  From the heartwood of T. tomentosa Wight et Arn, β-sitosterol, oleanolic acid (VI, R = R1 = H), arjunolic acid (I) and barringtogenol (IV) were isolated and in addition a new tetrahydroxy triterpene mono-carboxylic acid, now named Tomentosic acid. The triacetylmethyl tomentosate was oxidized to the corresponding ketone (XV) which could be reduced by forced Wolff-Kishner method to give methyl arjunolate

  从毛白杨的心材中提取β-谷固醇，齐墩果酸（VI，R = R 1＝ H），分离出壬酸（I）和巴丁香酚（IV），此外还分离了新的四羟基三萜单羧酸，现称为Tomentosic acid。将三乙酰基甲基绒毛酸酯氧化为相应的酮（XV），可以通过强制Wolff-Kishner方法将其还原，得到阿魏酸甲酯（III）。上述酮在碱的存在下也经历异构化，得到α，β-不饱和酮（XVI）。此外，在内酯化过程中，酸产生三羟基脱水内酯（X）。可以使用二氧化硒使三乙酰基甲酯脱水，得到甲基脱氢阿魏酸酯（XIX）。从这些反应中，将绒毛膜酸暂定为2α，3β，19β，23-四羟基-油烯-12-烯-28-油酸（XII，R ＝ H）。

• Cyclooxygenase-2 enzyme inhibitory triterpenoids from Picrorhiza kurroa seeds

  A bioassay guided phytochemical study of the ethyl acetate extract of the seeds of Picrorhiza kurroa afforded a new triterpenoid, 2 alpha, 3 beta, 19 beta, 23-tetrahydroxyolean-12-en-28-O-beta-D-glucoside (1), along with five known triterpenoids, 2 alpha, 3 beta, 19 beta, 23-tetrahydroxyolean-12-en-28-oic acid (2), 2 alpha, 3 beta, 23-trihydroxyolean-12-en-28-O-beta-D-glucoside (3), 2 alpha, 3 beta, 23-trihydroxyolean-12-en-28-oic acid (4), 2 alpha, 3 beta, 19 beta, trihydroxyolean-12-en-28-oic acid (5), and 2 alpha, 3 beta, 6 beta, 23-tetrahydroxyolean-12-en-28-oic acid (6). Their structures were established by extensive NMR spectral studies. The acetyl derivatives, compounds 7 and 8, were prepared from compounds 1 and 2, respectively, to aid in their structure elucidation. The inhibition of cyclooxygenase-2 (COX-2) enzyme by compounds 1-6 at 100 mu g/mL was 38.3%, 39%, 37%, 49.6%, 25%, and 45.0%, respectively. However, compounds 1-6, at 100 mu g/mL, did not inhibit cyclooxygenase-1 (COX-1) enzyme. Compound 1 is a novel triterpenoid and compounds 1-6 are isolated for the first time from the seeds of P kurroa. (c) 2005 Elsevier Inc. All rights reserved.
