The raw garlic is collected from three geographical locations of India (Bihar, Maharashtra and Kashmir). A comparative study of Allium sativum having Allicin as a phytoconstituent was analyzed. LCMS/MS was used to analyse the Allium sativum samples and compared with the standard of Allicin SAC (S-allyl- cysteine) and the evaluation was presented with m/z value and retention time of standard compared with 3 samples of Allium sativum. The maximum content of Allicin was obtained in the sample of Maharashtra i.e. (1614.430ppm) when compared with standard Allicin at 2.5 minutes peak followed by sample of Bihar i.e. (1084.579ppm); sample of Kashmir i.e. (295.642ppm). With the obtained results, Allicin is comparatively found in more concentration in sample of Maharashtra and is therapeutically potent then the other samples of Allium sativum. Keywords: Allicin, Allium Sativum, LCMS-MS, m/z, Retention time. 1. Introduction Garlic is one of the most important bulb crop grown in the world. [1] The name garlic comes from an old Anglo – saxon word ‘gerleac’ which means ‘Spear leek’. [2, 3] Garlic is harvested in 1,437,690 area throughout the world and its annual production is 24,255,303 tonnes of dry bulb according to FAO, 2013. [1] It is a member of Alliaceae or Liliaceae family and botanical name is Allium Sativum. [4] It was first utilize as medicine by the sumerians. [2] Garlic has an apomictic nature which leads to the existence of extensive somatic mutation. [5] Garlic contains Enzymes, Vitamins, Flavonoids and certain Minerals. [2, 6] It is rich source of sugar, protein, fat, calcium, potassium, phosphorous, sulphur, iodine fiber and silicon. [6] The bulb contains a colorless, odorless and water soluble compound called Allicin. It is a major biologically active organosulfer compound of garlic which is formed by cutting or crushing the garlic clove, hence the potential of this plant has been assumed to be due to Allicin. [2, 6, 7, 8, 9] Allicin is effective towards most gram – Positive and gram – Negative bacteria. [10] Allicin can iduce apoptosis in cancer cells through oxidative modification of cellular sulfhydryl (thiol) groups. [8, 10] Allicin is a flavour component of Garlic. [11] Allicin were identified and quantified by using Liquid Chromatography and Mass Spectrography (LC/MS). [10, 12] Garlic contains about 0.1% volatile oil. Volume 7, Issue XI, November/2018 Page No:787 International Journal of Research ISSN NO:2236-6124 The oil is rich in sulphur, but contains no oxygen. Its constituents are diallyl disulphide (60%) diallyl- trisulphide (20%) allyl propyl disulphide (6%) with small quantity of diesel disulphide and diallyl polysulphide. [2,7] Garlic bulb comprises of 84.09% of water & 13.38% organic matter.[2] There are 20 types of sulphide compounds (eg allicin, methyl allyl trisulphide and diallyl trisulphide) reported in garlic. Seven organosulphur compounds like Alliin, soallin, methiin, cycloalliin, and gamma-1-glutanyl-s-methyl-l-cyseine, were also determined in it. [2, 7] In traditional medicinal systems of India i.e. Tibbi, Unani and Ayurveda garlic is recommended due to its healing properties. [5] In Charaka Smhita (1000 – 800 BCE) Garlic is recommended for treatment of heart diseases and arthritis. [5] Garlic has a great antioxidant activity. [13] It has anticancer, antiviral, anti-inflammatory, anti-diabetic, antimicrobial, cardio protective and immunomodulatory type of medicinal properties. [1, 2, 14] Garlic has Pharmaceutical effects and used to cure various diseases such as heart disease, arthritis, pulmonary complaints, diarrhoea, and worm infections. [5, 6, 9] It is used to prevent coronary thrombosis, atherosclerosis and stroke. [9] Garlic can reduce serum cholesterol level and inhibit cancer cell growth. [2, 9, 14] Garlic is a wonderful remedy for treating fever, cough, headache, stomach pain, haemorrhoids, asthma, bronchitis, both low and high blood sugar, hypertension and snake bites. [2] Garlic commonly used as spices and flavouring ager for foods and added taste of food. [6] The Aim of the study is to evaluate the concentration of Allicin collected from different geographical states i.e. Maharashtra, Bihar, and Kashmir by LC-MS method. 2. Materials and Methods 2.2 Samples collection: Samples of Garlic is collected from local farmers of that particular area from Bihar (gopalganj). Maharashtra (solapur), Kashmir. 2.3 Laboratory: Vimta labs Limited, Bhakti Genesis, Fifth Floor,S No. 245 H.
