Environmental factors have profound effect on quantity vis-a-vis quality of phytochemicals in medicinal plants. Solanum xanthocarpum Schrad. and Wendl. is among the 10 dashmool species which is utilized in more than hundreds of Ayurvedic preparations including ‘Dashmoolarishta’. Phenolics are the pharmacologically valuable compounds. Therefore, the present study was undertaken to assess the total phenolic (TP) and Caffeic acid (CA) contents in four different plant parts i.e., leaves, fruits, stem and roots of S. xanthocarpum sampled randomly from different locations of Madhya Pradesh, a central Indian state. Plant samples were collected from 99 places of 29 districts falling in 11 agroclimatic regions of Madhya Pradesh through random sampling. UV-VIS spectrophotometer and HPTLC were used to determine TP and CA contents, respectively. Phytochemical screening was carried out using standard methods. Preliminary phytochemical screening indicates the presence of alkaloids, cardiac glycosides, flavonoids, phenols, steroids and terpenoids in all plant parts. Quantification of TP and CA contents revealed that both varied significantly between agroclimatic zones as well as within plant parts of S. xanthocarpum. Results revealed that among analysed plant parts, roots and stem harbored highest content of CA while fruits and leaves had the highest TP content. Among agroclimatic regions, accessions of Satpura plateau can be considered rich in CA and TP contents for fruits (0.030%; 28.70 mg CE/g), leaves (0.058%; 27.90 mg CE/g) and roots (0.161%; 5.17 mg CE/g). For stem, highest CA (0.100%) and TP (13.23 mg CE/g) contents were observed in samples of Malwa Plateau and Central Narmada Valley, respectively. We conclude that agroclimatic regions have significant effect on studied phytochemicals and Satpura plateau agroclimatic zone may be targeted for conservation and sustainable utilization of this valuable dashmool species if the target plant parts are fruits, leaves and roots. While, Malwa Plateau and Central Narmada Valley zones may be targeted for stem. Further, fruits and roots may be utilized for extraction of TP compounds and CA respectively.

茄属植物不同部位咖啡酸和酚类物质含量的变化。和温德尔。– 一种具有重要商业价值的 dashmool 物种

环境因素对药用植物中植物化学物质的数量和质量有着深远的影响。Solanum xanthocarpum Schrad。和温德尔。是 10 种 dashmool 物种之一，用于数百种阿育吠陀制剂，包括“Dashmoolarishta”。酚类是具有药理价值的化合物。因此，本研究旨在评估从中央邦不同地点随机取样的黄果树的四个不同植物部分的总酚 (TP) 和咖啡酸 (CA) 含量，即叶、果实、茎和根。印度中部邦。通过随机抽样从中央邦11个农业气候区29个区的99个地方采集植物样品。UV-VIS 分光光度计和 HPTLC 分别用于测定 TP 和 CA 含量。使用标准方法进行植物化学筛选。初步的植物化学筛选表明所有植物部位都存在生物碱、强心苷、黄酮类化合物、酚类、类固醇和萜类化合物。TP 和 CA 含量的量化显示，两者在农业气候带之间以及 S. xanthocarpum 的植物部分内均存在显着差异。结果表明，在分析的植物部分中，根和茎的CA含量最高，而果实和叶子的TP含量最高。在农业气候区中，桑树高原的种质可以被认为富含 CA 和 TP 的果实（0.030%；28.70 mg CE/g）、叶（0.058%；27.90 mg CE/g）和根（0.161%；5.17 mg CE） /G）。对于茎，在马尔瓦高原和中央纳尔马达山谷的样本中观察到最高的 CA (0.100%) 和 TP (13.23 mg CE/g) 含量，分别。我们得出结论，农业气候区对所研究的植物化学物质有显着影响，如果目标植物部分是果实、叶子和根，则 Satpura 高原农业气候带可能是保护和可持续利用这种有价值的 dashmool 物种的目标。而马尔瓦高原和纳尔马达中部山谷地区可能是茎的目标。此外，果实和根可分别用于提取 TP 化合物和 CA。
