TL;DR: Three new diterpenoids, excoecarins V1-V3 (1-3) and a new flavanone glycoside (7) were isolated from the fresh stem of Excoecaria agallocha L.
Abstract: Three new diterpenoids, excoecarins V1-V3 (1-3) and a new flavanone glycoside (7) were isolated from the fresh stem of Excoecaria agallocha L. Their structures were elucidated as: 2alpha,3alpha,18-trihydroxy-3beta,20-epoxybeyer-15-ene (1), ent-2,3-secokaur-16-en-2,3-dioic acid (2), ent-3,4-seco-16alpha-hydroxyatis-4(19)-en-3-oic acid (3), and 3,5,7,3',5'-pentahydroxy-2R,3R-flavanonol 3-O-alpha-L-rhamnopyranoside (7) on the basis of spectroscopic data, chemical evidence, and/or X-ray analysis.

TL;DR: Two new bis-secolabdane diterpenoids, excoecarins R1 and R2, were isolated from the resinous wood of Excoecaria agallocha and established on the basis of spectroscopic data interpretation and chemical evidence.
Abstract: Two new bis-secolabdane diterpenoids, excoecarins R1 (1) and R2 (2), were isolated from the resinous wood of Excoecaria agallocha. The structures of 1 and 2 were established on the basis of spectroscopic data interpretation and chemical evidence.

TL;DR: The ethyl acetate extract of Excoecaria agallocha L. furnished three more new isopimarane diterpenoids, 11 f ,14 f -dihydroxy-7,15-isopimaradien-3-one, ag allochin J, and 6 f,14 f,17-trihydroxy- 7,15 -isopimara-7-15-diene, Agallochin L, (3 ).

TL;DR: Saline and soil character were the main factors that influenced the AMF infection of mangrove.
Abstract: Colonization of the arbuscular mycorrhizal fungi (AMF) on root system of four mangrove plants in Qinzhou Bay was surveyed The AMF spores density in soil of different plant rhizosphere and the intensity of AMF infection were analyzed Excoecaria agallocha possessed the highest spore density,infection intensity,and species richness of AMF,and Aegiceras corniculatum,Kandlia candel,Avicennia marina rank in turns AM structures were not found in the root samples of Avicennia marina Curled and expanded intracellular hyphae,vesicles,and intercellular hyphae were the most discernible AM structures Saline and soil character were the main factors that influenced the AMF infection of mangrove Seventeen AMF were isolated and belong to the genera of Glomus and Acaulospora
