What are the morphological characteristics of this plant?

Inula hookeri has a perennial herbaceous habit characterized by erect stems that typically reach heights of 30 to 60 centimeters and possess lanceolate, serrated leaves with distinctively long petioles. The foliage displays a pilose texture, meaning the surfaces are covered in fine, soft hairs that provide a slightly fuzzy appearance. Its inflorescence consists of solitary, terminal heads containing numerous yellow ray florets surrounding a central disc of tubular florets. The involucral bracts are arranged in multiple overlapping rows, protecting the developing flower head. These structural features are characteristic of the Asteraceae family and facilitate its adaptation to specific montane environments.

What is the geographical distribution of this plant?

This plant is native to the montane forests and subalpine regions of the Himalayas, specifically ranging from northern India and Nepal through Bhutan to western China. It typically thrives in high-altitude habitats where moist, temperate conditions prevail. Its distribution is closely tied to specific elevation zones within the mountainous terrain of Southeast Asia. Local populations are often found in shaded, damp areas along forest edges or near mountain streams. These ecological requirements restrict its presence to certain topographical corridors across the Himalayan belt.

This holistic approach ensures that all active compounds within the organism are captured during treatment. Such comprehensive usage is common in regional folk medicine for treating various ailments.

According to a study published by "Planta medica", the whole plants of Inula hookeri C. B. Clarke were used to isolate 4 new sesquiterpene lactones and 26 known sesquiterpene lactones. These compounds included (1 S,5 R,6 S,7 S,8 R,9 R,10 S,11 S)-6-acetoxy-9-hydroxy-4-oxo-pseudoguai-2(3)-en-12,8-olide, (1 S,2 R,5 R,6 S,7 R,8 S,10 R)-6-acetoxy-2-ethoxy-4-oxo-pseudoguai-11(13)-en-12,8-olide, (1 S,2 R,5 R,6 S,7 R,8 S,10 R)-6-acetoxy-2-hydroxy-4-oxo-pseudoguai-11(13)-en-12,8-olide, and 14-acetoxy-1 β,5 α,7 αH-4 β-hydroxy-guai-9(10),11(13)-dien-12,8 α-olide. The isolates were evaluated for cytotoxic activities against 4 specific cell lines, which were HepG2, HeLa, PC-3, and MGC-803, using a CCK-8 assay. Some of the isolates, especially the pseudoguaianoilides and guaianolides, exhibited significant cytotoxicities against these 4 examined cell lines.
