Neo-Clerodane Diterpenoids from Scutellaria altissima [PDF]
Nine neo-clerodane diterpenoids, scutaltisins B-G, scupolin I, scutecolumnin C and 11-epi-scutecolumnin C have been isolated from the acetone extract of the aerial parts of Scutellaria altissima.

Two highly oxygenated nor-clerodane diterpenoids from Croton caudatus
Two highly oxygenated nor-clerodane diterpenoids, crocleropenes A and B (1 and 2), together with four known compounds (3–6) were isolated from the leaves and twigs of Croton caudatus.

Diterpenoid Diversity across Land Plants
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

neo-Clerodane diterpenoids from Scutellaria galericulata [PDF]
By means of preparative HPTLC and column chromatography over silica gel and Sephadex LH-20, fourteen diterpenoids were isolated and purified from the whole plants of Scutellaria galericulata. Based on the physico-chemical properties and spectral data, their structures were elucidated and identified as:scutebarbatine D(1), scutolide A(2), scutolide K(3),

Ecological Drivers of Microbiota Diversity in the Pharmacophagous Turnip Sawfly
We show that both nutritional (host‐plant diet, starvation) and non‐nutritional (pharmacophagy) plant use independently shape microbiota diversity, composition and predicted function in Athalia rosae. Pharmacophagy via clerodanoid uptake altered microbial communities and enriched metabolic pathways linked to plant compound degradation. Wild individuals

Isolation and Identification of -Clerodane Diterpenes from Makino
An extract of the aerial parts of Ajuga nipponensis Makino was examined by HPLC for neo-clerodane diterpenes. The suitability of reversed-phase HPLC for the semi-preparative fractionation of this extract was explored, resulting in the isolation of two ...

Neo-clerodane diterpenes from Ajuga turkestanica [PDF]
The ethyl acetate extract of the aerial parts of Ajuga turkestanica afforded 6 neo-clerodane diterpenes, including two novel compounds, 14, 15-dihydroajugachin B (1) and 14-hydro-15-methoxyajugachin B (2), in addition to the known diterpenoids chamaepitin (3), ajugachin B (4), ajugapitin (5) and lupulin A (6).

A new anti-feedant clerodane diterpenoid from tinospora cordifolia [PDF]
Phytochemical investigation of the chloroform extract of Tinospora cordifolia yielded a new clerodane diterpenoid tincordin (1) along with tinosporide (2), 8-hydroxytinosporide (3), columbin (4), 8-hydroxycolumbin (5) and 10-hydroxycolumbin (6).
