In this report, two new steroidal glycosides were isolated and determined from n-butanol
fraction of A.asphodeloides. The structures were confirmed in comparison with the spectral data of
known compounds by using different spectroscopic analysis approaches including 1D & 2D-NMR
techniques and HRMS. The anti-proliferation screening against cancer cell lines A549 and HeLa indicated
that compound 1 exhibited good inhibitory activities with IC50 values of 0.79 and 0.55 µg/mL,
respectively.
Vuong Huu Quang 王有光, with courtesy name Dung Hoi用晦 and poetic name Te Trai 濟齋, was a high-ranked mandarin of the Nguyen Dynasty. He was born in Tan Duc Village, Tan Long District, Phien An Town, Gia Dinh Province, Southern Vietnam, into a family of the Ming-Dynasty immigrants who originated from CangZhou County, Fujian Province. Vuong Huu Quang held many important positions in the imperial court across various localities and traveled to China for diplomatic mission twice in the fifth year of Thieu Tri Emperor (1845) and from the seventh year of Thieu Tri (1847) to the first year of Tu Duc Emperor (1848). His name, however, is unfamiliar to Vietnamese modern readers due to his limited written legacy, most of which was lost in history. Researchers have known of only two steles poems he left in China, one engraved on a stele in Wuxi and the other in the Yue Fei Temple. Upon reading the old collection Viet Nam Han van Yen hanh van hien tap thanh 越南漢文燕行文獻集成, I discovered that Vuong Huu Quang and his co-worker Pham Chi Huong enjoyed writing and responding in poetic form during their diplomatic trips to China. This article introduces several more poems of Vuong Huu Quang to expand our understanding of another Southern Vietnamese poet who have been mostly covered by time, and provides a brief analysis on the poetic style that Vuong Huu Quang and Pham Chi Huong applied in portraying historical figures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
