Neem tree (Azadirachta Indica), grows well in tropical Indian conditions. Traditionally, Neem products are used by Indian people, for treating diseases like Chikenpox etc. It has very good antibacterial, antiviral, antifungal, gingivitic or larvicidal activity – in used in controlling pests and diseases.
In the Neem range of products, We Offer following
- Azadirachtin technical powder – 15% to 30% concentrations
- Neem Oil – cold pressed
- Neem cake
Azadirachtin:
Occurance: It is found in the seeds (0.2 to 0.8 percent by weight) of the neem tree, Azadirachta indica. Many more compounds, related to azadirachtin, are present in the seeds as well as in the leaves and the bark of the neem tree which also show strong biological activities among various pest and insects. Because pure neem oil contains other insecticidal and fungicidal compounds in addition to azadirachtin, it is generally mixed at a rate of 1 ounce per gallon (7.8 ml/l) of water when used as a pesticide.
Chemistry: It is a chemical compound belonging to the limonoid group, and a secondary metabolite present in neem seeds. It is a highly oxidized tetranortriterpenoid which boasts a plethora of oxygen bearing functional groups, including an enol ether, acetal, hemiacetal, tetra-substituted epoxide and a variety of carboxylic esters.
Azadirachtin has a complex molecular structure; it presents both secondary and tertiary hydroxyl groups and a tetrahydrofuran ether in its molecular structure, alongside 16 stereogenic centres, 7 of which are tetrasubstituted.
Preparation: Azadirachtin is prepared by solvent extraction of Neem seeds, followed by evaporating it. Normally, the prepared powder contains 15% to 30% of active Aza A + B species, based on the Neem kernel quality.

Neem Oil – Cold Pressed
Neem oil is the most useful concentrated by product from Neem tree. Neem oil is extracted from Neem kernel. Neem oil cold-pressed contains Azadirachtin concentration around 2000 PPM to 2800 PPM. Neem oil cold-pressed when extracted under certain regulated parameters is stable and does not lose its properties during storage. Nimbin is another triterpenoid which has been credited with some of neem oil’s properties as an antiseptic, antifungal, antipyretic and antihistamine. Neem oil also contains several sterols, including (campesterol, beta-sitosterol, stigmasterol).
Neem oil varies in color; it can be golden yellow, yellowish brown, reddish brown, dark brown, greenish brown, or bright red. It is composed mainly of triglycerides and contains many triterpenoid compounds, which are responsible for the bitter taste. It is hydrophobic in nature; in order to emulsify it in water for application purposes, it must be formulated with appropriate surfactants.
Uses
Neem oil is not used for cooking purposes. It is used for preparing cosmetics (soap, hair products, body hygiene creams, hand creams) and in Ayurvedic, Unani, traditional medicine, in the treatment of a wide range of diseases. Traditional Ayurvedic uses of neem include the treatment of acne, fever, leprosy, malaria, ophthalmia and tuberculosis. Other remedies for neem include use as an anthelmintic, antifeedant, antiseptic, diuretic, emmenagogue, contraceptive, febrifuge, parasiticide, pediculocide and insecticide. It has been used in traditional medicine for the treatment of tetanus, urticaria, eczema, scrofula and erysipelas. Traditional routes of administration of neem extracts included oral, vaginal and topical use. Neem oil has anlist-style-type: lower-alpha; extensive history of human use in India and surrounding regions for a variety of therapeutic purposes.
Formulations made of neem oil also find wide usage as a biopesticide for organic farming, as it repels a wide variety of pests including the mealy bug, beet armyworm, aphids, the cabbage worm, thrips, whiteflies, mites, fungus gnats, beetles, moth larvae, mushroom flies, leafminers, caterpillars, locust, nematodes and the Japanese beetle.
Neem oil is not known to be harmful to mammals, birds, earthworms or some beneficial insects such as butterflies, honeybees and ladybirds if it is not concentrated directly into their area of habitat or on their food source. It can be used as a household pesticide for ant, bedbug, cockroach, housefly, sand fly, snail, termite and mosquitoes both as repellent and larvicide. Neem oil also controls black spot, powdery mildew, anthracnose and rust fungi.
Packing: We provide different packings from 50 kg to bulk packings, based on customer needs. We also provide low Azadirachtin ( 150 to 300 ppm), containing neem oil ( mixed oil) for Urea coating purpose.
Neem cake
Neem cake is the residual, after extraction of Neem oil from neem kernel. It is a potential source of organic manure , Neem has demonstrated considerable potential as a fertilizer.
Composition of Neem Cake
Neem cake has an adequate quantity of NPK in organic form for plant growth. Being a totally botanical product it contains 100% natural NPK content and other essential micro nutrients as N – 2.0% to 5.0%, P- 0.5% to 1.0%, K – 1.0% to 2.0%, Ca – 0.5% to 3.0%, Mg – 0.3% to 1.0%, S – 0.2% to 3.0%), Zn, Cu, Fe, Mn in trace quantities. According to research, neem cake seems to make soil more fertile due to an ingredient that blocks soil bacteria from converting nitrogenous compounds into nitrogen gas. It is a nitrification inhibitor and prolongs the availability of nitrogen to both short duration and long duration crops.
Use as a fertilizer
Neem cake organic manure protects plant roots from nematodes, soil grubs and white ants probably due to its residual limonoid content. It also acts as a natural fertilizer with pesticidal properties. Neem cake is widely used in India to fertilize paddy, cotton and sugarcane.
Neem seed cake also reduce alkalinity in soil, as it produces organic acids on decomposition. Being totally natural, it is compatible with soil microbes, improves and rhizosphere microflora and hence ensures fertility of the soil. Neem cake improves the organic matter content of the soil, helping improve soil texture, water holding capacity, and soil aeration for better root development.
