原文： Nothapodytes foetida has been reported to contain 0.06–0.1% of camptothecin and 0.001–0.02% of 9-methoxycamptothecin [16].
Camptothecin had been previously isolated from the Chinese tree Camptotheca acuminata (0.005%) [17], and in low yield from E. heyneana (0.00013%) [11].
We have evaluated the contents of camptothecin and 9-methoxycamptothecin in various parts and seed-parts of N. foetida.
In regard to various plant-parts, maximum concentrations of alkaloids were obtained in bark (0.27% of camptothecin and 0.11% of 9-methoxycamptothecin) followed by root, stem, and leaves.
In contrast, the bark of C. acuminata accumulated lower concentration of camptothecin, whereas leaves contained 2.5-fold higher than that of the bark [18]. Puri et al. [19] demonstrated that N. foetida trees cultivated in north-western agro-climatic region of Jammu, India, accumulated 0.1% dry wt camptothecin in roots and seeds, whereas bark produced lower concentrations of camptothecin.
譯文： 3. Results and discussion
依據報告青脆枝(Nothapodytes foetida)含0.06–0.1%的喜樹鹼(camptothecin)和0.001–0.02%的9-methoxycamptothecin[16]。
喜樹鹼(camptothecin)已事先自中國樹產的喜樹(Camptotheca acuminate) (0.005%)[17]析出，自E. heyneana (0.00013%)有小量的生成[11]。
我們已測定喜樹鹼(camptothecin)和9-methoxycamptothecin在青脆枝(Nothapodytes foetida)不同部位和種子中的含量。
關於不同的植株部位，在樹皮有最高的生物鹼含量(0.27%的喜樹鹼(camptothecin)和0.11%的9-methoxycamptothecin)，然後則為樹根、莖部和葉子。
相反的，喜樹的樹皮有較低的喜樹鹼濃度，而葉子的濃度則高於樹皮2.5倍[18]。 Puri等人[19]表示在印度Jammu西北地區的喜樹，在根部和種子，則有0.1%淨重的喜樹鹼，但樹皮則較低的喜樹鹼濃度。
