sugar. The highest yield of ethanolic extract was found in Azadiracta indica (29.08%). Ocimum santrum contained all the chemicals except flavonoids and reducing sugar however the Colquhounia coccinea lacked alkaloids and reducing sugar. The antimicrobial activities of these plants extract were also observed. The extract of Rhododendron setosum and the essential oil of Eucalyptus globulus were most effective against Escherichia coli and Staphylococcus aureus respectively. But the extracts of Azadiracta indica and Elsholtzia fructicosa were found to be most effective against Klebsiella species.

TL;DR: Coriander is among such most commonly used spices, possessing the nutritional as well as medicinal properties, widely distributed and mainly cultivated for the seeds which contain an essential oil and the monoterpenoid-linalool.
Abstract: Medicinal plants have therapeutic potential due to the presence of natural antioxidants functioning as reducing agents, free radical scavengers and quenchers of singlet oxygen. Majority of their antioxidant activity is due to bioactive compounds viz. flavones, isoflavones, flavonoids, anthocyanins, coumarins, lignans, catechins and isocatechins. Currently there has been an increasing interest to identify the antioxidants that are pharmacologically potent with low or no side effects for use in preventive medicine. Spices have been recognized to possess several medicinal properties (diuretic, expectorant, laxative, anti-bacterial, anti-pyretic etc.) and have been effectively used in the indigenous systems of medicine in India and other countries. Apart from the traditional use, a no. of beneficial physiological effects have been identified by extensive animal studies. Among these are their beneficial effects on lipid metabolism, efficiency as antidiabetics, ability to stimulate digestion and to inhibit platelet aggregation, antioxidant, antilithogenic and anti-inflammatory potential. Many spices and their active principles are reported as excellent nutraceuticals. Coriander is among such most commonly used spices, possessing the nutritional as well as medicinal properties, widely distributed and mainly cultivated for the seeds which contain an essential oil and the monoterpenoid-linalool. Coriander is used in the preparation of many household medicines to cure bed cold, seasonal fever, nausea, vomiting, stomach disorders and also used as a drug for indigestion, against worms, rheumatism and pain in the joints. Many of healing properties of coriander can be attributed to its exceptional phytonutrients and hence, it is often referred to as store house for bioactive compounds.
