Inula racemosa Hook. f. and Digitalis purpurea L. are aromatic medicinal plants used in Ayurveda, possessing diuretic, antiseptic, antitumor, and various other therapeutic properties. This study determined fatty acid composition by gas chromatography‐mass spectrometry in petroleum ether seed extracts. Moreover, antioxidant activity namely 2,2‐di‐phenyl‐1‐picrylhydrazyl (DPPH), 2,2ˈ‐azino‐bis‐3‐ethylbenzothiazoline‐6‐sulphonic acid (ABTS), nitroblue tetrazolium (NBT), catalase, peroxidase, and in vitro antibacterial activity, functional group analysis were carried on seeds extracted through petroleum ether, ethyl acetate, acetone, and methanol. Extracted yield (wt. %) of seeds was significantly high. Linoleic acid was the dominant fatty acid found in I racemosa 52.87% and D purpurea 73.36%. All extracts showed powerful antioxidant and antibacterial activities especially at 100 and 100 mg/mL, respectively. Moreover, through Fourier transform infrared spectroscopy numerous functional groups were found in all extracts. Therefore, from above study the I racemosa and D purpurea seeds could have valuable application in food, cosmetic, and pharmaceutical industries.

克什米尔的菊苣和洋地黄：脂肪酸组成，抗氧化剂，抗菌活性和官能团评估

旋覆花竞速钩。F。洋地黄和洋地黄是用于阿育吠陀的芳香药用植物，具有利尿，防腐，抗肿瘤和其他多种治疗特性。这项研究通过气相色谱-质谱法测定了石油醚种子提取物中的脂肪酸组成。此外，抗氧化剂活性为2,2-二苯并-1-吡啶并肼基（DPPH），2,2-二氮杂双-3-乙基苯并噻唑啉-6磺酸（ABTS），硝基蓝四唑（NBT），过氧化氢酶，过氧化物酶并通过石油醚，乙酸乙酯，丙酮和甲醇对种子进行了体外抗菌活性，官能团分析。种子的提取产率（重量％）非常高。亚油酸是发现于我racemosa 52.87％和紫癜73.36％。所有提取物均显示出强大的抗氧化和抗菌活性，尤其是分别在100和100 mg / mL时。此外，通过傅立叶变换红外光谱法，在所有提取物中都发现了许多官能团。因此，通过以上研究，总状花蕾和紫丁香种子可能在食品，化妆品和制药行业中具有有价值的应用。
