Two new sesquiterpene lactone glycosides were isolated from the whole plant of Sonchus transcaspicus. Their structures were elucidated as 1β-O-β-D-glucopyranosy-5α, 6β H-eudesma-3-en-12, 6α-olide and 1β-O-β...Two new sesquiterpene lactone glycosides were isolated from the whole plant of Sonchus transcaspicus. Their structures were elucidated as 1β-O-β-D-glucopyranosy-5α, 6β H-eudesma-3-en-12, 6α-olide and 1β-O-β-D-glucopyranosy-15-O-(p-hydroxylphenylacetate)-5α, 6β H-eudesma-3, 11(13)-dien-12, 6α-olide by spectral methods (HRMS, 1D and 2D NMR).展开更多

It is an important aspect of their sexual attractiveness, a sense of well being and a sense of self confidence. Vitiligo is an acquired depigmentation disorder of skin affecting 1% - 4% of the world population. Neither life threatening nor symptomatic (except that depigmented patches burn easily when exposed to the sun) the effects of vitiligo can be cosmetically and psychologically devastating. Because the disease is still not understood, there is a plethora of different treatments approaches, but they are largely unsatisfactory from patient’s perspective. Objective: To report the outcomes from oral use of an infusion of leaves of Solanum paniculatum L., Jacaranda brasiliensis and Sonchus oleraceus for treatment of vitiligo. Ethical issues: Study approved by the Research Ethics Committee of Hospital Federal dos Servidores do Estado do Rio de Janeiro (CAAE: 32143314.9.0000.5252). All participants confirmed the condition of volunteer by signing the Informed Consent Form. Methods: From October 2014 to October 2015 twelve subjects consumed daily four glasses (800 ml) of proposed phytotherapeutic preparation. Results: All subjects were highly satisfied about their outcomes. Total depigmentation was considered as a positive outcome because it is cosmetically acceptable. Total depigmentation was observed in presence of 80% or more of depigmenteted patches. Conclusions: The phytotherapeutic preparation proposed is effective on treatment of depigmenteted patches in vitiligo.展开更多

Antitumor activities of methanol extracts of the six plants were measured in vitro using three human tumor cell lines （breast, lung and CNS cancers） while antifolate activities were assessed using commercial dihyrofolate reductase obtained from Sigma Co. Among the six plant extracts tested, the most remarkable were those of Caralluma sinaica and Fagonia tenuifolia. Caralluma extract showed strong antitumor activity （low GIso） against the three human tumor cell lines. Fagonia extract, on the other hand, was quite inhibitory to the growth of CNS cancer and breast cancer cell lines but much less so against lung cancer cells. Extracts of both Sonchus oleraceus and Caralluma sinaica were strongly inhibitory to DHFR. These results suggest that the mechanism of anticancer activity of Caralluma plant is through DHFR inhibition but that of Fagonia may follow a different path.展开更多
