Objective: To study the chemical constituents in the fruits of Acanthopanax gracilistylus.
Methods: The chemical components were isolated and purified by silica gel, ODS C-18, and Sephadex LH-20 column chromatogram. The chemical structures were elucidated on the basis of physicochemical properties and spectral data.
Results: Ten compounds were isolated and identified as acankoreoside D(1), 3alpha, 11alpha-dihydroxylup-20(29)-en-28-oic acid(2), 3/3-([O-beta-D-glucopyranuronosyl] oxy) -olean-12-ene-28-olc acid (3),3beta-([O-beta-D-glucopyranuronosyl]oxy)-28-O-P3-D-glucopyranosyl-olean-12-ene-28-olc acid(4),oleanolic acid-3-O-6'-O-methyl-beta-D-glucuronopyranoside(5), acantrifoside A(6), acankoreoside A(7), (-)-kaur-16-en-19-oic acid(8), protocatechuic acid (9),beta-sitosterol(10).
Conclusion: Compounds 2-5 are obtained from the fruits of the plant for the first time.

Medicinal plants often harbour various endophytic actinomycetia, which are well known for their potent antimicrobial properties and plant growth-promoting traits. In this study, we isolated an endophytic actinomycetia, A13, from the leaves of tea clone P312 from the MEG Tea Estate, Meghalaya, India. The isolate A13 was identified as Streptomyces sp.

Photosensitization has a wide range of applications in vastly distant fields. Three key components must be present at the same time to trigger the related photodynamic effect: light, the photosensitizer (PS) and oxygen. Irradiating the sensitizer leads to the formation of reactive oxygen species (ROS).
