Abstract

Phytochemical screening of the extracts has shown the presence of steroids, flavonoids, saponins, glycosides, tannins, phenolic compounds, fixed oils, and fats in Jurinea dolomiaea root extracts. The presence of lupeol has been reported previously by us using high-performance thin-layer chromatography and high-performance liquid chromatography. Present research studies encompasses identification of chemical constituents in Jurinea dolomiaea roots of methanol extracts by hyphenated technique such as gas chromatography-mass spectroscopy (MS) which when coupled gives a clear insight of constituents. The components were identified by matching mass spectra with MS libraries. There were 5 different compounds analyzed from Jurinea dolomiaea roots. The identified components are (2,4-ditert-butylphenyl)-5-hydroxypentanoate, 2‑ethylhexylheptadecyl sulphite, 6-methyltridecane, (9E, 12E)-9,12-Octadecadienoyl chloride, Linoleic acid chloride, linoleoyl chloride, Lup-20 (29)-en-3-ol Lup‑20(29)‑en‑3β‑ol Lup‑20(29)‑en‑3α‑ol Lupeol, (3α)‑isomer Lupeol, (3β,18β,19β)‑isomer, in Jurinea dolomiaea root extracts.

天竺葵根提取物化学成分的色谱和光谱结构鉴定
植物化学筛选表明,白云木根提取物中存在类固醇、类黄酮、皂苷、糖苷、单宁、酚类化合物、固定油和脂肪。我们以前用高效薄层色谱法和高效液相色谱法报道过芦皮醇的存在。目前的研究包括通过气相色谱-质谱(MS)等联用技术鉴定白云木甲醇提取物根中的化学成分,当联用时可以清楚地了解成分。通过质谱与质谱库的匹配,鉴定组分。从白云木根中分析了5种不同的化合物。经鉴定的成分为(2,4-二叔丁基苯基)-5-羟基戊酸酯、2-乙基己基七烷基亚硫酸盐、6-甲基三烷、(9E, 12E)-9,12-十八烷基二烯二烯酰氯、亚油酸氯化物、亚油酰氯、Lup-20 (29)-en-3-醇Lup-20 (29)-en-3- β -醇Lup-20 (29)-en-3- α -醇Lupeol、(3α)异构体Lupeol、(3α)异构体Lupeol、(3β,18β,19β)异构体。

期刊介绍: Indian Journal of Natural Products and Resources (IJNPR), a quarterly journal, is dedicated to the exploration of topics that confront both educators, frontline workers in the fields, entrepreneurs and ultimate users of the value added products and their resources pertaining to both plants and animals. It publishes original research papers, reviews and short communications. The scope of the journal is multidisciplinary especially of applied nature. Papers on plant cultivation, fishery, apiary, poultry, dairy, disease and pest control measures, postharvest technology/practices, value added products and utilization of plants and animals in broader sense (including ethnobotany and pharmacology) are considered for publication.
