The flowers of Hylocereus undatus (Haw.) Britton & Rose have been reported in vitro antioxidant and tyrosinase inhibitory activities. This study screened preliminarily the triterpenoid constituents and evaluated in vitro tyrosinase inhibitory activity of H. undatus flowers. H. undatus flowers were harvested from Binh Thuan Province, Vietnam at four different flowering stages, and their five separated parts (stamen, pistil, petals, ovary, and sepals) were extracted with ethanol.

Land resources potential assessment is a valuable method for orienting land use planning in the world as well as in Vietnam. This study aimed to (1) assess land suitability and (2) orient the effective use of agricultural land in the study area. Results indicated that Ham Thuan Bac had 107 land mapping units (LMUs) with 11 main landuse types (LUTs) such as rice, cassava, vegetables, dragon fruit, and other trees. Agricultural land with high (S1) and moderate suitability (S2) for most LUTs was small; however, marginal (S3) and not suitability (N) lands were quite large.

Each treatment comprised of one pole having 4 (four) plants. The observations were recorded on days to first flower, flower length, androecium characters, gynoecium characters and different parts of perianth was observed. The days required to first flower was 431.25 days with application of N 350 P2O5250 K2O 200 g/pole and flowering became earlier by nearly 15 days over control. Among the different flower parameters, the length of upper, inner, outer and lower free perianth, style, stamen and the ovary were only significantly influenced due to the different treatments.
