Objective: To study the chemical constituents of the roots of Capparis tenera.
Method: The chemical constituents were isolated and repeatedly purified by kinds of column chromatography and the structures were elucidated by the NMR spectra and physicochemical properties.
Result: Eight compounds were isolated and identified as erigeside C (1), glucosuringic acid (2), vanillic acid 4-O-beta-D-glucoside (3-methoxy 4-glucosyl-benzoic acid) (3), 4-O-beta-D-glucopyranosylbenzoate (4), 3', 5'-dimethoxy- 4-O-beta-D-glucopyranosyl-cinnamic acid (5), tachioside (6), 2, 3-dihydroxy-1-(4-hydroxyl-3, 5-dimethoxyphenyl)-1-propanone (7) and acacetin 7-rutinoside (8).
Conclusion: Compounds 1-8 were all isolated from this plant for the first time and the compound 8 was isolated from this gene for the first time.

Background: A central goal of implementation science is to generate insights that allow evidence-based practices to be successfully applied across diverse settings. However, challenges often arise in preserving programs' effectiveness outside the context of their intervention development. We propose that qualitative data can inform generalizability via elucidating mechanisms of an intervention.

An unusual C nor-halimane-type diterpenoid, norcrohalane A (1), a new nor-lasserane-type sesquiterpenoid, norcrolasane A (2), along with four known compounds (3-6) were isolated from the roots of Croton crassifolius. Compound 1 represents the first example of a C nor-halimane-type diterpenoid, which features a rare 6/6/6 tricyclic ring system, and the A ring is aromatic. Compound 2 is a rare nor-lasserane-type sesquiterpenoid.

Santalum album is an economically important plant in the craft, spices and medicine industries. The main chemical constituents found in sandalwood essential oils are sesquiterpenes. 3-Hydroxy-3-methylglutaryl monoacyl-coenzyme A reductase (HMGR) is one of the rate-limiting enzymes required for the synthesis of sandal sesquiterpenes, but there are no studies on the HMGR gene in S.
