Stigmasterol, stigmasta-5,22-dien-3-O-?-D-glucoside, ?-sitosterol, and sitosterol-3-O-?-D-glucoside were obtained from the organic solvent extractives of different parts of Phyllanthus species P. niruri, P. reticulatus, P. emblica, and P. acidus, through chromatographic separation. The structures of isolated compounds have been elucidated with the help of physical and spectroscopic studies. Medicinal importances of these species have also been discussed.DOI: http://dx.doi.org/10.3329/dujs.v60i1.10327Dhaka Univ. J. Sci. 60(1): 5-10, 2012 (January)

Sterol glucosyltransferase, Ugt51/Atg26, is essential for both micropexophagy and macropexophagy of methanol-induced peroxisomes in Pichia pastoris. However, the role of this protein in pexophagy in other yeast remained unclear. We show that oleate- and amine-induced peroxisomes in Yarrowia lipolytica are degraded by Atg26-independent macropexophagy. Surprisingly, Atg26 was also not essential for macropexophagy of oleate- and amine-induced peroxisomes in P. pastoris, suggesting that the function of sterol glucoside (SG) in pexophagy is both species and peroxisome inducer specific. However, the rates of degradation of oleate- and amine-induced peroxisomes in P. pastoris were reduced in the absence of SG, indicating that P. pastoris specifically uses sterol conversion by Atg26 to enhance selective degradation of peroxisomes. However, methanol-induced peroxisomes apparently have lost the redundant ability to be degraded without SG. We also show that the P. pastoris Vac8 armadillo repeat protein is not essential for macropexophagy of methanol-, oleate-, or amine-induced peroxisomes, which makes PpVac8 the first known protein required for the micropexophagy, but not for the macropexophagy, machinery. The uniqueness of Atg26 and Vac8 functions under different pexophagy conditions demonstrates that not only pexophagy inducers, such as glucose or ethanol, but also the inducers of peroxisomes, such as methanol, oleate, or primary amines, determine the requirements for subsequent pexophagy in yeast.
