Their structures were established on the basis of spectral analyses as n-butyl pyroglutamate (1), nonadecyl alcohol(2), eicosanol(3), behenic acid(4), b-sitosterol(5), stigmasterol(6), glycerol 1-monocerotate(7), pyrocatechol(8), p-ethoxybenzoic acid(9), p-coumarinic acid(10), protocatechuric acid(11), ursolic acid(12), betulinic acid(13), fumaric acid(14), succinic acid(15), uracil(16), xanthine(17), quercetin(18), kaempferol (19), isorham-netin(20), adenosine(21), daucosterol(22), stigmasterol 3-O-b-D-glucopyranoside(23), quercetin 3-O-b-D-glucopyra-noside(24), kaempferol 3-O-b-D-glucopyranoside(25), rutin(26), and kaempferol 3-O-b-rutinoside(27). All of them, except compound 5, were isolated from this plant for the first time.展开更多

Ocular biometry readings between two groups were compared and analyzed statistically, lntraocular pressure was also recorded before and after lens extraction. Results Anterior chamber depth was shallower in patients with angle closure glaucoma group [ （ 1, 79 ± 0. 56 ） mm ] compared with senile cataract group [ （2.69 ±0. 40） mm ] （ P 〈 0.01 ）. Lens thickness was greater in angle closure glaucoma group [ （5.30 ±0. 61） mm ] than that in senile cataract group [ （3.84 ＋-0. 61） mm ] （ P 〈0. 01）. Phacoemusification was performed in 5 patients with persistent acute attack of angle closure glaucoma, lOPs were controlled in all five cases after lens extraction. Conclusion Eyes with angle closure glaucoma seems to have significantly shallow anterior chamber and greater lens thickness compared to senile cataract eyes in the same age. Lens extraction might be effective in those cases with such anatomy features.展开更多
