A clear, clear, colorless to yellow or yellow-green liquid with a sweet, cool, light herb aroma. Soluble in more than 80% ethanol.
with Labiatae perennial plant mint (commonly known as spearmint) fresh stems, leaves as raw material, using steam distillation method, if necessary, can be further distilled.
The biggest use of spearmint oil is for toothpaste, mouthwash, etc., a large number of used in oral hygiene products. China's GB 2760-1996 is allowed to use the edible spices, the largest amount of food is used for gum, as a fragrance; Hard Candy is also used. It can also be used as a modifier of peppermint oil and as a repellent.

Application | , doing wind-driving and aromatic stimulant [3]. Leaves, shoots or whole grass were used for the treatment of cold, fever, Cough, flatulence, bruising pain, red eyes and hot pain, aconite, chicken coop cold, whole body numbness and infantile sore. Pharmacological studies have shown that: Spearmint has anti-fungal activity and anti-inflammatory activity [4]. For the treatment of bone degeneration, arthritis, bursitis, sinusitis and other inflammation, has also been reported with antiviral activity [5]. At home and abroad, the chemical constituents and pharmacological studies of the genus Mentha are more in-depth, in which there are many reports on the research of Mentha [6,7], and the research on Mentha is less, about Non-domestic Spearmint volatile oil composition has been reported abroad [7] domestic research mainly on mint more.|
extraction method | 1. Improved steam distillation method weigh 10g spearmint stem powder into triangle flask, take 100ml distilled water into the bottle, directly soak Spearmint stem powder for 10-12H. Then the alcohol lamp is heated, and the steam condensed and distilled by a straight condenser tube is mainly a mixture of water and spearmint essential oil, which is distilled for 5h, and then a colorless liquid is collected, which contains spearmint essential oil. 2. Organic Solvent extraction method 2.1 Crude extraction of essential oil ethanol, ether, acetone and cyclohexane were used as extraction solvents respectively: weigh 10g of spearmint stem powder in a self-made filter paper pouch, tie it with a string and put it into a Soxhlet Extractor. To be extracted, take 100mL of organic solvent and several particles of zeolite (to prevent boiling), the water bath was heated to the boiling point of the organic solvent used. The solvent vapor rises to the condenser tube, and drops to the pouch containing Spearmint powder by cooling and reflux. The Spearmint pouch immersed in organic solvent drops the extract back to the round bottom bottle, and then water bath, the cool-back Leach (green leaching solution due to the presence of the pigment) was raised and circulated until the dip into the round bottom flask was as colored as the new leach solution. The organic solvent with the highest yield of essential oil in the above experiment was selected, and then the mixture of the two with different proportions was extracted, so that the extraction rate could be broken through by a suitable ratio of the two. The test procedure was as above. decolorization of 2.2 crude extract after crude extraction, some pigment substances were also extracted, Therefore, the crude extract should be decolorized. The decolorization method is: Pour the crude extract of spearmint essential oil into a beaker, add 3-4 spoonful of activated carbon, then heat to boiling with an electronic temperature-regulating electric heating sleeve, and stir for 15min At the same time, after cooling, a bleed was performed, and the decolorized spearmint essential oil was collected. 2.3 evaporation of spearmint filtrate The Spearmint filtrate was replaced by a round-bottom flask with a grinding mouth, the solvent is evaporated with a rotary evaporator connected with a pressure-reducing pump, the vapor enters the serpentine reflux condenser, is cooled to a liquid, and is collected with a beaker, the remaining spearmint essential oil can be collected until the solvent-free drip drops. |
content analysis | determination by neutral sulfite method according to Method 3 in the aldehyde and ketone assay (OT-7). The ketone content in terms of carvone was thus determined. |
toxicity | GRAS(FDA,§ 182.20,2000). LD50 5000mg/kg (rat, oral). |
usage limit | FEMA (mg/kg dissolved in 80% ethanol of the same volume): Beverage 100; wine 100; Cold drinks 81; Candy 830; Jelly 75; Gum 6200; Baked goods 270; Mint frozen 72~1900. |
Use | is mainly used for the preparation of toothpaste and chewing gum flavor. as a food spice, it is the main raw material of spearmint flavor. It can also be used directly in foods such as candy, chewing gum and cakes. The usage amount is 830mg/kg in candy; 270mg/kg in baked food leaves; 100mg/kg in beverage; 100mg/kg in alcohol; 81mg/kg in cold drink leaves; 75mg/kg in jelly. GB 2760-96 provides for the permitted use of flavorants. Mainly used for gum, hard candy, cakes and the preparation of spearmint flavor. |
production method | The Labiatae plant Mentha.Spicata; Also known as ordinary spearmint) or small leaf mint (Mentha cardiaca; Also known as Scottish spearmint) fresh stems, leaves and other plants by steam distillation. If necessary, it can be further refined by distillation. The yield was 0.3%-0.7%. Mainly produced in the United States, Germany and Britain, China's Jiangsu, Zhejiang also have a large number of production. The whole plant of spearmint, a Labiatae perennial herb distributed in Zhejiang, Henan, Sichuan, Jiangsu, Guangxi, Jiangxi, Guangdong and Anhui, was obtained by water distillation, the oil yield was 0.3%-0.6% (see Asian peppermint oil 22045). |
